NAME    [Toc]    [Back]

       chsh - change login shell

SYNOPSIS    [Toc]    [Back]

       chsh [-s login_shell] [user]

DESCRIPTION    [Toc]    [Back]

       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 superuser,
 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 current 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.
