You write code for a living, and your inherit a legacy program written in perl.
Tutorial Details:
You can program in your native language in your sleep. But you don't know perl at all, or you've only dabbled with it. Your deadline doesn't give you enough time to rewrite the legacy program in your native language, but it needs new features. You need to learn perl, and you need to learn it NOW. "Impatient Perl" was written for you.
The Impatient Introduction to Perl
This document is for people who either want to learn perl or are already programming in perl and just do not have the patience to scrounge for information to learn and use perl. This document should also find use as a handy desk reference for some of the more common perl related questions.
The history of perl in 100 words or less
In the mid 1980s, Larry Wall was working as a sys-admin and found that he needed to do a number of common, yet oddball functions over and over again. And he did not like any of the scripting languages that were around at the time, so he invented Perl. Version 1 was released circa 1987. A few changes have occurred between then and now. The current version of Perl has exceeded 5.8.0 and is a highly recommended upgrade.
Cheap Reference Material
"Programming Perl" by Larry Wall, Tom Christiansen, and Jon Orwant. Highly recommended book to have handy at all times. It is sometimes referred to as the "Camel Book" by way of the camel drawing on its cover. The publisher, O'Reilly, has printed enough computer books to choke a, well, camel, and each one has a different animal on its cover. Therefore if you hear reference to some animal book, it is probably an O'Reilly book. Well, unless its the "Dragon Book", because that refers to a book called "Compilers" by Aho, Sethi, and Ullman. Anyways, when I get a graphic that I like, I will slap it on the front cover and give this document a picture name as well.
