it, and for instance, certain database softwares will require that either
csh or ksh be the login shell.

I see the point: bash tends to be associated with Linux. However, you may
run bash on pretty much any *nix.

FreeBSD defaults to csh, OpenBSD and NetBSD to ksh.

Easier than to pronounce: chsh.

That's why well-written scripts start with a
SheBang<http://en.wikipedia.org/wiki/Shebang_(Unix)>:
rule of scriptisation #287, never assume anything about the environment
your script will run on.
