chsh - Man Page

• Change the user's login shell: chsh -s path/to/shell_binary username

tldr.sh

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, lchsh 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.
