In my search to exploit the world of Perl these are a few good perl tutorials I came across :
Learn Perl in 10 easy lessons : Guides you through the important aspects of perl in a nice and simple way. But only 6 lessons are available out of the 10. If all lessons were there you wouldn’t need any other tutorial.
Perl Tutorial by Nik Silver : A historic perl tutorial. But it’s good to learn the basics.
Essential Perl: Someone with programming experience should take a look at this. Good for someone in a hurry and is used to programming.
