About chsh

chsh changes a user's login shell.

Valid Shells

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.

It can also be configured to accept only shells listed in this file (unless the user is root). If a shell is not specified, chsh will prompt for one to be specified.
