chsh

Change shell

$ chsh -s [path/to/shell_binary] [username]

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

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 and is available from https://www.kernel.org/pub/linux/utils/util-linux/.

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,--shellshell 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. However, it will issue a warning if the shell is not listed in the /etc/shells file. On the other hand, it can also be configured such that it will only accept shells listed in this file, unless you are root.
