The World’s Easiest Perl 5 Tutorial–Updated for Today’s Applications and “Modern Perl” Best Practices
“When I look at my bookshelf, I see eleven books on Perl programming. Perl by Example, Third Edition, isn’t on the shelf; it sits on my desk, where I use it almost daily. I still think it is the best Perl book on the market for anyone–beginner or seasoned programmer–who uses Perl daily”
–Bill Maples, Enterprise Network Support, Fidelity National Information Services
Perl by Example, Fifth Edition, is the easiest, most hands-on way to master the newest versions of Perl 5.x. 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. Every section also contains an up-to-date “Perl Gotchas” section, helping you anticipate, avoid, and overcome common problems.
