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