__NAME__


ul - do underlining
__SYNOPSIS__


ul [[-i] [[-t terminal] [[name ...]
__DESCRIPTION__


Ul reads the named files (or standard input if none are
given) and translates occurrences of underscores to the
sequence which indicates underlining for the terminal in
use, as specified by the environment variable TERM.
The file /etc/termcap is read to determine the
appropriate sequences for underlining. If the terminal is
incapable of underlining, but is capable of a standout mode
then that is used instead. If the terminal can overstrike,
or handles underlining automatically, ul degenerates to
cat(1). If the terminal cannot underline,
underlining is ignored.


The following options are available:
       -i   Underlining is indicated by a separate line  contain-ing  appropriate  dashes `-'; this is useful when youwant to look at the underlining which is  present  inan nroff
output stream on a crt-terminal.


-t terminal
Overrides the terminal type specified in the environ- ment with terminal.


__ENVIRONMENT__


The following environment variable is used:
       TERM


The TERM variable is used to relate a tty device
with its device capability description (see
termcap(5)). TERM is set at login time,
either by the default termi- nal type specified in
/etc/ttys or as set during the login process by the
user in their login file (see
environ(7)).


__SEE ALSO__


colcrt(1), man(1),
nroff(1)
__BUGS__


The nroff(1) command usually outputs a series of
backspaces and underlines intermixed with the text to
indicate under- lining. No attempt is made to optimize the
backward motion.
__HISTORY__


The ul command appeared in 3.0 BSD
.
