chsh - change your login shell

chsh [*-s* /shell/] [*-l*] [*-h*] [*-v*] [/username/]

chsh is used to change your login shell. If a shell is not given on the command line, chsh prompts for one.

chsh supports non-local entries (kerberos, LDAP, etc.) if linked with libuser, otherwise use *ypchsh*(1), *lchsh*(1) or any other implementation for non-local entries.

-s, –shell shell

Specify your login shell.

-l, –list-shells

Print the list of shells listed in /etc/shells and exit.

-h, –help

Display help text and exit.

-v, –version

Display version information and exit.

chsh will accept the full pathname of any executable file on the system.

The default behavior for non-root users is to accept only shells listed in the /etc/shells file, and issue a warning for root user. It can also be configured at compile-time to only issue a warning for all users.

Returns 0 if operation was successful, 1 if operation failed or command syntax was not valid.

*login*(1), *login.defs*(5), *passwd*(5), *shells*(5)
