Seriously, I love perl, someone can indicate me good tuts?
http://perl-tutorial.org/ perl tutorials.
I am partial towards: http://perl101.org/
If you want to buy a book, I prefer: http://www.amazon.com/Perl-Black-Book-Comprehensive-Reference/dp/1576104656
Both of those references seem rather out of date. The online tutorial mentions Perl 5.8.6 and the book was published in 1999.
I recommend that you start recommending some more up to date material :-)
I blog about Perl and I love that language :)
