This is the authoritative guide to the hottest new UNIX utility in years, coauthored by its creator, Larry Wall. Perl is a language for easily manipulating text, files, and processes. Perl provides a more concise and readable way to do many jobs that were formerly accomplished (with difficulty) by programming in the C language or one of the shells. Even though Perl is not yet a standard part of UNIX, it is likely to be available wherever you choose to work. And if it isn't, you can get it and install it easily and free of charge. Contents include: An introduction to Perl Common tasks with Perl Real Perl programs; includes database manipulation, programming aids, system administration, text and filename manipulation, interprocess communication, and more Perl syntax Perl functions Other oddments; invocation options, debugging, efficiency, the Perl library, linking in C subroutines, etc. Also includes a pull-out quick-reference card (designed and created by Johan Vromans).

The Perl Cookbook is a comprehensive collection of problems, solutions, and practical examples for anyone programming in Perl. Topics range from beginner questions to techniques that even the most experienced of Perl programmers will learn from. More than just a collection of tips and tricks, the Perl Cookbook is the long-awaited companion volume to Programming Perl, filled with previously unpublished Perl arcana.The Perl Cookbook contains thousands upon thousands of examples ranging from brief one-liners to complete applications. Covered topic areas spread across nearly four hundred separate "recipes," These recipes were rigorously reviewed by scores of the best minds inside and outside Perl, foremost of which was Larry Wall, the creator of Perl himself.The Perl Cookbook is written by Tom Christiansen, Perl evangelist and coauthor of the bestselling Programming Perl and Learning Perl ; and Nathan Torkington, Perl trainer and co-maintainer of the Perl Frequently Asked Questions list.

This guide is tailored for those seeking a quick, practical understanding of Perl, a public domain language that has become the leading UNIX scripting language, gradually expanding into non-UNIX environments. Perl is a high-level, multi-purpose language utilized in various system administration tasks and other applications, including data reduction, report generation, distributed computing, and software development. Its versatility allows programmers to consolidate functions typically spread across different tools and languages, such as shell, sed, awk, and C, into a single script, making it a powerful and flexible option. Written by a prominent Perl instructor, this resource offers a systematic, step-by-step tutorial approach to mastering the language. It features numerous short code examples within a relaxed, informal, and clear explanation of the main features. Each chapter includes exercise problems with solutions, ensuring that readers who engage with the content will gain a broad and productive command of Perl. For those interested in advanced programming techniques, a companion guide is available for further exploration of the language's capabilities.

Perl ist eine Skriptsprache zur einfachen Bearbeitung von Texten, Dateien und Prozessen. Das Buch macht mit häufig verwendeten Operationen und Sprachmerkmalen, so wie sie in den meisten Perl-Programmen zu finden sind, bekannt. Bei der Einführung von Perl werden im Buch folgende Themen behandelt: Skalare Daten, Kontrollstrukturen, Ein- und Ausgabe, Reguläre Ausdrücke, Funktionen, Dateihandles, Formate, Verwaltung von Dateien, Verzeichnissen und Prozessen, Zugriff auf Datenbanken und CGI-Programmierung. Seine Leistungsfähigkeit hat Perl besonders bei der Systemadministration und der Web-Programmierung bewiesen. Perl ist leicht installierbar und läuft unter UNIX, MS-DOS, VMS, OS/2, Plan 9, Macintosh und unter jeder Windows-Variante.
