You mean write one completely from scratch? I can't imagine why you would want to...there are many other shells beyond Bash if you are looking for a feature that Bash doesn't have.

But if you did want to write your own, the best thing to do would be to start studying the source code of existing shells and learning how things are done. You can then build on top of that or modify it to do whatever it is you want in the first place. It is open source, after all.

you can have anything as your shell,
look in /etc/passwd

shows the login shell, you can login with anything you like

it may be of limited use though

Aaaah, my eyes!!!

Back to the point at hand. If you want to change your default shell use the command

Code:

chsh

To change your shell. You will need to ensure that you have additional shells installed.

http://ftp.gnu.org/pub/gnu/bash/bash-3.2.tar.gz

A quick google of "bash source" gave me that as the first hit.
