chsh is used to change your login shell.
If a shell is not given on the command line,
chsh prompts for one.
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.
On the other hand, it can also be configured such that it will
only accept shells listed in this file, unless you are root.
