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.
OPTIONS
-s, --shell
Specify your login shell.
-l, --list-shells
Print the list of shells listed in
/etc/shells
and exit.
