Ah, great, thanks, Tony! I know some of the old Unix shell commands can do
really neat things, but i tend to forget about them, I didn't "grow up"
with them. If there hadn't been any feedback I would have resorted to
coding this in Perl, much of a waste of time.

It helps in comparing between machines. And it helps much when you
transfer users from one machine to another. I just snip them out in the
relevant files and add them on the other machine. Usually something like
all users above uid 10000 or so. If the list isn't sorted it's a bit
harder to do that.
