Another book that's well worth reading is ``Unix Text Processing''
by Dale Dogherty and Tim O'Reilly.  It has excellent information
on many *nix utilities including about the only thing I ever
understood on using the advanced features of ``sed'' (which I didn't
need much after learning perl :-).

There's a pretty good section on regular expressions in the
chapter on ``vi''.  Perl regular expressions have a fair number
of extensions since this was written (e.g. \d as shorthand for
the digits [0-9], etc.), but I still found this helpful.

This book is available for free download from O'Reilly.
