Perl by Example, Fifth Edition, is the proven, easy way to master Perl 5 programming. Legendary Silicon Valley programming instructor Ellie Quigley has fully updated and focused her classic text on today’s key Perl applications, especially automation, testing, data extraction, and legacy code maintenance. She has also revised this edition to reflect “modern Perl” practices that have emerged since Perl 5.10.

Quigley illuminates every technique with focused, classroom-tested code examples. For each example, she shows you code, input, and output, and provides detailed, line-by-line explanations of how the code generates that output. And her coverage is comprehensive, from basic syntax to regular expression handling, files, references, objects, working with databases, and much more…plus appendices that contain a complete list of functions and definitions, command-line switches, special variables, and popular modules.

More than 50,000 sysadmins, power users, and developers have used this book’s previous editions to become expert Perl programmers, and you can, too–even if you’re completely new to Perl. Then, once you’re an expert, you’ll routinely return to this practical guide as the best source for reliable answers, solutions, and code. A more focused, quicker read than ever, this clear and practical guide will take you from your first Perl script to advanced applications. It’s the only Perl text you’ll need.
