CHSH(1) User Commands CHSH(1)
chsh - change login shell
chsh [options] [LOGIN]
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.
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.
-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.
The only restriction 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 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.
/etc/passwd
User account information.
/etc/shells
List of valid login shells.
/etc/login.defs
Shadow password suite configuration.
chfn(1), login.defs(5), passwd(5).
