Larry Wall Libros

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).

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.
