What is "normal shell"?  Bash?  What version?  Are you on a single-user
system you set up yourself, or are you at a school or business where an
administrator has pre-configured the "normal shell"?

Also, chsh has different syntax on different OS's:  On MacOS it's an
alias for chpass; on Ubuntu it only has --help and --shell options
(and their -h -s counterparts); on RHEL it has several options and
uses -u instead of -h for --help, and adds -l for --list, both of
which conflict with chpass on MacOs; and so on.  So "please fix" is
a rather open-ended request.

Oh well, never mind.  Here's something for RHEL; perhaps you can figure
out how to fix it for your local environment, or just remove everything
except -s, given that's the one thing they all seem to have in common.

Maybe somebody else can remind me if there's an easier way to indicate
to _arguments that all the arguments are mutually exclusive.  (RedHat
chsh accepts more than one but only uses the first one it encounters.)
