Presents guidelines on the art of coding with Perl, covering such topics as references and scoping, object-oriented programing, writing and using modules, testing Perl code, and contributing to CPAN.

Introduces the programming language to beginners and provides a Perl language reference for experienced users, covering operators, statements, formats, modules, objects, threads, tied variables, debugging, and security

Shows how to write, debug, and run a Perl program, describes CGI scripting and data manipulation, and describes scalar values, basic operators, and associative arrays

In this smooth, carefully paced course, leading Perl trainers and a Windows NT practitioner teach you to program in the language that promises to emerge as the scripting language of choice on NT. With a foreword by Larry Wall, the creator of Perl, this book is the "official" guide for both formal (classroom) and informal learning. Based on the "llama book," Learning Perl on Win32 Systems features tips for PC users and new NT-specific examples. Perl for Win32 is a language for easily manipulating text, files, user and group profiles, performance and event logs, and registry entries, and a distribution is available on the Windows NT Resource Kit. Peer-to-peer technical support is now available on the perl.win32.users mailing list. The contents Erik Olson is director of advanced technologies for Axiom Technologies, LC, where he specializes in providing Win32 development solutions. Randal L. Schwartz and Tom Christiansen have also written Programming Perl , co-authored with Larry Wall and published by O'Reilly & Associates.

<i>Learning Perl</i> is designed for those who seek a rapid working knowledge of Perl. A public domain language, Perl has established itself as the premier UNIX scripting language--replacing facilities such as the shell, <i>sed</i> and <i>awk</i>. It is currently taking root in non-UNIX markets as well. Perl is a high-level, multi-purpose language. It is used in diverse system administration tasks, while also playing an endless variety of roles in other areas. These range from data reduction and report generation to distributed computing and assorted auxiliary roles in software development. Perl has even encroached upon the territory of C and other programming languages. Perl allows the programmer to combine in one script functions that previously had to be divided between the shell, <i>sed</i>, <i>awk</i>, various other UNIX utilities, and C programs. With this breadth of capability, Perl is an extraordinarily powerful and flexible language. <i>Learning Perl</i>, written by a leading Perl instructor, provides a systematic, step-by-step, tutorial approach to learning the language. There are numerous short code examples punctuating a relaxed, informal, and precise tour of all the main features of the language. In addition, each chapter contains exercise problems, together with their solutions. Anyone who works through the book will be capable of programming with a broad and productive range of Perl features. For a comprehensive and detailed guide to advanced programming with Perl, read O'Reilly's companion book, <i>Programming Perl</i>.

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.
