Tinkering with Perl is a free book that provides an introduction to programming in Perl, as well as a basic reference for things like foreach in Perl, if-then, and if-then-else, in addition to providing a glossary where you can find definitions for concatenate and other terms.
Tinkering with Perl may be one of the most popular offerings on this site, but it's not the only attraction. You can read a tongue-in-cheek Game Review: Meatspace, read an even more offbeat customer service survey (whether or not you actually fill it out), and spend a few minutes wishing your boss would read, The Administrator Who Cried, "Important!" (Not to mention that there are other things you can read here besides tech stuff, from Janra Ball: The Headache to The Spectacles.)
