OK, thanks, then I should be covered. > 'man perlre' (perl regular expressions) is a good reference in > most cases; more so if you're actually using perl, of course. It's been a long time since I used perl regularly, but it might come in handy as an online reference. Are perl regular expressions "compatible" with the ones used by grep/sed/awk, etc?

I'm most interested in learning how to write portable code anyways, so these should be a good start. > "Learning Perl" and "The Perl Cookbook" are good for Perl; you > might want "UNIX System Administration", but you'll definitely > want "The Debian Administrator's Handbook" at > http://debian-handbook.info I actually also found "Learning Perl", and I think I have the Cookbook if I dig a little deeper, but I've more or less settled on learning C, as I think that would be more worthwhile. Downloaded the Debian book, though, I'll have to look through it and print out some of the chapters. Thanks for the advice! :) Petter -- "I'm ionized" "Are you sure?" "I'm positive."
