If you plan on doing a lot of Perl programming, I'd recommend picking the camel book for sure. Also, there's a few more books I'd have on my bookshelf.
- Perl Debugged - Nice easy to follow text on things to watch out for
- Effective Perl Programming - for when you're feet are a bit more wet. It's also an excelllent debugging reference
- Perl Black Book - unfortunately it's currently out of print but I picked up a couple more copies on half.com
- The Perl Cookbook - similar to the black book and again an excellent reference for "recipies" in Perl
And the one other thing I would be lost without is the Perl TK Debugger. It's a GUI debugger that works on Linux or windows, it's free and you can get a copy here.
Hopefully that will give you some help!
There is no emoticon for what I'm feeling now.
