-screen - screen manager with VT100/ANSI terminal emulation
-!!SYNOPSIS
-
-
- __screen__ [[ __-__''options'' ] [[ ''cmd'' [[''args'' ] ]
- __screen -r__ [[[[''pid''.]''tty''[[__.__''host'']]
- __screen -r__ ''sessionowner''/[[[[''pid''.]''tty''[[.''host'']]
-
-!!DESCRIPTION
-
-''Screen'' is a full-screen window manager that
-multiplexes a physical terminal between several processes
-(typically interactive shells). Each virtual terminal
-provides the functions of a DEC VT100 terminal and, in
-addition, several control functions from the ISO 6429 (ECMA
-48, ANSI X3.64) and ISO 2022 standards (e.g. insert/delete
-line and support for multiple character sets). There is a
-scrollback history buffer for each virtual terminal and a
-copy-and-paste mechanism that allows moving text regions
-between windows.
-
-
-When ''screen'' is called, it creates a single window
-with a shell in it (or the specified command) and then gets
-out of your way so that you can use the program as you
-normally would. Then, at any time, you can create new
-(full-screen) windows with other programs in them (including
-more shells), kill existing windows, view a list of windows,
-turn output logging on and off, copy-and-paste text between
-windows, view the scrollback history, switch between windows
-in whatever manner you wish, etc. All windows run their
-programs completely independent of each other. Programs
-continue to run when their window is currently not visible
-and even when the whole ''screen'' session is detached
-from the user's terminal. When a program terminates,
-''screen'' (per default) kills the window that contained
-it. If this window was in the foreground, the display
-switches to the previous window; if none are left,
-''screen'' exits.
-
-
-Everything you type is sent to the program running in the
-current window. The only exception to this is the one
-keystroke that is used to initiate a command to the window
-manager. By default, each command begins with a control-a
-(abbreviated C-a from now on), and is followed by one other
-keystroke. The command character and all the key bindings
-can be fully customized to be anything you like, though they
-are always two characters in length.
-
-
-''Screen'' does not understand the prefix "C-" to mean
-control. Please use the caret notation ("^A" instead of
-"C-a") as arguments to e.g. the "escape" command or
-the "-e" option. ''Screen'' will also print out
-control characters in caret notation.
-
-
-The standard way to create a new window is to type "C-a
-c". This creates a new window running a shell and switches
-to that window immediately, regardless of the state of the
-process running in the current window. Similarly, you can
-create a new window with a custom command in it by first
-binding the command to a keystroke (in your .screenrc file
-or at the "C-a :" command line) and then using it just
-like the "C-a c" command. In addition, new windows can be
-created by running a command like:
-
-;:screen emacs prog.c
-
-
-from a shell prompt within a previously created window. This
-will not run another copy of ''screen'', but will instead
-supply the command name and its arguments to the window
-manager (specified in the $STY environment variable) who
-will use it to create the new window. The above example
-would start the emacs editor (editing prog.c) and switch to
-its window.
-
-
-If "/var/run/utmp" is writable by ''screen'', an
-appropriate record will be written to this file for each
-window, and removed when the window is terminated. This is
-useful for working with "talk", "script", "shutdown",
-"rsend", "sccs" and other similar programs that use the
-utmp file to determine who you are. As long as ''screen''
-is active on your terminal, the terminal's own record is
-removed from the utmp file. See also "C-a L".
-!!GETTING STARTED
-
-
-Before you begin to use ''screen'' you'll need to make
-sure you have correctly selected your terminal type, just as
-you would for any other termcap/terminfo program. (You can
-do this by using ''tset'' for example.)
-
-
-If you're impatient and want to get started without doing a
-lot more reading, you should remember this one command:
-"C-a ?". Typing these two characters will display a list
-of the available ''screen'' commands and their bindings.
-Each keystroke is discussed in the section "DEFAULT KEY
-BINDINGS". The manual section "CUSTOMIZATION" deals with
-the contents of your .screenrc.
-
-
-If your terminal is a "true" auto-margin terminal (it
-doesn't allow the last position on the screen to be updated
-without scrolling the screen) consider to use a version of
-your terminal's termcap that has automatic margins turned
-''off''. This will ensure an accurate and optimal update
-of the screen in all circumstances. Most terminals nowadays
-have "magic" margins (automatic margins plus usable last
-column). This is the VT100 style type and perfectly suited
-for ''screen''. If all you've got is a "true"
-auto-margin terminal ''screen'' will be content to use
-it, but updating a character put into the last position on
-the screen may not be possible until the screen scrolls or
-the character is moved into a safe position in some other
-way. This delay can be shortened by using a terminal with
-insert-character capability.
-
-
-!!COMMAND-LINE OPTIONS
-
-
-Screen has the following command-line options:
-
-
-;__-a__: include ''all'' capabilities (with some minor exceptions) in each window's termcap, even if ''screen'' must redraw parts of the display in order to implement a function.
-
-;__-A__: Adapt the sizes of all windows to the size of the current terminal. By default, ''screen'' tries to restore its old window sizes when attaching to resizable terminals (those with "WS" in its description, e.g. suncmd or some xterm).
-
-;__-c__ ''file'': override the default configuration file from "$HOME/.screenrc" to ''file''.
-
-
-;__-d__|__-D__ [[''pid.tty.host'']: does not start ''screen'', but detaches the elsewhere running ''screen'' session. It has the same effect as typing "C-a d" from ''screen'''s controlling terminal. __-D__ is the equivalent to the power detach key. If no session can be detached, this option is ignored. In combination with the __-r__/__-R__ option more powerful effects can be achieved:
-
-
-;__-d -r__: Reattach a session and if necessary detach it first.
-
-;__-d -R__: Reattach a session and if necessary detach or even create it first.
-
-;__-d -RR__: Reattach a session and if necessary detach or create it. Use the first session if more than one session is available.
-
-;__-D -r__: Reattach a session. If necessary detach and logout remotely first.
-
-:__-D -R__: Attach here and now. In detail this means: If a session is running, then reattach. If necessary detach and logout remotely first. If it was not running create it and notify the user. This is the author's favorite.
-
-;__-D -RR__: Attach here and now. Whatever that means, just do it. Note: It is always a good idea to check the status of your sessions by means of ``screen -list''.
-
-;__-e__ ''xy'': specifies the command character to be ''x'' and the character generating a literal command character to ''y'' (when typed after the command character). The default is ``C-a'' and `a', which can be specified as ``-e^Aa''. When creating a ''screen'' session, this option sets the default command character. In a multiuser session all users added will start off with this command character. But when attaching to an already running session, this option changes only the command character of the attaching user. This option is equivalent to either the commands ``defescape'' or ``escape'' respectively.
-
-;__-f__, __-fn__, and __-fa__: turns flow-control on, off, or "automatic switching mode". This can also be defined through the "defflow" .screenrc command.
-
-;__-h__ ''num'': Specifies the history scrollback buffer to be ''num'' lines high.
-
-;__-i__: will cause the interrupt key (usually C-c) to interrupt the display immediately when flow-control is on. See the "defflow" .screenrc command for details. The use of this option is discouraged.
-
-;__-l__ and __-ln__: turns login mode on or off (for /var/run/utmp updating). This can also be defined through the ``deflogin'' .screenrc command.
-
-;__-ls__ and __-list__: does not start ''screen'', but prints a list of ''pid.tty.host'' strings identifying your ''screen'' sessions. Sessions marked `detached' can be resumed with "screen -r". Those marked `attached' are running and have a controlling terminal. If the session runs in multiuser mode, it is marked `multi'. Sessions marked as `unreachable' either live on a different host or are `dead'. An unreachable session is considered dead, when its name matches either the name of the local host, or the specified parameter, if any. See the __-r__ flag for a description how to construct matches. Sessions marked as `dead' should be thoroughly checked and removed. Ask your system administrator if you are not sure. Remove sessions with the __-wipe__ option.
-
-;__-L__: tells ''screen'' your auto-margin terminal has a writable last-position on the screen. This can also be set in your .screenrc by specifying `LP' in a ``termcap'' command.
-
-;__-m__: causes ''screen'' to ignore the $STY environment variable. With ``screen -m'' creation of a new session is enforced, regardless whether ''screen'' is called from within another ''screen'' session or not. This flag has a special meaning in connection with the `-d' option:
-
-;__-d -m__: Start ''screen'' in "detached" mode. This creates a new session but doesn't attach to it. This is useful for system startup scripts.
-
-;__-D -m__: This also starts screen in ``detached'' mode, but doesn't fork a new process. The command exits if the session terminates.
-
-;__-O__: selects a more optimal output mode for your terminal rather than true VT100 emulation (only affects auto-margin terminals without `LP'). This can also be set in your .screenrc by specifying `OP' in a "termcap" command.
-
-;__-q__: Suppress printing of error messages. In combination with ``-ls'' the exit value is as follows: 9 indicates a directory without sessions. 10 indicates a directory with running but not attachable sessions. 11 (or more) indicates 1 (or more) usable sessions. In combination with ``-r'' the exit value is as follows: 10 indicates that there is no session to resume. 12 (or more) indicates that there are 2 (or more) sessions to resume and you should specify which one to choose. In all other cases "-q" has no effect.
-
-;__-r__ [[''pid.tty.host'']:
-
-;__-r__ ''sessionowner/[[pid.tty.host'']: resumes a detached ''screen'' session. No other options (except combinations with __-d__/__-D__) may be specified, though an optional prefix of [[''pid.'']''tty.host'' may be needed to distinguish between multiple detached ''screen'' sessions. The second form is used to connect to another user's screen session which runs in multiuser mode. This indicates that screen should look for sessions in another user's directory. This requires setuid-root.
-
-;__-R__: attempts to resume the first detached ''screen'' session it finds. If successful, all other command-line options are ignored. If no detached session exists, starts a new session using the specified options, just as if __-R__ had not been specified. The option is set by default if ''screen'' is run as a login-shell (actually screen uses "-xRR" in that case). For combinations with the __-d__/__-D__ option see there.
-
-;__-s__: sets the default shell to the program specified, instead of the value in the environment variable $SHELL (or "/bin/sh" if not defined). This can also be defined through the "shell" .screenrc command.
-
-;__-S__ ''sessionname'': When creating a new session, this option can be used to specify a meaningful name for the session. This name identifies the session for "screen -list" and "screen -r" actions. It substitutes the default [[''tty.host''] suffix.
-
-;__-t__ ''name'': sets the title (a.k.a.) for the default shell or specified program. See also the "shelltitle" .screenrc command.
-
-;__-U__: Run screen in UTF-8 mode. This option tells screen that your terminal sends and understands UTF-8 encoded characters. It also sets the default encoding for new windows to `utf8'.
-
-;__-v__: Print version number.
-
-;__-wipe__ [[''match'']: does the same as "screen -ls", but removes destroyed sessions instead of marking them as `dead'. An unreachable session is considered dead, when its name matches either the name of the local host, or the explicitly given parameter, if any. See the __-r__ flag for a description how to construct matches.
-
-;__-x__: Attach to a not detached ''screen'' session. (Multi display mode).
-
-;__-X__: Send the specified command to a running screen session. You can use the __-d__ or __-r__ option to tell screen to look only for attached or detached screen sessions. Note that this command doesn't work if the session is password protected.
-
-!!DEFAULT KEY BINDINGS
-
-
-As mentioned, each ''screen'' command consists of a
-"C-a" followed by one other character. For your
-convenience, all commands that are bound to lower-case
-letters are also bound to their control character
-counterparts (with the exception of "C-a a"; see below),
-thus, "C-a c" as well as "C-a C-c" can be used to create
-a window. See section "CUSTOMIZATION" for a description of
-the command.

-!!CUSTOMIZATION
-
-
-The ``socket directory'' defaults either to $HOME/.screen or
-simply to /tmp/screens or preferably to /var/run/screen
-chosen at compile-time. If ''screen'' is installed
-setuid-root, then the administrator should compile
-''screen'' with an adequate (not NFS mounted) socket
-directory. If ''screen'' is not running setuid-root, the
-user can specify any mode 700 directory in the environment
-variable $SCREENDIR.
-
-
-When ''screen'' is invoked, it executes initialization
-commands from the files ``/etc/screenrc'' and ``.screenrc''
-in the user's home directory. These are the ``programmer's
-defaults'' that can be overridden in the following ways: for
-the global screenrc file ''screen'' searches for the
-environment variable $SYSSCREENRC (this override feature may
-be disabled at compile-time). The user specific screenrc
-file is searched in $SCREENRC, then $HOME/.screenrc. The
-command line option __-c__ takes precedence over the
-above user screenrc files.
-
-
-Commands in these files are used to set options, bind
-functions to keys, and to automatically establish one or
-more windows at the beginning of your ''screen'' session.
-Commands are listed one per line, with empty lines being
-ignored. A command's arguments are separated by tabs or
-spaces, and may be surrounded by single or double quotes. A
-`#' turns the rest of the line into a comment, except in
-quotes. Unintelligible lines are warned about and ignored.
-Commands may contain references to environment variables.
-The syntax is the shell-like
-''screen'' versions, as now the
-'$'-character has to be protected with '' if no variable
-substitution shall be performed. A string in single-quotes
-is also protected from variable substitution.
-
-
-Two configuration files are shipped as examples with your
-screen distribution: ``etc/screenrc'' and
-``etc/etcscreenrc''. They contain a number of useful
-examples for various commands.
-
-
-Customization can also be done 'on-line'. To enter the
-command mode type `C-a :'. Note that commands starting with
-``def'' change default values, while others change current
-settings.
-
-
-The following commands are available:
-
-
-__acladd__ ''usernames'' [[''crypted-pw'']__
-addacl__ ''usernames''
-
-
-Enable users to fully access this screen session.
-''Usernames'' can be one user or a comma separated list
-of users. This command enables to attach to the
-''screen'' session and performs the equivalent of `aclchg
-''usernames'' +rwx
-''
-
-
-__aclchg__ ''usernames permbits list''__
-chacl__ ''usernames permbits list''
-
-
-Change permissions for a comma separated list of users.
-Permission bits are represented as `r', `w' and `x'.
-Prefixing `+' grants the permission, `-' removes it. The
-third parameter is a comma separated list of commands and/or
-windows (specified either by number or title). The special
-list `#' refers to all windows, `?' to all commands. if
-''usernames'' consists of a single `*', all known users
-are affected. A command can be executed when the user has
-the `x' bit for it. The user can type input to a window when
-he has its `w' bit set and no other user obtains a writelock
-for this window. Other bits are currently ignored. To
-withdraw the writelock from another user in window 2:
-`aclchg ''username'' -w+w 2'. To allow read-only access
-to the session: `aclchg ''username'' -w
-''screen'' he can
-attach to the session and (per default) has full permissions
-for all command and windows. Execution permission for the
-acl commands, `at' and others should also be removed or the
-user may be able to regain write permission. Rights of the
-special username __nobody__ cannot be changed (see the
-``su'' command). `Chacl' is a synonym to `aclchg'. Multi
-user mode only.
-
-
-__acldel__ ''username''
-
-
-Remove a user from ''screen'''s access control list. If
-currently attached, all the user's displays are detached
-from the session. He cannot attach again. Multi user mode
-only.
-
-
-__aclgrp__ ''username''
-[[''groupname'']
-
-
-Creates groups of users that share common access rights. The
-name of the group is the username of the group leader. Each
-member of the group inherits the permissions that are
-granted to the group leader. That means, if a user fails an
-access check, another check is made for the group leader. A
-user is removed from all groups the special value ``none''
-is used for ''groupname''. If the second parameter is
-omitted all groups the user is in are listed.
-
-
-__aclumask__ [[[[''users'']''+bits''
-|[[''users'']''-bits'' .... ]__
-umask__ [[[[''users'']''+bits''
-|[[''users'']''-bits'' .... ]
-
-
-This specifies the access other users have to windows that
-will be created by the caller of the command. ''Users''
-may be no, one or a comma separated list of known usernames.
-If no users are specified, a list of all currently known
-users is assumed. ''Bits'' is any combination of access
-control bits allowed defined with the ``aclchg'' command.
-The special username ``?'' predefines the access that not
-yet known users will be granted to any window initially. The
-special username ``??'' predefines the access that not yet
-known users are granted to any command. Rights of the
-special username __nobody__ cannot be changed (see the
-``su'' command). `Umask' is a synonym to
-`aclumask'.
-
-
-__activity__ ''message''
-
-
-When any activity occurs in a background window that is
-being monitored, ''screen'' displays a notification in
-the message line. The notification message can be re-defined
-by means of the ``activity'' command. Each occurrence of `%'
-in ''message'' is replaced by the number of the window in
-which activity has occurred, and each occurrence of `^G' is
-replaced by the definition for bell in your termcap (usually
-an audible bell). The default message is
-
-
-'Activity in window %n'
-
-
-Note that monitoring is off for all windows by default, but
-can be altered by use of the ``monitor'' command (C-a
-M).
-
-
-__allpartial on__|__off__
-
-
-If set to on, only the current cursor line is refreshed on
-window change. This affects all windows and is useful for
-slow terminal lines. The previous setting of full/partial
-refresh for each window is restored with ``allpartial off''.
-This is a global flag that immediately takes effect on all
-windows overriding the ``partial'' settings. It does not
-change the default redraw behavior of newly created
-windows.
-
-
-__at__ [[''identifier''][[__#__|__*__|__%__]
-''command'' [[''args'' ... ]
-
-
-Execute a command at other displays or windows as if it had
-been entered there. ``At'' changes the context (the `current
-window' or `current display' setting) of the command. If the
-first parameter describes a non-unique context, the command
-will be executed multiple times. If the first parameter is
-of the form `''identifier''*' then identifier is matched
-against user names. The command is executed once for each
-display of the selected user(s). If the first parameter is
-of the form `''identifier''%' identifier is matched
-against displays. Displays are named after the ttys they
-attach. The prefix `/dev/' or `/dev/tty' may be omitted from
-the identifier. If ''identifier'' has a `#' or nothing
-appended it is matched against window numbers and titles.
-Omitting an identifier in front of the `#', `*' or
-`%'-character selects all users, displays or windows because
-a prefix-match is performed. Note that on the affected
-display(s) a short message will describe what happened.
-Permission is checked for initiator of the ``at'' command,
-not for the owners of the affected display(s). Note that the
-'#' character works as a comment introducer when it is
-preceded by whitespace. This can be escaped by prefixing a
-''. Permission is checked for the initiator of the ``at''
-command, not for the owners of the affected display(s).
-Caveat: When matching against windows, the command is
-executed at least once per window. Commands that change the
-internal arrangement of windows (like ``other'') may be
-called again. In shared windows the command will be repeated
-for each attached display. Beware, when issuing toggle
-commands like ``login''! Some commands (e.g. ``stuff'',
-``process'' or ``paste'') require that a display is
-associated with the target windows. These commands may not
-work correctly under ``at'' looping over
-windows.
-
-
-__attrcolor__ ''attrib''
-[[''attribute/color-modifier'']
-
-
-This command can be used to highlight attributes by changing
-the color of the text. If the attribute ''attrib'' is in
-use, the specified attribute/color modifier is also applied.
-If no modifier is given, the current one is deleted. See the
-``STRING ESCAPES'' chapter for the syntax of the modifier.
-Screen understands two pseudo-attributes, ``i'' stands for
-high-intensity foreground color and ``I'' for high-intensity
-background color.
-
-
-Examples:
-
-
-attrcolor b
-
-
-Change the color to bright red if bold text is to be
-printed.
-
-
-attrcolor u
-
-
-Use blue text instead of underline.
-
-
-attrcolor b
-
-
-Use bright colors for bold text. Most terminal emulators do
-this already.
-
-
-attrcolor i
-
-
-Make bright colored text also bold.
-
-
-__autodetach on__|__off__
-
-
-Sets whether ''screen'' will automatically detach upon
-hangup, which saves all your running programs until they are
-resumed with a __screen -r__ command. When turned off, a
-hangup signal will terminate ''screen'' and all the
-processes it contains. Autodetach is on by
-default.
-
-
-__autonuke on__|__off__
-
-
-Sets whether a clear screen sequence should nuke all the
-output that has not been written to the terminal. See also
-``obuflimit''.
-
-
-__bce__ [[__on__|__off__]
-
-
-Change background-color-erase setting. If ``bce'' is set to
-on, all characters cleared by an erase/insert/scroll/clear
-operation will be displayed in the current background color.
-Otherwise the default background color is used.
-
-
-__bell_msg__ [[''message'']
-
-
-When a bell character is sent to a background window,
-''screen'' displays a notification in the message line.
-The notification message can be re-defined by this command.
-Each occurrence of `%' in ''message'' is replaced by the
-number of the window to which a bell has been sent, and each
-occurrence of `^G' is replaced by the definition for bell in
-your termcap (usually an audible bell). The default message
-is
-
-
-'Bell in window %n'
-
-
-An empty message can be supplied to the ``bell_msg'' command
-to suppress output of a message line (bell_msg
-
-
-__bind__ [[__-c__ ''class''] ''key''
-[[''command'' [[''args'']]
-
-
-Bind a command to a key. By default, most of the commands
-provided by ''screen'' are bound to one or more keys as
-indicated in the ``DEFAULT KEY BINDINGS'' section, e.g. the
-command to create a new window is bound to ``C-c'' and
-``c''. The ``bind'' command can be used to redefine the key
-bindings and to define new bindings. The ''key'' argument
-is either a single character, a two-character sequence of
-the form ``^x'' (meaning ``C-x''), a backslash followed by
-an octal number (specifying the ASCII code of the
-character), or a backslash followed by a second character,
-such as ``^'' or ``\''. The argument can also be quoted, if
-you like. If no further argument is given, any previously
-established binding for this key is removed. The
-''command'' argument can be any command listed in this
-section.
-
-
-If a command class is specified via the ``-c'' option, the
-key is bound for the specified class. Use the ``command''
-command to activate a class. Command classes can be used to
-create multiple command keys or multi-character
-bindings.
-
-
-Some examples:
-
-
- bind ' ' windows
-bind ^k
-bind k
-bind K kill
-bind ^f screen telnet foobar
-bind 033 screen -ln -t root -h 1000 9 su
-would bind the space key to the command that displays a list of windows (so that the command usually invoked by ``C-a C-w'' would also be available as ``C-a space''). The next three lines remove the default kill binding from ``C-a C-k'' and ``C-a k''. ``C-a K'' is then bound to the kill command. Then it binds ``C-f'' to the command ``create a window with a TELNET connection to foobar'', and bind ``escape'' to the command that creates an non-login window with a.k.a. ``root'' in slot #9, with a superuser shell and a scrollback buffer of 1000 lines.
-
-
- bind -c demo1 0 select 10
-bind -c demo1 1 select 11
-bind -c demo1 2 select 12
-bindkey
-makes ``C-b '' select window 10, ``C-b 1'' window 11, etc.
-
-
- bind -c demo2 0 select 10
-bind -c demo2 1 select 11
-bind -c demo2 2 select 12
-bind - command -c demo2
-makes ``C-a - '' select window 10, ``C-a - 1'' window 11, etc.
-
-
-__bindkey__ [[__-d__] [[__-m__] [[__-a__]
-[[[[__-k__|__-t__] ''string'' [[''cmd
-args'']]
-
-
-This command manages screen's input translation tables.
-Every entry in one of the tables tells screen how to react
-if a certain sequence of characters is encountered. There
-are three tables: one that should contain actions programmed
-by the user, one for the default actions used for terminal
-emulation and one for screen's copy mode to do cursor
-movement. See section ``INPUT TRANSLATION'' for a list of
-default key bindings.
-If the __-d__ option is given, bindkey modifies the
-default table, __-m__ changes the copy mode table and
-with neither option the user table is selected. The argument
-''string'' is the sequence of characters to which an
-action is bound. This can either be a fixed string or a
-termcap keyboard capability name (selectable with the
-__-k__ option).
-Some keys on a VT100 terminal can send a different string if
-application mode is turned on (e.g the cursor keys). Such
-keys have two entries in the translation table. You can
-select the application mode entry by specifying the
-__-a__ option.
-The __-t__ option tells screen not to do inter-character
-timing. One cannot turn off the timing if a termcap
-capability is used.''
-Cmd'' can be any of screen's commands with an arbitrary
-number of ''args''. If ''cmd'' is omitted the
-key-binding is removed from the table.
-Here are some examples of keyboard bindings:
-
-
- bindkey -d
-Show all of the default key bindings. The application mode entries are marked with [[A].
-
-
- bindkey -k k1 select 1
-Make the
-
-
- bindkey -t foo stuff barfoo
-Make
-
-
- bindkey
-This key-binding makes ``^T'' an escape character for key-bindings. If you did the above ``stuff barfoo'' binding, you can enter the word ``foo'' by typing ``^Tfoo''. If you want to insert a ``^T'' you have to press the key twice (i.e. escape the escape binding).
-
-
- bindkey -k F1 command
-Make the F11 (not F1!) key an alternative screen escape (besides ^A).
-
-
-__break__ [[''duration'']
-
-
-Send a break signal for ''duration''*.25 seconds to this
-window. For non-Posix systems the time interval may be
-rounded up to full seconds. Most useful if a character
-device is attached to the window rather than a shell process
-(See also chapter ``WINDOW TYPES''). The maximum duration of
-a break signal is limited to 15 seconds.
-
-
-__breaktype__ [[''tcsendbreak''|''TIOCSBRK''
-|''TCSBRK'']
-
-
-Choose one of the available methods of generating a break
-signal for terminal devices. This command should affect the
-current window only. But it still behaves identical to
-``defbreaktype''. This will be changed in the future.
-Calling ``breaktype'' with no parameter displays the break
-method for the current window.
-
-
-__bufferfile__ [[''exchange-file'']
-
-
-Change the filename used for reading and writing with the
-paste buffer. If the optional argument to the ``bufferfile''
-command is omitted, the default setting
-(``/tmp/screen-exchange'') is reactivated. The following
-example will paste the system's password file into the
-''screen'' window (using the paste buffer, where a copy
-remains):
-
-
- C-a : bufferfile /etc/passwd
-C-a
-__c1__ [[__on__|__off__]
-
-
-Change c1 code processing. ``C1 on'' tells screen to treat
-the input characters between 128 and 159 as control
-functions. Such an 8-bit code is normally the same as ESC
-followed by the corresponding 7-bit code. The default
-setting is to process c1 codes and can be changed with the
-``defc1'' command. Users with fonts that have usable
-characters in the c1 positions may want to turn this
-off.
-
-
-__caption always__|__splitonly__
-[[''string'']__
-caption string__ [[''string'']
-
-
-This command controls the display of the window captions.
-Normally a caption is only used if more than one window is
-shown on the display (split screen mode). But if the type is
-set to __always__ screen shows a caption even if only one
-window is displayed. The default is
-__splitonly__.
-
-
-The second form changes the text used for the caption. You
-can use all escapes from the ``STRING ESCAPES'' chapter.
-Screen uses a default of `%3n %t'.
-
-
-You can mix both forms by providing a string as an
-additional argument.
-
-
-__charset__ ''set''
-
-
-Change the current character set slot designation and
-charset mapping. The first four character of ''set'' are
-treated as charset designators while the fifth and sixth
-character must be in range '' to '3' and set the GL/GR
-charset mapping. On every position a '.' may be used to
-indicate that the corresponding charset/mapping should not
-be changed (''set'' is padded to six characters
-internally by appending '.' chars). New windows have
-''
-The current setting can be viewed with the ``info''
-command.
-
-
-__chdir__ [[''directory'']
-
-
-Change the ''current directory'' of ''screen'' to the
-specified directory or, if called without an argument, to
-your home directory (the value of the environment variable
-$HOME). All windows that are created by means of the
-``screen'' command from within ``.screenrc'' or by means of
-``C-a : screen ...'' or ``C-a c'' use this as their default
-directory. Without a chdir command, this would be the
-directory from which ''screen'' was invoked. Hardcopy and
-log files are always written to the ''window's'' default
-directory, ''not'' the current directory of the process
-running in the window. You can use this command multiple
-times in your .screenrc to start various windows in
-different default directories, but the last chdir value will
-affect all the windows you create
-interactively.
-
-
-__clear__
-
-
-Clears the current window and saves its image to the
-scrollback buffer.
-
-
-__colon__ [[''prefix'']
-
-
-Allows you to enter ``.screenrc'' command lines. Useful for
-on-the-fly modification of key bindings, specific window
-creation and changing settings. Note that the ``set''
-keyword no longer exists! Usually commands affect the
-current window rather than default settings for future
-windows. Change defaults with commands starting with
-'def...'.
-
-
-If you consider this as the `Ex command mode' of
-''screen'', you may regard ``C-a esc'' (copy mode) as its
-`Vi command mode'.
-
-
-__command__ [[__-c__ ''class'']
-
-
-This command has the same effect as typing the screen escape
-character (^A). It is probably only useful for key bindings.
-If the ``-c'' option is given, select the specified command
-class. See also ``bind'' and ``bindkey''.
-
-
-__compacthist__ [[__on__|__off__]
-
-
-This tells screen weather to suppress trailing blank lines
-when scrolling up text into the history buffer.
-
-
-__console__ [[__on__|__off__]
-
-
-Grabs or un-grabs the machines console output to a window.
-''Note'': Only the owner of /dev/console can grab the
-console output. This command is only available if the
-machine supports the ioctl TIOCCONS.
-
-
-__copy__
-
-
-Enter copy/scrollback mode. This allows you to copy text
-from the current window and its history into the paste
-buffer. In this mode a vi-like `full screen editor' is
-active:''
-Movement keys'':
-
-
-__h__, __j__, __k__, __l__ move the cursor line
-by line or column by column.
-
-
-____, __^__ and __$__ move to the leftmost column,
-to the first or last non-whitespace character on the
-line.
-
-
-__H__, __M__ and __L__ move the cursor to the
-leftmost column of the top, center or bottom line of the
-window.
-
-
-__+__ and __-__ positions one line up and
-down.
-
-
-__G__ moves to the specified absolute line (default: end
-of buffer).
-
-
-__|__ moves to the specified absolute
-column.
-
-
-__w__, __b__, __e__ move the cursor word by
-word.
-
-
-__C-u__ and __C-d__ scroll the display up/down by the
-specified amount of lines while preserving the cursor
-position. (Default: half screen-full).
-
-
-__C-b__ and __C-f__ scroll the display up/down a full
-screen.
-
-
-__g__ moves to the beginning of the buffer.
-
-
-__%__ jumps to the specified percentage of the
-buffer.
-
-
-''Note'':
-
-
-Emacs style movement keys can be customized by a .screenrc
-command. (E.g. markkeys
-
-
-''Marking'':
-
-
-The copy range is specified by setting two marks. The text
-between these marks will be highlighted. Press
-
-
-__space__ to set the first or second mark
-respectively.
-
-
-__Y__ and __y__ used to mark one whole line or to mark
-from start of line.
-
-
-__W__ marks exactly one word.
-
-
-''Repeat count'':
-
-
-Any of these commands can be prefixed with a repeat count
-number by pressing digits
-
-
-____..__9__ which is taken as a repeat
-count.
-
-
-Example: ``C-a C-[[ H 10 j 5 Y'' will copy lines 11 to 15
-into the paste buffer.
-
-
-''Searching'':
-
-
-__/__ ''Vi''-like search forward. __?__
-''Vi''-like search backward. __C-a s__ ''Emacs''
-style incremental search forward. __C-r__ ''Emacs''
-style reverse i-search.
-
-
-''Specials'':
-
-
-There are however some keys that act differently than in
-''vi''. ''Vi'' does not allow one to yank rectangular
-blocks of text, but ''screen'' does. Press__
-c__ or __C__ to set the left or right margin
-respectively. If no repeat count is given, both default to
-the current cursor position.
-Example: Try this on a rather full text screen: ``C-a [[ M 20
-l SPACE c 10 l 5 j C SPACE''.
-
-
-This moves one to the middle line of the screen, moves in 20
-columns left, marks the beginning of the paste buffer, sets
-the left column, moves 5 columns down, sets the right
-column, and then marks the end of the paste buffer. Now
-try:
-``C-a [[ M 20 l SPACE 10 l 5 j SPACE''
-
-
-and notice the difference in the amount of text
-copied.__
-J__ joins lines. It toggles between 4 modes: lines
-separated by a newline character (012), lines glued
-seamless, lines separated by a single whitespace and comma
-separated lines. Note that you can prepend the newline
-character with a carriage return character, by issuing a
-``crlf on''.__
-v__ is for all the ''vi'' users with ``:set numbers'' -
-it toggles the left margin between column 9 and 1.
-Press__
-a__ before the final space key to toggle in append mode.
-Thus the contents of the paste buffer will not be
-overwritten, but is appended to.__
-A__ toggles in append mode and sets a (second)
-mark.__
- sets the (second) mark and writes the contents of
-the paste buffer to the screen-exchange file
-(/tmp/screen-exchange per default) once copy-mode is
-finished.
-This example demonstrates how to dump the whole scrollback
-buffer to that file: ``C-A [[ g SPACE G $
-C-g__ gives information about the current line and
-column.__
-x__ exchanges the first mark and the current cursor
-position. You can use this to adjust an already placed
-mark.__
-@__ does nothing. Does not even exit copy mode.
-All keys not described here exit copy mode.
-
-
-__copy_reg__ [[''key'']
-
-
-No longer exists, use ``readreg'' instead.
-
-
-__crlf__ [[__on__|__off__]
-
-
-This affects the copying of text regions with the `C-a [['
-command. If it is set to `on', lines will be separated by
-the two character sequence `CR' - `LF'. Otherwise (default)
-only `LF' is used. When no parameter is given, the state is
-toggled.
-
-
-__debug on__|__off__
-
-
-Turns runtime debugging on or off. If ''screen'' has been
-compiled with option -DDEBUG debugging available and is
-turned on per default. Note that this command only affects
-debugging output from the main ``SCREEN'' process correctly.
-Debug output from attacher processes can only be turned off
-once and forever.
-
-
-__defc1 on__|__off__
-
-
-Same as the __c1__ command except that the default
-setting for new windows is changed. Initial setting is
-`on'.
-
-
-__defautonuke on__|__off__
-
-
-Same as the __autonuke__ command except that the default
-setting for new displays is changed. Initial setting is
-`off'. Note that you can use the special `AN' terminal
-capability if you want to have a dependency on the terminal
-type.
-
-
-__defbce on__|__off__
-
-
-Same as the __bce__ command except that the default
-setting for new windows is changed. Initial setting is
-`off'.
-
-
-__defbreaktype__ [[''tcsendbreak''|''TIOCSBRK''
-|''TCSBRK'']
-
-
-Choose one of the available methods of generating a break
-signal for terminal devices. The preferred methods are
-''tcsendbreak'' and ''TIOCSBRK''. The third,
-''TCSBRK'', blocks the complete ''screen'' session for
-the duration of the break, but it may be the only way to
-generate long breaks. ''Tcsendbreak'' and ''TIOCSBRK''
-may or may not produce long breaks with spikes (e.g. 4 per
-second). This is not only system dependant, this also
-differs between serial board drivers. Calling
-``defbreaktype'' with no parameter displays the current
-setting.
-
-
-__defcharset__ [[''set'']
-
-
-Like the __charset__ command except that the default
-setting for new windows is changed. Shows current default if
-called without argument.
-
-
-__defescape__ ''xy''
-
-
-Set the default command characters. This is equivalent to
-the ``escape'' except that it is useful multiuser sessions
-only. In a multiuser session ``escape'' changes the command
-character of the calling user, where ``defescape'' changes
-the default command characters for users that will be added
-later.
-
-
-__defflow on__|__off__|__auto__
-[[__interrupt__]
-
-
-Same as the __flow__ command except that the default
-setting for new windows is changed. Initial setting is
-`auto'. Specifying ``defflow auto interrupt'' is the same as
-the command-line options __-fa__ and
-__-i__.
-
-
-__defgr on__|__off__
-
-
-Same as the __gr__ command except that the default
-setting for new windows is changed. Initial setting is
-`off'.
-
-
-__defhstatus__ [[''status'']
-
-
-The hardstatus line that all new windows will get is set to
-''status''. This command is useful to make the hardstatus
-of every window display the window number or title or the
-like. ''Status'' may contain the same directives as in
-the window messages, but the directive escape character is
-'^E' (octal 005) instead of '%'. This was done to make a
-misinterpretation of program generated hardstatus lines
-impossible. If the parameter ''status'' is omitted, the
-current default string is displayed. Per default the
-hardstatus line of new windows is empty.
-
-
-__defencoding__ ''enc''
-
-
-Same as the __encoding__ command except that the default
-setting for new windows is changed. Initial setting is the
-encoding taken from the terminal.
-
-
-__deflog on__|__off__
-
-
-Same as the __log__ command except that the default
-setting for new windows is changed. Initial setting is
-`off'.
-
-
-__deflogin on__|__off__
-
-
-Same as the __login__ command except that the default
-setting for new windows is changed. This is initialized with
-`on' as distributed (see config.h.in).
-
-
-__defmode__ ''mode''
-
-
-The mode of each newly allocated pseudo-tty is set to
-''mode''. ''Mode'' is an octal number. When no
-``defmode'' command is given, mode 0622 is
-used.
-
-
-__defmonitor on__|__off__
-
-
-Same as the __monitor__ command except that the default
-setting for new windows is changed. Initial setting is
-`off'.
-
-
-__defobuflimit__ ''limit''
-
-
-Same as the __obuflimit__ command except that the default
-setting for new displays is changed. Initial setting is 256
-bytes. Note that you can use the special 'OL' terminal
-capability if you want to have a dependency on the terminal
-type.
-
-
-__defscrollback__ ''num''
-
-
-Same as the __scrollback__ command except that the
-default setting for new windows is changed. Initial setting
-is 100.
-
-
-__defshell__ ''command''
-
-
-Synonym to the __shell__ command. See there.
-
-
-__defsilence on__|__off__
-
-
-Same as the __silence__ command except that the default
-setting for new windows is changed. Initial setting is
-`off'.
-
-
-__defslowpaste__ ''msec''
-
-
-Same as the __slowpaste__ command except that the default
-setting for new windows is changed. Initial setting is
-milliseconds, meaning `off'.
-
-
-__defutf8 on__|__off__
-
-
-Same as the __utf8__ command except that the default
-setting for new windows is changed. Initial setting is `on'
-if screen was started with ``-U'', otherwise
-`off'.
-
-
-__defwrap on__|__off__
-
-
-Same as the __wrap__ command except that the default
-setting for new windows is changed. Initially line-wrap is
-on and can be toggled with the ``wrap'' command (``C-a r'')
-or by means of __
-
-
-__defwritelock on__|__off__|__auto__
-
-
-Same as the __writelock__ command except that the default
-setting for new windows is changed. Initially writelocks
-will off.
-
-
-__defzombie__ [[''keys'']
-
-
-Synonym to the __zombie__ command. Both currently change
-the default. See there.
-
-
-__detach__ [[__-h__]
-
-
-Detach the ''screen'' session (disconnect it from the
-terminal and put it into the background). This returns you
-to the shell where you invoked ''screen''. A detached
-''screen'' can be resumed by invoking ''screen'' with
-the __-r__ option (see also section ``COMMAND-LINE
-OPTIONS''). The __-h__ option tells screen to immediately
-close the connection to the terminal
-(``hangup'').
-
-
-__dinfo__
-
-
-Show what screen thinks about your terminal. Useful if you
-want to know why features like color or the alternate
-charset don't work.
-
-
-__displays__
-
-
-Shows a tabular listing of all currently connected user
-front-ends (displays). This is most useful for multiuser
-sessions.
-
-
-__digraph__ [[''preset'']
-
-
-This command prompts the user for a digraph sequence. The
-next two characters typed are looked up in a builtin table
-and the resulting character is inserted in the input stream.
-For example, if the user enters 'a
-screen'' will treat the following characters (up to
-three) as an octal number instead. The optional argument
-''preset'' is treated as user input, thus one can create
-an ``umlaut'' key. For example the command
-''

-
-Write the termcap entry for the virtual terminal optimized
-for the currently active window to the file ``.termcap'' in
-the user's ``$HOME/.screen'' directory (or wherever
-''screen'' stores its sockets. See the ``FILES'' section
-below). This termcap entry is identical to the value of the
-environment variable $TERMCAP that is set up by
-''screen'' for each window. For terminfo based systems
-you will need to run a converter like ''captoinfo'' and
-then compile the entry with ''tic''.
-
-
-__echo__ [[__-n__] ''message''
-
-
-The echo command may be used to annoy ''screen'' users
-with a 'message of the day'. Typically installed in a global
-/etc/screenrc. The option ``-n'' may be used to suppress the
-line feed. See also ``sleep''. Echo is also useful for
-online checking of environment variables.
-
-
-__escape__ ''xy''
-
-
-Set the command character to ''x'' and the character
-generating a literal command character (by triggering the
-``meta'' command) to ''y'' (similar to the -e option).
-Each argument is either a single character, a two-character
-sequence of the form ``^x'' (meaning ``C-x''), a backslash
-followed by an octal number (specifying the ASCII code of
-the character), or a backslash followed by a second
-character, such as ``^'' or ``\''. The default is
-``^Aa''.
-
-
-__eval__ ''command1'' [[''command2
-...'']
-
-
-Parses and executes each argument as seperate
-command.
-
-
-__exec__ [[[[''fdpat''] ''newcommand'' [[''args
-...'']]
-
-
-Run a unix subprocess (specified by an executable path
-''newcommand'' and its optional arguments) in the current
-window. The flow of data between newcommands
-stdin/stdout/stderr, the process originally started in the
-window (let us call it
-''screen''. An exclamation mark (!) causes the file
-descriptor to be connected to the application-process. A
-colon (:) combines both. User input will go to newcommand
-unless newcommand receives the application-process' output
-(fdpats first character is `!' or `:') or a pipe symbol (|)
-is added (as a fourth character) to the end of fdpat.
-Invoking `exec' without arguments shows name and arguments
-of the currently running subprocess in this window. Only one
-subprocess a time can be running in each window.
-When a subprocess is running the `kill' command will affect
-it instead of the windows process.
-Refer to the postscript file `doc/fdpat.ps' for a confusing
-illustration of all 21 possible combinations. Each drawing
-shows the digits 2,1,0 representing the three file
-descriptors of newcommand. The box marked `W' is the usual
-pty that has the application-process on its slave side. The
-box marked `P' is the secondary pty that now has
-''screen'' at its master side.
-
-
-Abbreviations:
-Whitespace between the word `exec' and fdpat and the command
-can be omitted. Trailing dots and a fdpat consisting only of
-dots can be omitted. A simple `|' is synonymous for the
-pattern `!..|'; the word exec can be omitted here and can
-always be replaced by `!'.
-
-
-Examples:
-
-
-exec ... /bin/sh
-exec /bin/sh
-!/bin/sh
-
-
-Creates another shell in the same window, while the original
-shell is still running. Output of both shells is displayed
-and user input is sent to the new /bin/sh.
-
-
-exec !.. stty 19200
-exec ! stty 19200
-!!stty 19200
-
-
-Set the speed of the window's tty. If your stty command
-operates on stdout, then add another `!'.
-
-
-exec !..| less
-|less
-
-
-This adds a pager to the window output. The special
-character `|' is needed to give the user control over the
-pager although it gets its input from the window's process.
-This works, because ''less'' listens on stderr (a
-behavior that ''screen'' would not expect without the
-`|') when its stdin is not a tty. ''Less'' versions newer
-than 177 fail miserably here; good old ''pg'' still
-works.
-
-
-!:sed -n s/.*Error.*/007/p
-
-
-Sends window output to both, the user and the sed command.
-The sed inserts an additional bell character (oct. 007) to
-the window output seen by ''screen''. This will cause
-''
-
-
-__fit__
-
-
-Change the window size to the size of the current region.
-This command is needed because screen doesn't adapt the
-window size automatically if the window is displayed more
-than once.
-
-
-__flow__ [[__on__|__off__|__auto__]
-
-
-Sets the flow-control mode for this window. Without
-parameters it cycles the current window's flow-control
-setting from
-
-
-__focus__
-[[__up__|__down__|__top__|__bottom__]
-
-
-Move the input focus to the next region. This is done in a
-cyclic way so that the top region is selected after the
-bottom one. If no subcommand is given it defaults to `down'.
-`up' cycles in the opposite order, `top' and `bottom' go to
-the top and bottom region respectively. Useful bindings are
-(j and k as in vi)
-
-
- bind j focus down
-bind k focus up
-bind t focus top
-bind b focus bottom
-__gr__ [[__on__|__off__]
-
-
-Turn GR charset switching on/off. Whenever screen sees an
-input character with the 8th bit set, it will use the
-charset stored in the GR slot and print the character with
-the 8th bit stripped. The default (see also ``defgr'') is
-not to process GR switching because otherwise the ISO88591
-charset would not work.
-
-
-__hardcopy__ [[__-h__] [[''file'']
-
-
-Writes out the currently displayed image to the file
-''file'', or, if no filename is specified, to
-''hardcopy.n'' in the default directory, where ''n''
-is the number of the current window. This either appends or
-overwrites the file if it exists. See below. If the option
-__-h__ is specified, dump also the contents of the
-scrollback buffer.
-
-
-__hardcopy_append on__|__off__
-
-
-If set to screen'' will append to the
-''
-
-
-__hardcopydir__ ''directory''
-
-
-Defines a directory where hardcopy files will be placed. If
-unset, hardcopys are dumped in ''screen'''s current
-working directory.
-
-
-__hardstatus__ [[__on__|__off__]__
-hardstatus__
-[[__always__]__lastline__|__message__|__ignore__
-[[''string'']__
-hardstatus string__ [[''string'']
-
-
-This command configures the use and emulation of the
-terminal's hardstatus line. The first form toggles whether
-''screen'' will use the hardware status line to display
-messages. If the flag is set to `off', these messages are
-overlaid in reverse video mode at the display line. The
-default setting is `on'.
-
-
-The second form tells ''screen'' what to do if the
-terminal doesn't have a hardstatus line (i.e. the
-termcap/terminfo capabilities
-''screen'' will
-reserve the last line of the display for the hardstatus.
-``message'' uses ''screen's'' message mechanism and
-``ignore'' tells ''screen'' never to display the
-hardstatus. If you prepend the word ``always'' to the type,
-''screen'' will use the type even if the terminal
-supports a hardstatus.
-
-
-The third form specifies the contents of the hardstatus
-line. '%h' is used as default string, i.e. the stored
-hardstatus of the current window (settable via
-``ESC];
-string'', the current
-string is displayed.
-
-
-You can mix the second and third form by providing the
-string as additional argument.
-
-
-__height__ [[__-w__|__-d__] [[''lines''
-[[''cols'']]
-
-
-Set the display height to a specified number of lines. When
-no argument is given it toggles between 24 and 42 lines
-display. You can also specify a width if you want to change
-both values. The __-w__ option tells screen to leave the
-display size unchanged and just set the window size,
-__-d__ vice versa.
-
-
-__help__ [[__-c__ ''class'']
-
-
-Not really a online help, but displays a help ''screen''
-showing you all the key bindings. The first pages list all
-the internal commands followed by their current bindings.
-Subsequent pages will display the custom commands, one
-command per key. Press space when you're done reading each
-page, or return to exit early. All other characters are
-ignored. If the ``-c'' option is given, display all bound
-commands for the specified command class. See also ``DEFAULT
-KEY BINDINGS'' section.
-
-
-__history__
-
-
-Usually users work with a shell that allows easy access to
-previous commands. For example csh has the command ``!!'' to
-repeat the last command executed. ''Screen'' allows you
-to have a primitive way of re-calling ``the command that
-started ...'': You just type the first letter of that
-command, then hit `C-a {' and ''screen'' tries to find a
-previous line that matches with the `prompt character' to
-the left of the cursor. This line is pasted into this
-window's input queue. Thus you have a crude command history
-(made up by the visible window and its scrollback
-buffer).
-
-
-__hstatus__ ''status''
-
-
-Change the window's hardstatus line to the string
-''status''.
-
-
-__ignorecase__ [[__on__|__off__]
-
-
-Tell screen to ignore the case of caracters in searches.
-Default is `off'.
-
-
-__info__
-
-
-Uses the message line to display some information about the
-current window: the cursor position in the form
-``(column,row)'' starting with ``(1,1)'', the terminal width
-and height plus the size of the scrollback buffer in lines,
-like in ``(80,24)+50'', the current state of window XON/XOFF
-flow control is shown like this (See also section FLOW
-CONTROL):
-
-
- +flow automatic flow control, currently on.
--flow automatic flow control, currently off.
-+(+)flow flow control enabled. Agrees with automatic control.
--(+)flow flow control disabled. Disagrees with automatic control.
-+(-)flow flow control enabled. Disagrees with automatic control.
--(-)flow flow control disabled. Agrees with automatic control.
-The current line wrap setting (`+wrap' indicates enabled, `-wrap' not) is also shown. The flags `ins', `org', `app', `log', `mon' or `nored' are displayed when the window is in insert mode, origin mode, application-keypad mode, has output logging, insert mode, origin mode, application-keypad mode, output logging, activity monitoring or partial redraw enabled.
-
-
-The currently active character set (''G0'', ''G1'',
-''G2'', or ''G3'') and in square brackets the terminal
-character sets that are currently designated as ''G0''
-through ''G3'' is shown. If the window is in UTF-8 mode,
-the string ``UTF-8'' is shown instead.
-
-
-Additional modes depending on the type of the window are
-displayed at the end of the status line (See also chapter
-``WINDOW TYPES'').
-If the state machine of the terminal emulator is in a
-non-default state, the info line is started with a string
-identifying the current state.
-For system information use the ``time''
-command.
-
-
-__ins_reg__ [[''key'']
-
-
-No longer exists, use ``paste'' instead.
-
-
-__encoding__ ''enc'' [[''enc'']
-
-
-Tell ''screen'' how to interpret the input/output. The
-first argument sets the encoding of the current window. Each
-window can emulate a different encoding. The optional second
-parameter overwrites the encoding of the connected terminal.
-It should never be needed as screen uses the locale setting
-to detect the encoding. There is also a way to select a
-terminal encoding depending on the terminal type by using
-the ``KJ'' termcap entry.
-
-
-Supported encodings are eucJP, SJIS, eucKR, eucCN, Big5,
-KOI8-R, CP1251, UTF-8, ISO8859-2, ISO8859-3, ISO8859-4,
-ISO8859-5, ISO8859-6, ISO8859-7, ISO8859-8, ISO8859-9,
-ISO8859-10, ISO8859-15, jis.
-
-
-See also ``defencoding'', which changes the default setting
-of a new window.
-
-
-__kill__
-
-
-Kill current window.
-If there is an `exec' command running then it is killed.
-Otherwise the process (shell) running in the window receives
-a HANGUP condition, the window structure is removed and
-''screen'' (your display) switches to another window.
-When the last window is destroyed, ''screen'' exits.
-After a kill ''screen'' switches to the previously
-displayed window.
-Note: ''Emacs'' users should keep this command in mind,
-when killing a line. It is recommended not to use ``C-a'' as
-the ''screen'' escape key or to rebind kill to ``C-a
-K''.
-
-
-__lastmsg__
-
-
-Redisplay the last contents of the message/status line.
-Useful if you're typing when a message appears, because the
-message goes away when you press a key (unless your terminal
-has a hardware status line). Refer to the commands
-``msgwait'' and ``msgminwait'' for fine tuning.
-
-
-__license__
-
-
-Display the disclaimer page. This is done whenever
-''screen'' is started without options, which should be
-often enough. See also the ``startup_message''
-command.
-
-
-__lockscreen__
-
-
-Lock this display. Call a screenlock program (/local/bin/lck
-or /usr/bin/lock or a builtin if no other is available).
-Screen does not accept any command keys until this program
-terminates. Meanwhile processes in the windows may continue,
-as the windows are in the `detached' state. The screenlock
-program may be changed through the environment variable
-$LOCKPRG (which must be set in the shell from which
-''screen'' is started) and is executed with the user's
-uid and gid.
-Warning: When you leave other shells unlocked and you have
-no password set on ''screen'', the lock is void: One
-could easily re-attach from an unlocked shell. This feature
-should rather be called `lockterminal'.
-
-
-__log__ [[__on__|__off__]
-
-
-Start/stop writing output of the current window to a file
-``screenlog.''n'''' in the window's default directory,
-where ''n'' is the number of the current window. This
-filename can be changed with the `logfile' command. If no
-parameter is given, the state of logging is toggled. The
-session log is appended to the previous contents of the file
-if it already exists. The current contents and the contents
-of the scrollback history are not included in the session
-log. Default is `off'.
-
-
-__logfile__ ''filename''__
-logfile flush__ ''secs''
-
-
-Defines the name the logfiles will get. The default is
-``screenlog.%n''. The second form changes the number of
-seconds ''screen'' will wait before flushing the logfile
-buffer to the file-system. The default value is 10
-seconds.
-
-
-__login__ [[__on__|__off__]
-
-
-Adds or removes the entry in the utmp database file for the
-current window. This controls if the window is `logged in'.
-When no parameter is given, the login state of the window is
-toggled. Additionally to that toggle, it is convenient
-having a `log in' and a `log out' key. E.g. `bind I login
-on' and `bind O login off' will map these keys to be C-a I
-and C-a O. The default setting (in config.h.in) should be
-``on'' for a ''screen'' that runs under suid-root. Use
-the ``deflogin'' command to change the default login state
-for new windows. Both commands are only present when
-''screen'' has been compiled with utmp
-support.
-
-
-__logtstamp__ [[__on__|__off__]__
-logtstamp after__ [[''secs'']__
-logtstamp string__ [[''string'']
-
-
-This command controls logfile time-stamp mechanism of
-''screen.'' If time-stamps are turned ``on'',
-''screen'' adds a string containing the current time to
-the logfile after two minutes of inactivity. When output
-continues and more than another two minutes have passed, a
-second time-stamp is added to document the restart of the
-output. You can change this timeout with the second form of
-the command. The third form is used for customizing the
-time-stamp string (`-- %n:%t -- time-stamp -- %M/%d/%y %c:%s
---n' by default).
-
-
-__mapdefault__
-
-
-Tell ''screen'' that the next input character should only
-be looked up in the default bindkey table. See also
-``bindkey''.
-
-
-__mapnotnext__
-
-
-Like mapdefault, but don't even look in the default bindkey
-table.
-
-
-__maptimeout__ [[''timo'']
-
-
-Set the inter-character timer for input sequence detection
-to a timeout of ''timo'' ms. The default timeout is
-300ms. Maptimeout with no arguments shows the current
-setting. See also ``bindkey''.
-
-
-__markkeys__ ''string''
-
-
-This is a method of changing the keymap used for
-copy/history mode. The string is made up of
-''oldchar''=''newchar'' pairs which are separated by
-`:'. Example: The string ``B=^B:F=^F'' will change the keys
-`C-b' and `C-f' to the vi style binding (scroll up/down fill
-page). This happens to be the default binding for `B' and
-`F'. The command ``markkeys h=^B:l=^F:$=^E'' would set the
-mode for an emacs-style binding. If your terminal sends
-characters, that cause you to abort copy mode, then this
-command may help by binding these characters to do nothing.
-The no-op character is `@' and is used like this: ``markkeys
-@=L=H'' if you do not want to use the `H' or `L' commands
-any longer. As shown in this example, multiple keys can be
-assigned to one function in a single statement.
-
-
-__meta__
-
-
-Insert the command character (C-a) in the current window's
-input stream.
-
-
-__monitor__ [[__on__|__off__]
-
-
-Toggles activity monitoring of windows. When monitoring is
-turned on and an affected window is switched into the
-background, you will receive the activity notification
-message in the status line at the first sign of output and
-the window will also be marked with an `@' in the
-window-status display. Monitoring is initially off for all
-windows.
-
-
-__msgminwait__ ''sec''
-
-
-Defines the time ''screen'' delays a new message when one
-message is currently displayed. The default is 1
-second.
-
-
-__msgwait__ ''sec''
-
-
-Defines the time a message is displayed if ''screen'' is
-not disturbed by other activity. The default is 5
-seconds.
-
-
-__multiuser on__|__off__
-
-
-Switch between singleuser and multiuser mode. Standard
-''screen'' operation is singleuser. In multiuser mode the
-commands `acladd', `aclchg', `aclgrp' and `acldel' can be
-used to enable (and disable) other users accessing this
-''screen'' session.
-
-
-__nethack on__|__off__
-
-
-Changes the kind of error messages used by ''screen''.
-When you are familiar with the game ``nethack'', you may
-enjoy the nethack-style messages which will often blur the
-facts a little, but are much funnier to read. Anyway,
-standard messages often tend to be unclear as well.
-This option is only available if ''screen'' was compiled
-with the NETHACK flag defined. The default setting is then
-determined by the presence of the environment variable
-$NETHACKOPTIONS.
-
-
-__next__
-
-
-Switch to the next window. This command can be used
-repeatedly to cycle through the list of
-windows.
-
-
-__nonblock__ [[__on__|__off__]
-
-
-Enable or disable flow control for the current user
-interface (display). It is used to prevent a slow display
-from slowing down the processing of data output by a window.
-This command may be helpful when multiple displays show the
-same window. Nonblock is initially off for all
-displays.
-
-
-__number__ [[''n'']
-
-
-Change the current windows number. If the given number
-''n'' is already used by another window, both windows
-exchange their numbers. If no argument is specified, the
-current window number (and title) is shown.
-
-
-__obuflimit__ [[''limit'']
-
-
-If the output buffer contains more bytes than the specified
-limit, no more data will be read from the windows. The
-default value is 256. If you have a fast display (like
-xterm), you can set it to some higher value. If no argument
-is specified, the current setting is displayed.
-
-
-__only__
-
-
-Kill all regions but the current one.
-
-
-__other__
-
-
-Switch to the window displayed previously. If this window
-does no longer exist, ''other'' has the same effect as
-''next''.
-
-
-__partial on__|__off__
-
-
-Defines whether the display should be refreshed (as with
-''redisplay'') after switching to the current window.
-This command only affects the current window. To immediately
-affect all windows use the ''allpartial'' command.
-Default is `off', of course. This default is fixed, as there
-is currently no ''defpartial'' command.
-
-
-__password__ [[''crypted_pw'']
-
-
-Present a crypted password in your ``.screenrc'' file and
-''screen'' will ask for it, whenever someone attempts to
-resume a detached. This is useful if you have privileged
-programs running under ''screen'' and you want to protect
-your session from reattach attempts by another user
-masquerading as your uid (i.e. any superuser.) If no crypted
-password is specified, ''screen'' prompts twice for
-typing a password and places its encryption in the paste
-buffer. Default is `none', this disables password
-checking.
-
-
-__paste__ [[''registers''
-[[''dest_reg'']]
-
-
-Write the (concatenated) contents of the specified registers
-to the stdin queue of the current window. The register '.'
-is treated as the paste buffer. If no parameter is given the
-user is prompted for a single register to paste. The paste
-buffer can be filled with the ''copy'', ''history''
-and ''readbuf'' commands. Other registers can be filled
-with the ''register'', ''readreg'' and ''paste''
-commands. If ''paste'' is called with a second argument,
-the contents of the specified registers is pasted into the
-named destination register rather than the window. If '.' is
-used as the second argument, the displays paste buffer is
-the destination. Note, that ``paste'' uses a wide variety of
-resources: Whenever a second argument is specified no
-current window is needed. When the source specification only
-contains registers (not the paste buffer) then there need
-not be a current display (terminal attached), as the
-registers are a global resource. The paste buffer exists
-once for every user.
-
-
-__pastefont__ [[__on__|__off__]
-
-
-Tell ''screen'' to include font information in the paste
-buffer. The default is not to do so. This command is
-especially useful for multi character fonts like
-kanji.
-
-
-__pow_break__
-
-
-Reopen the window's terminal line and send a break
-condition. See `break'.
-
-
-__pow_detach__
-
-
-Power detach. Mainly the same as ''detach'', but also
-sends a HANGUP signal to the parent process of
-''screen''. CAUTION: This will result in a logout, when
-''screen'' was started from your login
-shell.
-
-
-__pow_detach_msg__ [[''message'']
-
-
-The ''message'' specified here is output whenever a
-`Power detach' was performed. It may be used as a
-replacement for a logout message or to reset baud rate, etc.
-Without parameter, the current message is
-shown.
-
-
-__prev__
-
-
-Switch to the window with the next lower number. This
-command can be used repeatedly to cycle through the list of
-windows.
-
-
-__printcmd__ [[''cmd'']
-
-
-If ''cmd'' is not an empty string, ''screen'' will not
-use the terminal capabilities ``po/pf'' if it detects an
-ansi print sequence __ESC [[ 5 i__, but pipe the output
-into ''cmd''. This should normally be a command like
-``lpr'' or ``'cat ''printcmd__
-without a command displays the current setting. The ansi
-sequence __ESC \__ ends printing and closes the pipe.
-Warning: Be careful with this command! If other user have
-write access to your terminal, they will be able to fire off
-print commands.
-
-
-__process__ [[''key'']
-
-
-Stuff the contents of the specified register into
-''screen'''s input queue. If no argument is given you are
-prompted for a register name. The text is parsed as if it
-had been typed in from the user's keyboard. This command can
-be used to bind multiple actions to a single
-key.
-
-
-__quit__
-
-
-Kill all windows and terminate ''screen''. Note that on
-VT100-style terminals the keys C-4 and C-\ are identical.
-This makes the default bindings dangerous: Be careful not to
-type C-a C-4 when selecting window no. 4. Use the empty bind
-command (as in ``bind '^''') to remove a key
-binding.
-
-
-__readbuf__ [[__-e__ ''encoding'']
-[[''filename'']
-
-
-Reads the contents of the specified file into the paste
-buffer. You can tell screen the encoding of the file via the
-__-e__ option. If no file is specified, the
-screen-exchange filename is used. See also ``bufferfile''
-command.
-
-
-__readreg__ [[__-e__ ''encoding''] [[''register''
-[[''filename'']]
-
-
-Does one of two things, dependent on number of arguments:
-with zero or one arguments it it duplicates the paste buffer
-contents into the register specified or entered at the
-prompt. With two arguments it reads the contents of the
-named file into the register, just as ''readbuf'' reads
-the screen-exchange file into the paste buffer. You can tell
-screen the encoding of the file via the __-e__ option.
-The following example will paste the system's password file
-into the ''screen'' window (using register p, where a
-copy remains):
-
-
- C-a : readreg p /etc/passwd
-C-a : paste p
-__redisplay__
-
-
-Redisplay the current window. Needed to get a full redisplay
-when in partial redraw mode.
-
-
-__register__ [[__-e__ ''encoding''] ''key
-string''
-
-
-Save the specified ''string'' to the register ''key''.
-The encoding of the string can be specified via the
-__-e__ option. See also the ``paste''
-command.
-
-
-__remove__
-
-
-Kill the current region. This is a no-op if there is only
-one region.
-
-
-__removebuf__
-
-
-Unlinks the screen-exchange file used by the commands
-``writebuf'' and ``readbuf''.
-
-
-__reset__
-
-
-Reset the virtual terminal to its ``power-on'' values.
-Useful when strange settings (like scroll regions or
-graphics character set) are left over from an
-application.
-
-
-__resize__
-
-
-Resize the current region. The space will be removed from or
-added to the region below or if there's not enough space
-from the region above.
-
-
-resize +N increase current region height by N
-
-
-resize -N decrease current region height by N
-
-
-resize N set current region height to N
-
-
-resize = make all windows equally high
-
-
-resize max maximize current region height
-
-
-resize min minimize current region height
-
-
-__screen__ [[''-opts''] [[''n''] [[''cmd''
-[[''args'']]
-
-
-Establish a new window. The flow-control options (__-f__,
-__-fn__ and __-fa__), title (a.k.a.) option
-(__-t__), login options (__-l__ and __-ln__) ,
-terminal type option (__-T__
-__-a__) and scrollback option
-(__-h__
-__-M__) turns monitoring on for this window.
-The option (__-L__) turns output logging on for this
-window. If an optional number ''n'' in the range ..9 is
-given, the window number ''n'' is assigned to the newly
-created window (or, if this number is already in-use, the
-next available number). If a command is specified after
-``screen'', this command (with the given arguments) is
-started in the window; otherwise, a shell is created. Thus,
-if your ``.screenrc'' contains the lines
-
-
- # example for .screenrc:
-screen 1
-screen -fn -t foobar -L 2 telnet foobar
-''screen'' creates a shell window (in window #1) and a window with a TELNET connection to the machine foobar (with no flow-control using the title ``foobar'' in window #2) and will write a logfile (``screenlog.2'') of the telnet session. Note, that unlike previous versions of ''screen'' no additional default window is created when ``screen'' commands are included in your ``.screenrc'' file. When the initialization is completed, ''screen'' switches to the last window specified in your .screenrc file or, if none, opens a default window #.
-Screen has built in some functionality of ``cu'' and ``telnet''. See also chapter ``WINDOW TYPES''.
-
-
-__scrollback__ ''num''
-
-
-Set the size of the scrollback buffer for the current
-windows to ''num'' lines. The default scrollback is 100
-lines. See also the ``defscrollback'' command and use ``C-a
-i'' to view the current setting.
-
-
-__select__ [[''WindowID'']
-
-
-Switch to the window identified by ''WindowID''. This can
-be a prefix of a window title (alphanumeric window name) or
-a window number. The parameter is optional and if omitted,
-you get prompted for an identifier. When a new window is
-established, the first available number is assigned to this
-window. Thus, the first window can be activated by ``select
-''. The number of windows is limited at compile-time by the
-MAXWIN configuration parameter.
-
-
-__sessionname__ [[''name'']
-
-
-Rename the current session. Note, that for ``screen -list''
-the name shows up with the process-id prepended. If the
-argument ``name'' is omitted, the name of this session is
-displayed. Caution: The $STY environment variables still
-reflects the old name. This may result in confusion. The
-default is constructed from the tty and host
-names.
-
-
-__setenv__ [[''var'' [[''string'']]
-
-
-Set the environment variable ''var'' to value
-''string''. If only ''var'' is specified, the user
-will be prompted to enter a value. If no parameters are
-specified, the user will be prompted for both variable and
-value. The environment is inherited by all subsequently
-forked shells.
-
-
-__setsid__ [[__on__|__off__]
-
-
-Normally screen uses different sessions and process groups
-for the windows. If setsid is turned ''off'', this is not
-done anymore and all windows will be in the same process
-group as the screen backend process. This also breaks
-job-control, so be careful. The default is ''on'', of
-course. This command is probably useful only in rare
-circumstances.
-
-
-__shell__ ''command''
-
-
-Set the command to be used to create a new shell. This
-overrides the value of the environment variable $SHELL. This
-is useful if you'd like to run a tty-enhancer which is
-expecting to execute the program specified in $SHELL. If the
-command begins with a '-' character, the shell will be
-started as a login-shell.
-
-
-__shelltitle__ ''title''
-
-
-Set the title for all shells created during startup or by
-the C-A C-c command. For details about what a title is, see
-the discussion entitled ``TITLES (naming
-windows)''.
-
-
-__silence__
-[[__on__|__off__|''sec'']
-
-
-Toggles silence monitoring of windows. When silence is
-turned on and an affected window is switched into the
-background, you will receive the silence notification
-message in the status line after a specified period of
-inactivity (silence). The default timeout can be changed
-with the `silencewait' command or by specifying a number of
-seconds instead of `on' or `off'. Silence is initially off
-for all windows.
-
-
-__silencewait__ ''sec''
-
-
-Define the time that all windows monitored for silence
-should wait before displaying a message. Default 30
-seconds.
-
-
-__sleep__ ''num''
-
-
-This command will pause the execution of a .screenrc file
-for ''num'' seconds. Keyboard activity will end the
-sleep. It may be used to give users a chance to read the
-messages output by ``echo''.
-
-
-__slowpaste__ ''msec''
-
-
-Define the speed at which text is inserted into the current
-window by the paste (
-screen'' will make a pause of ''msec''
-milliseconds after each single character write to allow the
-application to process its input. Only use slowpaste if your
-underlying system exposes flow control problems while
-pasting large amounts of text.
-
-
-__source__ ''file''
-
-
-Read and execute commands from file ''file''. Source
-commands may be nested to a maximum recursion level of ten.
-If file is not an absolute path and screen already processes
-a source command, the parent directory of the running source
-command file is used to search for the new command file
-before screen's current directory.
-
-
-Note that termcap/terminfo/termcapinfo commands only work at
-startup and reattach time, so they must be reached via the
-default screenrc files to have an effect.
-
-
-__sorendition__ [[''attr'' [[''color'']]
-
-
-Change the way ''screen'' does highlighting for text
-marking and printing messages. See the ``STRING ESCAPES''
-chapter for the syntax of the modifiers. The default is
-currently ``=s dd'' (standout, default colors).
-
-
-__split__
-
-
-Split the current region into two new ones. All regions on
-the display are resized to make room for the new region. The
-blank window is displayed on the new region.
-
-
-__startup_message on__|__off__
-
-
-Select whether you want to see the copyright notice during
-startup. Default is `on', as you probably
-noticed.
-
-
-__stuff__ ''string''
-
-
-Stuff the string ''string'' in the input buffer of the
-current window. This is like the ``paste'' command but with
-much less overhead. You cannot paste large buffers with the
-``stuff'' command. It is most useful for key bindings. See
-also ``bindkey''.
-
-
-__su__ [[__username__ [[__password__
-[[__password2__]]
-
-
-Substitute the user of a display. The command prompts for
-all parameters that are omitted. If passwords are specified
-as parameters, they have to be specified un-crypted. The
-first password is matched against the systems passwd
-database, the second password is matched against the
-''screen'' password as set with the commands ``acladd''
-or ``password''. ``Su'' may be useful for the ''screen''
-administrator to test multiuser setups. When the
-identification fails, the user has access to the commands
-available for user __nobody__. These are ``detach'',
-``license'', ``version'', ``help'' and
-``displays''.
-
-
-__suspend__
-
-
-Suspend ''screen''. The windows are in the `detached'
-state, while ''screen'' is suspended. This feature relies
-on the shell being able to do job control.
-
-
-__term__ ''term''
-
-
-In each window's environment ''screen'' opens, the $TERM
-variable is set to ``screen'' by default. But when no
-description for ``screen'' is installed in the local termcap
-or terminfo data base, you set $TERM to - say - ``vt100''.
-This won't do much harm, as ''screen'' is VT100/ANSI
-compatible. The use of the ``term'' command is discouraged
-for non-default purpose. That is, one may want to specify
-special $TERM settings (e.g. vt100) for the next ``screen
-rlogin othermachine'' command. Use the command ``screen -T
-vt100 rlogin othermachine'' rather than setting and
-resetting the default.
-
-
-__termcap__ ''term terminal-tweaks''
-[[''window-tweaks'']__
-terminfo__ ''term terminal-tweaks''
-[[''window-tweaks'']__
-termcapinfo__ ''term terminal-tweaks''
-[[''window-tweaks'']
-
-
-Use this command to modify your terminal's termcap entry
-without going through all the hassles involved in creating a
-custom termcap entry. Plus, you can optionally customize the
-termcap generated for the windows. You have to place these
-commands in one of the screenrc startup files, as they are
-meaningless once the terminal emulator is booted.
-If your system works uses the terminfo database rather than
-termcap, ''screen'' will understand the `terminfo'
-command, which has the same effects as the `termcap'
-command. Two separate commands are provided, as there are
-subtle syntactic differences, e.g. when parameter
-interpolation (using `%') is required. Note that termcap
-names of the capabilities have to be used with the
-`terminfo' command.
-In many cases, where the arguments are valid in both
-terminfo and termcap syntax, you can use the command
-`termcapinfo', which is just a shorthand for a pair of
-`termcap' and `terminfo' commands with identical
-arguments.
-
-
-The first argument specifies which terminal(s) should be
-affected by this definition. You can specify multiple
-terminal names by separating them with `|'s. Use `*' to
-match all terminals and `vt*' to match all terminals that
-begin with ``vt''.
-
-
-Each ''tweak'' argument contains one or more termcap
-defines (separated by `:'s) to be inserted at the start of
-the appropriate termcap entry, enhancing it or overriding
-existing values. The first tweak modifies your terminal's
-termcap, and contains definitions that your terminal uses to
-perform certain functions. Specify a null string to leave
-this unchanged (e.g. ''). The second (optional) tweak
-modifies all the window termcaps, and should contain
-definitions that ''screen'' understands (see the
-``VIRTUAL TERMINAL'' section).
-
-
-Some examples:
-
-
-termcap xterm* LP:hs@
-
-
-Informs ''screen'' that all terminals that begin with
-`xterm' have firm auto-margins that allow the last position
-on the screen to be updated (LP), but they don't really have
-a status line (no 'hs' - append `@' to turn entries off).
-Note that we assume `LP' for all terminal names that start
-with ``vt'', but only if you don't specify a termcap command
-for that terminal.
-
-
-termcap vt* LP
-termcap vt102|vt220 Z0=E[[?3h:Z1=E[[?3l
-
-
-Specifies the firm-margined `LP' capability for all
-terminals that begin with `vt', and the second line will
-also add the escape-sequences to switch into (Z0) and back
-out of (Z1) 132-character-per-line mode if this is a VT102
-or VT220. (You must specify Z0 and Z1 in your termcap to use
-the width-changing commands.)
-
-
-termcap vt100
-
-
-This leaves your vt100 termcap alone and adds the function
-key labels to each window's termcap entry.
-
-
-termcap h19|z19 am@:im=E@:ei=EO dc=E[[P
-
-
-Takes a h19 or z19 termcap and turns off auto-margins (am@)
-and enables the insert mode (im) and end-insert (ei)
-capabilities (the `@' in the `im' string is after the `=',
-so it is part of the string). Having the `im' and `ei'
-definitions put into your terminal's termcap will cause
-''screen'' to automatically advertise the
-character-insert capability in each window's termcap. Each
-window will also get the delete-character capability (dc)
-added to its termcap, which ''screen'' will translate
-into a line-update for the terminal (we're pretending it
-doesn't support character deletion).
-
-
-If you would like to fully specify each window's termcap
-entry, you should instead set the $SCREENCAP variable prior
-to running ''screen''. See the discussion on the
-``VIRTUAL TERMINAL'' in this manual, and the termcap(5) man
-page for more information on termcap
-definitions.
-
-
-__time__ [[''string'']
-
-
-Uses the message line to display the time of day, the host
-name, and the load averages over 1, 5, and 15 minutes (if
-this is available on your system). For window specific
-information use ``info''.
-
-
-If a string is specified, it changes the format of the time
-report like it is described in the ``STRING ESCAPES''
-chapter. Screen uses a default of
-
-
-__title__ [[''windowalias'']
-
-
-Set the name of the current window to ''windowalias''. If
-no name is specified, ''screen'' prompts for one. This
-command was known as `aka' in previous
-releases.
-
-
-__unsetenv__ ''var''
-
-
-Unset an environment variable.
-
-
-__utf8__ [[__on__|__off__
-[[__on__|__off__]]
-
-
-Change the encoding used in the current window. If utf8 is
-enabled, the strings sent to the window will be UTF-8
-encoded and vice versa. Omitting the parameter toggles the
-setting. If a second parameter is given, the display's
-encoding is also changed (this should rather be done with
-screen's ``-U'' option). See also ``defutf8'', which changes
-the default setting of a new window.
-
-
-__vbell__ [[__on__|__off__]
-
-
-Sets the visual bell setting for this window. Omitting the
-parameter toggles the setting. If vbell is switched on, but
-your terminal does not support a visual bell, a
-`vbell-message' is displayed in the status line when the
-bell character (^G) is received. Visual bell support of a
-terminal is defined by the termcap variable `vb' (terminfo:
-'flash').
-Per default, vbell is off, thus the audible bell is used.
-See also `bell_msg'.
-
-
-__vbell_msg__ [[''message'']
-
-
-Sets the visual bell message. ''message'' is printed to
-the status line if the window receives a bell character
-(^G), vbell is set to ``on'', but the terminal does not
-support a visual bell. The default message is ``Wuff,
-Wuff!!''. Without parameter, the current message is
-shown.
-
-
-__vbellwait__ ''sec''
-
-
-Define a delay in seconds after each display of
-''screen'''s visual bell message. The default is 1
-second.
-
-
-__verbose__ [[__on__|__off__]
-
-
-If verbose is switched on, the command name is echoed,
-whenever a window is created (or resurrected from zombie
-state). Default is off. Without parameter, the current
-setting is shown.
-
-
-__version__
-
-
-Print the current version and the compile date in the status
-line.
-
-
-__wall__ ''message''
-
-
-Write a message to all displays. The message will appear in
-the terminal's status line.
-
-
-__width__ [[__-w__|__-d__] [[''cols''
-[[''lines'']]
-
-
-Toggle the window width between 80 and 132 columns or set it
-to ''cols'' columns if an argument is specified. This
-requires a capable terminal and the termcap entries ``Z0''
-and ``Z1''. See the ``termcap'' command for more
-information. You can also specify a new height if you want
-to change both values. The __-w__ option tells screen to
-leave the display size unchanged and just set the window
-size, __-d__ vice versa.
-
-
-__windowlist__ [[__-b__] | __string__
-[[''string''] | __title__ [[''title'']
-
-
-Display all windows in a table for visual window selection.
-The desired window can be selected via the standard movement
-keys (see the ``copy'' command) and activated via the return
-key. If the __-b__ option is given, screen will switch to
-the blank window before presenting the list, so that the
-current window is also selectable.
-
-
-The table format can be changed with the __string__ and
-__title__ option, the title is displayed as table
-heading, while the lines are made by using the string
-setting. The default setting is ``Num Name%=Flags'' for the
-title and ``%3n %t%=%f'' for the lines. See the ``STRING
-ESCAPES'' chapter for more codes (e.g. color
-settings).
-
-
-__windows__
-
-
-Uses the message line to display a list of all the windows.
-Each window is listed by number with the name of process
-that has been started in the window (or its title); the
-current window is marked with a `*'; the previous window is
-marked with a `-'; all the windows that are ``logged in''
-are marked with a `$'; a background window that has received
-a bell is marked with a `!'; a background window that is
-being monitored and has had activity occur is marked with an
-`@'; a window which has output logging turned on is marked
-with `(L)'; windows occupied by other users are marked with
-`
-
-
-__wrap__ [[__on__|__off__]
-
-
-Sets the line-wrap setting for the current window. When
-line-wrap is on, the second consecutive printable character
-output at the last column of a line will wrap to the start
-of the following line. As an added feature, backspace (^H)
-will also wrap through the left margin to the previous line.
-Default is `on'.
-
-
-__writebuf__ [[__-e__ ''encoding'']
-[[''filename'']
-
-
-Writes the contents of the paste buffer to the specified
-file, or the public accessible screen-exchange file if no
-filename is given. This is thought of as a primitive means
-of communication between ''screen'' users on the same
-host. If an encoding is specified the paste buffer is
-recoded on the fly to match the encoding. The filename can
-be set with the ''bufferfile'' command and defaults to
-``/tmp/screen-exchange''.
-
-
-__writelock__
-[[__on__|__off__|__auto__]
-
-
-In addition to access control lists, not all users may be
-able to write to the same window at once. Per default,
-writelock is in `auto' mode and grants exclusive input
-permission to the user who is the first to switch to the
-particular window. When he leaves the window, other users
-may obtain the writelock (automatically). The writelock of
-the current window is disabled by the command ``writelock
-off''. If the user issues the command ``writelock on'' he
-keeps the exclusive write permission while switching to
-other windows.
-
-
-__xoff
-xon__
-
-
-Insert a CTRL-s / CTRL-q character to the stdin queue of the
-current window.
-
-
-__zombie__ [[''keys'']__
-defzombie__ [[''keys'']
-
-
-Per default ''screen'' windows are removed from the
-window list as soon as the windows process (e.g. shell)
-exits. When a string of two keys is specified to the zombie
-command, `dead' windows will remain in the list. The
-__kill__ command may be used to remove such a window.
-Pressing the first key in the dead window has the same
-effect. When pressing the second key, ''screen'' will
-attempt to resurrect the window. The process that was
-initially running in the window will be launched again.
-Calling __zombie__ without parameters will clear the
-zombie setting, thus making windows disappear when their
-process exits.
-
-
-As the zombie-setting is manipulated globally for all
-windows, this command should only be called
-__defzombie__. Until we need this as a per window
-setting, the commands __zombie__ and __defzombie__ are
-synonymous.
-!!THE MESSAGE LINE
-
-
-''Screen'' displays informational messages and other
-diagnostics in a ''message line''. While this line is
-distributed to appear at the bottom of the screen, it can be
-defined to appear at the top of the screen during
-compilation. If your terminal has a status line defined in
-its termcap, ''screen'' will use this for displaying its
-messages, otherwise a line of the current screen will be
-temporarily overwritten and output will be momentarily
-interrupted. The message line is automatically removed after
-a few seconds delay, but it can also be removed early (on
-terminals without a status line) by beginning to
-type.
-
-
-The message line facility can be used by an application
-running in the current window by means of the ANSI
-''Privacy message'' control sequence. For instance, from
-within the shell, try something like:
-
-
-echo '
-
-
-where 'escape'', '^' is a literal
-up-arrow, and '\' turns into a single
-backslash.
-!!WINDOW TYPES
-
-
-Screen provides three different window types. New windows
-are created with ''screen'''s __screen__ command (see
-also the entry in chapter ``CUSTOMIZATION''). The first
-parameter to the __screen__ command defines which type of
-window is created. The different window types are all
-special cases of the normal type. They have been added in
-order to allow ''screen'' to be used efficiently as a
-console multiplexer with 100 or more windows.
-
-
-The normal window contains a shell (default, if no parameter
-is given) or any other system command that could be executed
-from a shell (e.g. __slogin__, etc...)
-
-
-If a tty (character special device) name (e.g.
-``/dev/ttya'') is specified as the first parameter, then the
-window is directly connected to this device. This window
-type is similar to ``screen cu -l /dev/ttya''. Read and
-write access is required on the device node, an exclusive
-open is attempted on the node to mark the connection line as
-busy. An optional parameter is allowed consisting of a comma
-separated list of flags in the notation used by
-stty(1):
-
-
-
-
-Usually 300, 1200, 9600 or 19200. This affects transmission
-as well as receive speed.
-
-
-cs8 or cs7
-
-
-Specify the transmission of eight (or seven) bits per
-byte.
-
-
-ixon or -ixon
-
-
-Enables (or disables) software flow-control (CTRL-S/CTRL-Q)
-for sending data.
-
-
-ixoff or -ixon
-
-
-Enables (or disables) software flow-control for receiving
-data.
-
-
-istrip or -istrip
-
-
-Clear (or keep) the eight bit in each received
-byte.
-
-
-You may want to specify as many of these options as
-applicable. Unspecified options cause the terminal driver to
-make up the parameter values of the connection. These values
-are system dependant and may be in defaults or values saved
-from a previous connection.
-
-
-For tty windows, the __info__ command shows some of the
-modem control lines in the status line. These may include
-`RTS', `CTS', 'DTR', `DSR', `CD' and more. This depends on
-the available ioctl()'s and system header files as well as
-the on the physical capabilities of the serial board.
-Signals that are logical low (inactive) have their name
-preceded by an exclamation mark (!), otherwise the signal is
-logical high (active). Signals not supported by the hardware
-but available to the ioctl() interface are usually shown
-low.
-When the CLOCAL status bit is true, the whole set of modem
-signals is placed inside curly braces ({ and }). When the
-CRTSCTS or TIOCSOFTCAR bit is set, the signals `CTS' or `CD'
-are shown in parenthesis, respectively.
-
-
-For tty windows, the command __break__ causes the Data
-transmission line (TxD) to go low for a specified period of
-time. This is expected to be interpreted as break signal on
-the other side. No data is sent and no modem control line is
-changed when a __break__ is issued.
-
-
-If the first parameter is ``//telnet'', the second parameter
-is expected to be a host name, and an optional third
-parameter may specify a TCP port number (default decimal
-23). Screen will connect to a server listening on the remote
-host and use the telnet protocol to communicate with that
-server.
-For telnet windows, the command __info__ shows details
-about the connection in square brackets ([[ and ]) at the end
-of the status line.
-
-
-b
-
-
-BINARY. The connection is in binary mode.
-
-
-e
-
-
-ECHO. Local echo is disabled.
-
-
-c
-
-
-SGA. The connection is in `character mode' (default: `line
-mode').
-
-
-t
-
-
-TTYPE. The terminal type has been requested by the remote
-host. Screen sends the name ``screen'' unless instructed
-otherwise (see also the command `term').
-
-
-w
-
-
-NAWS. The remote site is notified about window size
-changes.
-
-
-f
-
-
-LFLOW. The remote host will send flow control information.
-(Ignored at the moment.)
-
-
-Additional flags for debugging are x, t and n (XDISPLOC,
-TSPEED and NEWENV).
-
-
-For telnet windows, the command __break__ sends the
-telnet code IAC BREAK (decimal 243) to the remote
-host.
-
-
-This window type is only available if ''screen'' was
-compiled with the BUILTIN_TELNET option
-defined.
-!!STRING ESCAPES
-
-
-Screen provides an escape mechanism to insert information
-like the current time into messages or file names. The
-escape character is '%' with one exception: inside of a
-window's hardstatus '^%' ('^E') is used
-instead.
-
-
-Here is the full list of supported escapes:
-
-
-%
-
-
-the escape character itself
-
-
-a
-
-
-either 'am' or 'pm'
-

-day number
-
-
-D
-
-
-weekday name
-

-
-
-flags of the window

-F
-
-
-sets %? to true if the window has the focus
-
-

-pad the string to the display's width (like TeX's hfill). If
-a number is specified, pad to the percentage of the window's
-width. A '' qualifier tells screen to treat the number as
-absolute position. You can specify to pad relative to the
-last absolute pad position by adding a '+' qualifier or to
-pad relative to the right margin by using '-'. The padding
-truncates the string if the specified position lies before
-the current position. Add the 'L' qualifier to change

-specified by the truncation operator.) The 'L' qualifier
-tells screen to mark the truncated parts with

-
-The 'c' and 'C' escape may be qualified with a '' to make
-''screen'' use zero instead of space as fill character.
-The '' qualifier also makes the '=' escape use absolute
-positions. The 'n' and '=' escapes understand a length
-qualifier (e.g. '%3n'), 'D' and 'M' can be prefixed with 'L'
-to generate long names, 'w' and 'W' also show the window
-flags if 'L' is given.
-
-
-An attribute/color modifier is is used to change the
-attributes or the color settings. Its format is ``[[attribute
-modifier] [[color description]''. The attribute modifier must
-be prefixed by a change type indicator if it can be confused
-with a color desciption. The following change types are
-known:
-
-
-+
-
-
-add the specified set to the current attributes
-
-
--
-
-
-remove the set from the current attributes
-
-
-!
-
-
-invert the set in the current attributes
-
-
-=
-
-
-change the current attributes to the specified
-set
-
-
-The attribute set can either be specified as a hexadecimal
-number or a combination of the following

-
-

-Colors are coded either as a hexadecimal number or two
-letters specifying the desired background and foreground
-color (in that order). The following colors are
-known:

-
-
-leave color unchanged
-
-
-The capitalized versions of the letter specify bright
-colors. You can also use the pseudo-color 'i' to set just
-the brightness and leave the color unchanged.
-A one digit/letter color description is treated as
-foreground or background color dependant on the current
-attributes: if reverse mode is set, the background color is
-changed instead of the foreground color. If you don't like
-this, prefix the color with a ``.''. If you want the same
-behaviour for two-letter color descriptions, also prefix
-them with a ``.''.
-As a special case, ``%{-}'' restores the attributes and
-colors that were set before the last change was made (i.e.
-pops one level of the color-change stack).
-
-
-Examples:
-
-
-``G''
-
-
-set color to bright green
-
-
-``+b r''
-
-
-use bold red
-
-
-``= yd''
-
-
-clear all attributes, write in default color on yellow
-background.
-
-
-%-Lw%{= BW}%50
-
-
-The available windows centered at the current window and
-truncated to the available width. The current window is
-displayed white on blue. This can be used with ``hardstatus
-alwayslastline''.
-
-
-%?%F%{.R.}%?%3n %t%? [[%h]%?
-
-
-The window number and title and the window's hardstatus, if
-one is set. Also use a red background if this is the active
-focus. Useful for ``caption string''.
-!!FLOW-CONTROL
-
-
-Each window has a flow-control setting that determines how
-''screen'' deals with the XON and XOFF characters (and
-perhaps the interrupt character). When flow-control is
-turned off, ''screen'' ignores the XON and XOFF
-characters, which allows the user to send them to the
-current program by simply typing them (useful for the
-''emacs'' editor, for instance). The trade-off is that it
-will take longer for output from a ``normal'' program to
-pause in response to an XOFF. With flow-control turned on,
-XON and XOFF characters are used to immediately pause the
-output of the current window. You can still send these
-characters to the current program, but you must use the
-appropriate two-character ''screen'' commands (typically
-``C-a q'' (xon) and ``C-a s'' (xoff)). The xon/xoff commands
-are also useful for typing C-s and C-q past a terminal that
-intercepts these characters.
-
-
-Each window has an initial flow-control value set with
-either the __-f__ option or the ``defflow'' .screenrc
-command. Per default the windows are set to automatic
-flow-switching. It can then be toggled between the three
-states 'fixed on', 'fixed off' and 'automatic' interactively
-with the ``flow'' command bound to
-__
-
-
-The automatic flow-switching mode deals with flow control
-using the TIOCPKT mode (like ``rlogin'' does). If the tty
-driver does not support TIOCPKT, ''screen'' tries to find
-out the right mode based on the current setting of the
-application keypad - when it is enabled, flow-control is
-turned off and visa versa. Of course, you can still
-manipulate flow-control manually when needed.
-
-
-If you're running with flow-control enabled and find that
-pressing the interrupt key (usually C-c) does not interrupt
-the display until another 6-8 lines have scrolled by, try
-running ''screen'' with the ``interrupt'' option (add the
-``interrupt'' flag to the ``flow'' command in your
-.screenrc, or use the __-i__ command-line option). This
-causes the output that ''screen'' has accumulated from
-the interrupted program to be flushed. One disadvantage is
-that the virtual terminal's memory contains the non-flushed
-version of the output, which in rare cases can cause minor
-inaccuracies in the output. For example, if you switch
-screens and return, or update the screen with ``C-a l'' you
-would see the version of the output you would have gotten
-without ``interrupt'' being on. Also, you might need to turn
-off flow-control (or use auto-flow mode to turn it off
-automatically) when running a program that expects you to
-type the interrupt character as input, as it is possible to
-interrupt the output of the virtual terminal to your
-physical terminal when flow-control is enabled. If this
-happens, a simple refresh of the screen with ``C-a l'' will
-restore it. Give each mode a try, and use whichever mode you
-find more comfortable.
-!!TITLES (naming windows)
-
-
-You can customize each window's name in the window display
-(viewed with the ``windows'' command (C-a w)) by setting it
-with one of the title commands. Normally the name displayed
-is the actual command name of the program created in the
-window. However, it is sometimes useful to distinguish
-various programs of the same name or to change the name
-on-the-fly to reflect the current state of the
-window.
-
-
-The default name for all shell windows can be set with the
-``shelltitle'' command in the .screenrc file, while all
-other windows are created with a ``screen'' command and thus
-can have their name set with the __-t__ option.
-Interactively, there is the title-string escape-sequence
-(__name''
-''
-
-
-Finally, ''screen'' has a shell-specific heuristic that
-is enabled by setting the window's name to
-``''search|name'''' and arranging to have a null title
-escape-sequence output as a part of your prompt. The
-''search'' portion specifies an end-of-prompt search
-string, while the ''name'' portion specifies the default
-shell name for the window. If the ''name'' ends in a `:'
-''screen'' will add what it believes to be the current
-command running in the window to the end of the window's
-shell name (e.g. ``''name:cmd''''). Otherwise the current
-command name supersedes the shell name while it is
-running.
-
-
-Here's how it works: you must modify your shell prompt to
-output a null title-escape-sequence
-(
-search'' portion of the title. Once
-this is set up, ''screen'' will use the
-title-escape-sequence to clear the previous command name and
-get ready for the next command. Then, when a newline is
-received from the shell, a search is made for the end of the
-prompt. If found, it will grab the first word after the
-matched string and use it as the command name. If the
-command name begins with either '!', '%', or '^'
-''screen'' will use the first word on the following line
-(if found) in preference to the just-found name. This helps
-csh users get better command names when using job control or
-history recall commands.
-
-
-Here's some .screenrc examples:
-
-
-screen -t top 2 nice top
-
-
-Adding this line to your .screenrc would start a nice-d
-version of the ``top'' command in window 2 named ``top''
-rather than ``nice''.
-
-
- shelltitle '
-These commands would start a shell with the given shelltitle. The title specified is an auto-title that would expect the prompt and the typed command to look something like the following:
-
-
-/usr/joe/src/dir
-
-
-(it looks after the '
-
-
-bind R screen -t '% |root:' su
-
-
-Having this command in your .screenrc would bind the key
-sequence ``C-a R'' to the ``su'' command and give it an
-auto-title name of ``root:''. For this auto-title to work,
-the screen could look something like this:
-
-
- % !em
-emacs file.c
-Here the user typed the csh history command ``!em'' which ran the previously entered ``emacs'' command. The window status would show ``root:emacs'' during the execution of the command, and revert to simply ``root:'' at its completion.
-
-
- bind o title
-bind E title
-The first binding doesn't have any arguments, so it would prompt you for a title. when you type ``C-a o''. The second binding would clear an auto-title's current setting (C-a E). The third binding would set the current window's title to ``(unknown)'' (C-a u).
-
-
-One thing to keep in mind when adding a null
-title-escape-sequence to your prompt is that some shells
-(like the csh) count all the non-control characters as part
-of the prompt's length. If these invisible characters aren't
-a multiple of 8 then backspacing over a tab will result in
-an incorrect display. One way to get around this is to use a
-prompt like this:
-
-
-set prompt='^[[[[0000m^[[k^[[% '
-
-
-The escape-sequence ``
-
-
-PROMPT_COMMAND='echo -n -e
-
-
-(I used ``134'' to output a `' because of a bug in bash
-v1.04).
-!!THE VIRTUAL TERMINAL
-
-
-Each window in a ''screen'' session emulates a VT100
-terminal, with some extra functions added. The VT100
-emulator is hard-coded, no other terminal types can be
-emulated.
-Usually ''screen'' tries to emulate as much of the
-VT100/ANSI standard as possible. But if your terminal lacks
-certain capabilities, the emulation may not be complete. In
-these cases ''screen'' has to tell the applications that
-some of the features are missing. This is no problem on
-machines using termcap, because ''screen'' can use the
-$TERMCAP variable to customize the standard ''screen''
-termcap.
-
-
-But if you do a rlogin on another machine or your machine
-supports only terminfo this method fails. Because of this,
-''screen'' offers a way to deal with these cases. Here is
-how it works:
-
-
-When ''screen'' tries to figure out a terminal name for
-itself, it first looks for an entry named
-``screen.
-''screen'' tries ``screen'' (or ``screen-w'' if the
-terminal is wide (132 cols or more)). If even this entry
-cannot be found, ``vt100'' is used as a
-substitute.
-
-
-The idea is that if you have a terminal which doesn't
-support an important feature (e.g. delete char or clear to
-EOS) you can build a new termcap/terminfo entry for
-''screen'' (named ``screen.
-''Screen'' also sets the $TERMCAP variable reflecting the
-capabilities of the virtual terminal emulated. Notice that,
-however, on machines using the terminfo database this
-variable has no effect. Furthermore, the variable $WINDOW is
-set to the window number of each window.
-
-
-The actual set of capabilities supported by the virtual
-terminal depends on the capabilities supported by the
-physical terminal. If, for instance, the physical terminal
-does not support underscore mode, ''screen'' does not put
-the `us' and `ue' capabilities into the window's $TERMCAP
-variable, accordingly. However, a minimum number of
-capabilities must be supported by a terminal in order to run
-''screen''; namely scrolling, clear screen, and direct
-cursor addressing (in addition, ''screen'' does not run
-on hardcopy terminals or on terminals that
-over-strike).
-
-
-Also, you can customize the $TERMCAP value used by
-''screen'' by using the ``termcap'' .screenrc command, or
-by defining the variable $SCREENCAP prior to startup. When
-the is latter defined, its value will be copied verbatim
-into each window's $TERMCAP variable. This can either be the
-full terminal definition, or a filename where the terminal
-``screen'' (and/or ``screen-w'') is defined.
-
-
-Note that ''screen'' honors the ``terminfo'' .screenrc
-command if the system uses the terminfo database rather than
-termcap.
-
-
-When the boolean `G0' capability is present in the termcap
-entry for the terminal on which ''screen'' has been
-called, the terminal emulation of ''screen'' supports
-multiple character sets. This allows an application to make
-use of, for instance, the VT100 graphics character set or
-national character sets. The following control functions
-from ISO 2022 are supported: ''lock shift G0''
-(''SI''), ''lock shift G1'' (''SO''), ''lock shift
-G2'', ''lock shift G3'', ''single shift G2'', and
-''single shift G3''. When a virtual terminal is created
-or reset, the ASCII character set is designated as ''G0''
-through ''G3''. When the `G0' capability is present,
-''screen'' evaluates the capabilities `S0', `E0', and
-`C0' if present. `S0' is the sequence the terminal uses to
-enable and start the graphics character set rather than
-''SI''. `E0' is the corresponding replacement for
-''SO''. `C0' gives a character by character translation
-string that is used during semi-graphics mode. This string
-is built like the `acsc' terminfo capability.
-
-
-When the `po' and `pf' capabilities are present in the
-terminal's termcap entry, applications running in a
-''screen'' window can send output to the printer port of
-the terminal. This allows a user to have an application in
-one window sending output to a printer connected to the
-terminal, while all other windows are still active (the
-printer port is enabled and disabled again for each chunk of
-output). As a side-effect, programs running in different
-windows can send output to the printer simultaneously. Data
-sent to the printer is not displayed in the window. The
-''info'' command displays a line starting `PRIN' while
-the printer is active.
-
-
-''Screen'' maintains a hardstatus line for every window.
-If a window gets selected, the display's hardstatus will be
-updated to match the window's hardstatus line. If the
-display has no hardstatus the line will be displayed as a
-standard ''screen'' message. The hardstatus line can be
-changed with the ANSI Application Program Command (APC):
-``ESC_
-''
-
-
-Some capabilities are only put into the $TERMCAP variable of
-the virtual terminal if they can be efficiently implemented
-by the physical terminal. For instance, `dl' (delete line)
-is only put into the $TERMCAP variable if the terminal
-supports either delete line itself or scrolling regions.
-Note that this may provoke confusion, when the session is
-reattached on a different terminal, as the value of $TERMCAP
-cannot be modified by parent processes.

-
-
-In order to do a full VT100 emulation ''screen'' has to
-detect that a sequence of characters in the input stream was
-generated by a keypress on the user's keyboard and insert
-the VT100 style escape sequence. ''Screen'' has a very
-flexible way of doing this by making it possible to map
-arbitrary commands on arbitrary sequences of characters. For
-standard VT100 emulation the command will always insert a
-string in the input buffer of the window (see also command
-__stuff__ in the command table). Because the sequences
-generated by a keypress can change after a reattach from a
-different terminal type, it is possible to bind commands to
-the termcap name of the keys. ''Screen'' will insert the
-correct binding after each reattach. See the __bindkey__
-command for further details on the syntax and
-examples.
-
-
-Here is the table of the default key bindings. (A) means
-that the command is executed if the keyboard is switched
-into application mode.

-!!SPECIAL TERMINAL CAPABILITIES
-
-
-The following table describes all terminal capabilities that
-are recognized by ''screen'' and are not in the
-termcap(5) manual. You can place these capabilities in your
-termcap entries (in `/etc/termcap') or use them with the
-commands `termcap', `terminfo' and `termcapinfo' in your
-screenrc files. It is often not possible to place these
-capabilities in the terminfo database.
-
-
-__LP__ ''(bool)''
-
-
-Terminal has VT100 style margins (`magic margins'). Note
-that this capability is obsolete because ''screen'' uses
-the standard 'xn' instead.
-
-
-__Z0__ ''(str)''
-
-
-Change width to 132 columns.
-
-
-__Z1__ ''(str)''
-
-
-Change width to 80 columns.
-
-
-__WS__ ''(str)''
-
-
-Resize display. This capability has the desired width and
-height as arguments. ''!SunView(tm)'' example:
-'E[[8;%d;%dt'.
-
-
-__NF__ ''(bool)''
-
-
-Terminal doesn't need flow control. Send ^S and ^Q direct to
-the application. Same as 'flow off'. The opposite of this
-capability is 'nx'.
-
-
-__G0__ ''(bool)''
-
-
-Terminal can deal with ISO 2022 font selection
-sequences.
-
-
-__S0__ ''(str)''
-
-
-Switch charset 'G0' to the specified charset. Default is
-'E(%.'.
-
-
-__E0__ ''(str)''
-
-
-Switch charset 'G0' back to standard charset. Default is
-'E(B'.
-
-
-__C0__ ''(str)''
-
-
-Use the string as a conversion table for font ''. See the
-'ac' capability for more details.
-
-
-__CS__ ''(str)''
-
-
-Switch cursor-keys to application mode.
-
-
-__CE__ ''(str)''
-
-
-Switch cursor-keys back to normal mode.
-
-
-__AN__ ''(bool)''
-
-
-Turn on autonuke. See the 'autonuke' command for more
-details.
-
-
-__OL__ ''(num)''
-
-
-Set the output buffer limit. See the 'obuflimit' command for
-more details.
-
-
-__KJ__ ''(str)''
-
-
-Set the encoding of the terminal. See the 'encoding' command
-for valid encodings.
-
-
-__AF__ ''(str)''
-
-
-Change character foreground color in an ANSI conform way.
-This capability will almost always be set to 'E[[3%dm'
-('E[[3%p1%dm' on terminfo machines).
-
-
-__AB__ ''(str)''
-
-
-Same as 'AF', but change background color.
-
-
-__AX__ ''(bool)''
-
-
-Does understand ANSI set default fg/bg color (E[[39m /
-E[[49m).
-
-
-__XC__ ''(str)''
-
-
-Describe a translation of characters to strings depending on
-the current font. More details follow in the next
-section.
-
-
-__XT__ ''(bool)''
-
-
-Terminal understands special xterm sequences (OSC, mouse
-tracking).
-
-
-__C8__ ''(bool)''
-
-
-Terminal needs bold to display high-intensity colors (e.g.
-Eterm).
-
-
-__TF__ ''(bool)''
-
-
-Add missing capabilities to the termcap/info entry. (Set by
-default).
-!!CHARACTER TRANSLATION
-
-
-''Screen'' has a powerful mechanism to translate
-characters to arbitrary strings depending on the current
-font and terminal type. Use this feature if you want to work
-with a common standard character set (say ISO8851-latin1)
-even on terminals that scatter the more unusual characters
-over several national language font pages.
-
-
-Syntax:
-
-
-__ XC=__''''{__,,__''''}
-'' '' := ''''{__,__''''}
-'' '' := ''
-''The things in braces may be repeated any number of times.
-
-
-A '''' tells ''screen'' how to
-map characters in font '''' ('B':
-Ascii, 'A': UK, 'K': german, etc.) to strings. Every
-'''' describes to what string a single
-character will be translated. A template mechanism is used,
-as most of the time the codes have a lot in common (for
-example strings to switch to and from another charset). Each
-occurrence of '%' in '''' gets
-substituted with the '''' specified
-together with the character. If your strings are not similar
-at all, then use '%' as a template and place the full string
-in ''''. A quoting mechanism was
-added to make it possible to use a real '%'. The ''
-character quotes the special characters '', '%', and
-','.
-
-
-Here is an example:
-
-
-termcap hp700 'XC=BE(K%E(B,304[[,326\\,334]'
-
-
-This tells ''screen'' how to translate ISOlatin1 (charset
-'B') upper case umlaut characters on a hp700 terminal that
-has a german charset. '304' gets translated to 'E(K[[E(B' and
-so on. Note that this line gets parsed *three* times before
-the internal lookup table is built, therefore a lot of
-quoting is needed to create a single ''.
-
-
-Another extension was added to allow more emulation: If a
-mapping translates the unquoted '%' char, it will be sent to
-the terminal whenever ''screen'' switches to the
-corresponding ''''. In this special
-case the template is assumed to be just '%' because the
-charset switch sequence and the character mappings normally
-haven't much in common.
-
-
-This example shows one use of the extension:
-
-
-termcap xterm 'XC=K%,%E(B,[[304,\\326,]334'
-
-
-Here, a part of the german ('K') charset is emulated on an
-xterm. If ''screen'' has to change to the 'K' charset,
-'E(B' will be sent to the terminal, i.e. the ASCII charset
-is used instead. The template is just '%', so the mapping is
-straightforward: '[[' to '304', '' to '326', and ']' to
-'334'.

-!!VERSION
-
-
-This is version 3.9.9. Its roots are a merge of a custom
-version 2.3PR7 by Wayne Davison and several enhancements to
-Oliver Laumann's version 2.. Note that all versions
-numbered 2.x are copyright by Oliver Laumann.
-!!AVAILABILITY
-
-
-The latest official release of ''screen'' available via
-anonymous ftp from gnudist.gnu.org, nic.funet.fi or any
-other ''GNU'' distribution site. The home site of
-''screen'' is ftp.uni-erlangen.de, in the directory
-pub/utilities/screen. The subdirectory `private' contains
-the latest beta testing release. If you want to help, send a
-note to screen@uni-erlangen.de.
-!!BUGS
-
-
-`dm' (delete mode) and `xs' are not handled correctly (they
-are ignored). `xn' is treated as a magic-margin
-indicator.
-
-
-''Screen'' has no clue about double-high or double-wide
-characters. But this is the only area where ''vttest'' is
-allowed to fail.
-
-
-It is not possible to change the environment variable
-$TERMCAP when reattaching under a different terminal
-type.
-
-
-The support of terminfo based systems is very limited.
-Adding extra capabilities to $TERMCAP may not have any
-effects.
-
-
-''Screen'' does not make use of hardware
-tabs.
-
-
-''Screen'' must be installed as set-uid with owner root
-on most systems in order to be able to correctly change the
-owner of the tty device file for each window. Special
-permission may also be required to write the file
-``/var/run/utmp''.
-
-
-Entries in ``/var/run/utmp'' are not removed when
-''screen'' is killed with SIGKILL. This will cause some
-programs (like
-''
-
-
-''Screen'' may give a strange warning when your tty has
-no utmp entry.
-
-
-When the modem line was hung up, ''screen'' may not
-automatically detach (or quit) unless the device driver is
-configured to send a HANGUP signal. To detach a
-''screen'' session use the -D or -d command line
-option.
-
-
-If a password is set, the command line options -d and -D
-still detach a session without asking.
-
-
-Both ``breaktype'' and ``defbreaktype'' change the break
-generating method used by all terminal devices. The first
-should change a window specific setting, where the latter
-should change only the default for new windows.
-
-
-When attaching to a multiuser session, the user's .screenrc
-file is not sourced. Each user's personal settings have to
-be included in the .screenrc file from which the session is
-booted, or have to be changed manually.
-
-
-A weird imagination is most useful to gain full advantage of
-all the features.
