Perl ("Practical Extraction and Report Language" - although the acronym was devised long
after the name was chosen) is a programming language devised by Larry Wall and first released in
1987. Although a
general purpose programming language, Perl has become most popular for string/text
manipulation, for server-side web applications (often implemented using a web server's the CGI interface),
and system administration tasks.
The Perl language itself is distributed under both the
GPL and the
Artistic license, although
programs and libraries written in Perl are distributed under a wide variety of different licenses.

Perl is the language for people who want to get work done. Originally targeted to sysadmins for heavy-duty text processing, Perl is now a full-featured programming language suitable for almost any task on almost any platform-from short fixes on the command line to web applications, bioinformatics, finance, and much more. Other books may teach you to program in Perl, but this book will turn you into a Perl programmer.
Perl is a powerful programming language that has grown in popularity since it first appeared in 1988. The first edition of this book, Programming Perl, hit the shelves in 1990, and was quickly adopted as the undisputed bible of the language. Since then, Perl has grown with the times, and so has this book.
Programming Perl is not just a book about Perl. It is also a unique introduction to the language and its culture, as one might expect only from its authors. Larry Wall is the inventor of Perl, and provides a unique perspective on the evolution of Perl and its future direction. Tom Christiansen was one of the first champions of the language, and lives and breathes the complexities of Perl internals as few other mortals do. Jon Orwant is the editor of The Perl Journal, which has brought together the Perl community as a common forum for new developments in Perl.
Any Perl book can show the syntax of Perl's functions, but only this one is a comprehensive guide to all the nooks and crannies of the language. Any Perl book can explain typeglobs, pseudohashes, and closures, but only this one shows how they really work. Any Perl book can say that my is faster than local, but only this one explains why. Any Perl book can have a title, but only this book is affectionately known by all Perl programmers as "The Camel."
This third edition of Programming Perl has been expanded to cover version 5.6 of this maturing language. New topics include threading, the compiler, Unicode, and other new features that have been added since the previous edition.
When it comes to learning Perl, programmers consider this book to be the undisputed bible. You not only learn every nuance of this language, you also get a unique perspective on the evolution of Perl and its future direction. The 4th edition has been thoroughly updated for version 5.14, with details on regular expressions, support for UNICODE, threads, and many other features.
Many Perl books explain typeglobs, pseudohashes, and closures, but only this one shows the motivations behind these features and why they work the way they do. It's exactly what you'd expect from its prominent authors: Larry Wall is the inventor of Perl, and Tom Christiansen was one of the first champions of the language.
In print since 1991, the book affectionately known as "the Camel" has played a central role in computing among programmers and system administrators around the world. With Programming Perl, you too will learn the most efficient ways to use this language.

Product Description:
Perl is a versatile, powerful programming language used in a variety of disciplines, ranging from system administration to web programming to database manipulation. One slogan of Perl is that it makes easy things easy and hard things possible. Intermediate Perl is about making the leap from the easy things to the hard ones.
Originally released in 2003 as Learning Perl Objects, References, and Modules and revised and updated for Perl 5.8, this book offers a gentle but thorough introduction to intermediate programming in Perl. Written by the authors of the best-selling Learning Perl, it picks up where that book left off. Topics include:
Packages and namespaces
References and scoping
Manipulating complex data structures
Object-oriented programming
Writing and using modules
Testing Perl code
Contributing to CPAN
Following the successful format of Learning Perl, we designed each chapter in the book to be small enough to be read in just an hour or two, ending with a series of exercises to help you practice what you've learned. To use the book, you just need to be familiar with the material in Learning Perl and have ambition to go further.
Perl is a different language to different people. It is a quick scripting tool for some, and a fully-featured object-oriented language for others. It is used for everything from performing quick global replacements on text files, to crunching huge, complex sets of scientific data that take weeks to process. Perl is what you make of it. But regardless of what you use Perl for, this book helps you do it more effectively, efficiently, and elegantly.
Intermediate Perl is about learning to use Perl as a programming language, and not just a scripting language. This is the book that turns the Perl dabbler into the Perl programmer.
Immensely popular Perl combines the best features of C, key UNIX utilities, and powerful regular expressions. Perl is commonly used for web programming, as well as e-mail and Usenet news filtering. Fast becoming the system administrator’s scripting language of choice, Perl is also useful for file and directory manipulation, database access, and a broad range of daily system operator chores.
This second edition dispels the image of Perl as a sometimes confusing, obscure language, and instead, promotes Perl as a legible, sensible programming language. Concise and focused, this book reaches out to users of all experience levels, and covers basic to advanced aspects of Perl, Apache modPerl, and Perlscript (for use with Wintel systems). This book also stresses the cross-platform nature of Perl.
If you have a Perl programming question, you'll find the answer quickly in this handy, easy-to-use quick reference. The Perl Pocket Reference condenses and organizes stacks of documentation down to the most essential facts, so you can find what you need in a heartbeat.
Updated for Perl 5.14, the 5th edition provides a summary of Perl syntax rules and a complete list of operators, built-in functions, and other features. It's the perfect companion to O'Reilly's authoritative and in-depth Perl programming books, including Learning Perl, Programming Perl, and the Perl Cookbook..
