Hi guys,
That was what I was looking for, thank you very much.

It's brought up one other question I have though, from the passwd file, the lines output in a way like this:
demos::993:997

emonstration User:/usr/demos:/bin/csh
OutOfBox::995:997:Out of Box Experience:/usr/people/tour:/bin/csh
As you can see, those don't have passwords, but what part of the lines is the username?
Thanks ever so much again.
hellz.
