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

The chsh command is part of the util-linux package which can be downloaded from Linux Kernel Archive <https://www.kernel.org/pub/linux/utils/util-linux/>.
