CHSH(H)                                                   CHSH(H)



NAME
       chsh - change login shell

SYNOPSIS
       chsh [-s login_shell] [user]

DESCRIPTION
       chsh  changes  the  user login shell.  This determines the
       name of the user's initial login command.  A  normal  user
       may only change the login shell for their own account, the
       super user may change the login shell for any account.

       The only restrictions placed on the login  shell  is  that
       the command name must be listed in /etc/shells, unless the
       invoker is the super-user,  and  then  any  value  may  be
       added.   An  account with a restricted login shell may not
       change  their  login  shell.   For  this  reason,  placing
       /bin/rsh  in /etc/shells is discouraged since accidentally
       changing to a restricted shell would prevent the user from
       every  changing  their  login  shell  back to its original
       value.

       If the -s option is not  selected,  chsh  operates  in  an
       interactive  fashion,  prompting the user with the current
       login shell.  Enter the new value to change the field,  or
       leave  the  line blank to use the current value.  The cur-
       rent value is displayed between a pair of [ ] marks.

       The  file,  /etc/login.defs,  defines  some  configuration
       options  that  affects  how  chsh operates, especially for
       non-root users.
