CHSH(1)                       User Commands                      CHSH(1)

NAME         top

       chsh - change login shell

SYNOPSIS         top


       chsh [options] [LOGIN]

DESCRIPTION         top

       The chsh command 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 superuser
       may change the login shell for any account.

OPTIONS         top

       The options which apply to the chsh command are:

       -h, --help
           Display help message and exit.

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the
           configuration files from the CHROOT_DIR directory. Only
           absolute paths are supported.

       -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         top

       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.

FILES         top

       /etc/passwd
           User account information.

       /etc/shells

       /etc/login.defs
           Shadow password suite configuration.
