Impatient Perl

This free perl book is for people who either want to learn perl or are already programming in perl and just don’t 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.

Book Description

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 5.8.3 and is a highly recommended upgrade.

Perl 6 is on the drawing board as a fundamental rewrite of the language. It is not available yet, and probably will not be available for some time.
