Not sure if it's completely comprehensive, but the clearest tutorial/reference of regex's that I've used is in the book "The AWK Programming Language" by Aho, Kernighan, Weinberger.

That is a nice introduction indeed. Afterwards, to get a taste for more complex matching, maybe the Perl / PCRE docs.
