Learning Perl

Learning Perlis 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,sedandawk. 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,sed,awk, various other UNIX utilities, and C programs. With this breadth of capability, Perl is an extraordinarily powerful and flexible language.

Learning Perl, 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,Programming Perl.

About the author (1993)

Randal L. Schwartz is a two-decade veteran of the software industry. He is skilled in software design, system administration, security, technical writing, and training. Randal has coauthored the "must-have" standards: Programming Perl, Learning Perl, Learning Perl for Win32 Systems, and Effective Perl Learning, and is a regular columnist for WebTechniques, PerformanceComputing, SysAdmin, and Linux magazines. He is also a frequent contributor to the Perl newsgroups, and has moderated comp.lang.perl.announce since its inception. His offbeat humor and technical mastery have reached legendary proportions worldwide (but he probably started some of those legends himself). Randal's desire to give back to the Perl community inspired him to help create and provide initial funding for The Perl Institute. He is also a founding board member of the Perl Mongers (perl.org), the worldwide Perl grassroots advocacy organization. Since 1985, Randal has owned and operated Stonehenge Consulting Services, Inc. Randal can be reached for comment at merlyn@stonehenge.com or (503) 777-0095, and welcomes questions on Perl and other related topics.
