CHSH(1)                          User Commands                         CHSH(1)

NAME
       chsh - change login shell
SYNOPSIS
       chsh [options] [LOGIN]
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 her own account, the super user may change the login shell
       for any account.
OPTIONS
       The options which apply to the chsh command are:
       -h, --help
          Display help message and exit.
       -s, --shell SHELL
          The name of the user's new login shell. Setting this field to blank
          causes the system to select the default login shell.
       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 shell, or leave the line blank to use the current
       one. The current shell is displayed between a pair of [ ] marks.
NOTE
       The only restriction 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 her 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 ever changing her login
       shell back to its original value.
