Have you tried searching for an online regexp reference, or used a 
regexp book? If so, which one?

Things like "how to match a digit or asterisk" and "how to match a 
space" should be easy to find there.

Also: are you actually trying to do this with grep/egrep? Or do you want 
to write something in ruby?
