Perl by Example, Fifth Edition, is the easiest, most hands-on way to learn Perl. Legendary Silicon Valley programming instructor Ellie Quigley has thoroughly updated and condensed her classic to focus on the applications and skills today's Perl users care about most: from system task automation, data extraction, and testing through legacy code maintenance and CPAN. Quigley illuminates every technique with focused, classroom-tested code examples, detailed explanations, and real program output. She shows the code, the input and output, and provides detailed, line-by line explanations of how the code generates that output.
