In the days before personal computers, BASIC was the easy programming language to learn, and serious programmers learned FORTRAN or COBOL to do real work. Many people have discovered that Perl is both a great beginning programming language and one that enables them to write powerful programs with little effort.

The multifaceted Perl programming language is captured in a new profile in this fascinating, graphically driven synopsis by a group of graphical text designers at Maran Graphics. Perl newbies of marginal literacy--or who have no patience for textual explanations of programming tasks--will find the visual blueprint to be a stimulating and highly parallel interface for the communication of Perl syntax, code structure, and functionality.But there is a fine line between simple and simplistic. In an effort to convey the live look-and-feel code development environment, the Maran designers depict the "pico" editor window around every code snippet, and pico's own interface becomes synonymous with Perl by the third example. Moreover, the editors underestimate newbie user interface experience when they remind the user to "position the cursor" in certain locations before typing the next segment of the demonstration code, even after 16 chapters. Code annotation is graphically stimulating but conceptually mundane throughout.
The Maran group succeeds in hitting Perl's most important high points in its 285-page jaunt across the language. Examples for variable dereferencing, making and using Perl modules, building dynamic Web interaces, accessing databases, and designing for the CGI server-side Web interface are all included. The accompanying CD-ROM contains Perl 5.6 distribution for Unix, ActivePe

Learning Perl, popularly known as "the Llama," is the book most programmers rely on to get started with Perl. The bestselling Perl tutorial since it was first published in 1993, this new fifth edition covers recent changes to the language up to Perl 5.10.
This book reflects the combined experience of its authors, who have taught Perl at Stonehenge Consulting since 1991. Years of classroom testing and experience helped shape the book's pace and scope, and this edition is packed with exercises that let you practice the concepts while you follow the text. Topics include:- Perl data & variable types
- Subroutines
- File operations
- Regular expressions
- String manipulation
- Lists & sorting
- Process management
- Smart matching
- Using third party modules
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.

In the days before personal computers, BASIC was the easy programming language to learn, and serious programmers learned FORTRAN or COBOL to do “real work.” Today, many people have discovered that Perl is both a great beginning programming language and one that enables them to write powerful programs with little effort.If you’re interested in discovering how to program (or how others program), Perl For Dummies, 4th Edition, is for you. If you already know something about programming (but not about Perl), this book is also for you. If you’re already an expert programmer, you’re still welcome to read this book; you can just skip the basic stuff (you never know what kind of new tips and tricks you’ll pick up).
This reference guide shows you how to use Perl under many different operating systems, such as UNIX, many flavors of Windows (Windows 95/98, Windows NT, Windows 2000, Windows Me, and Windows XP), and Macintosh OS 9 and OS X; in fact, Perl runs on many more operating systems than these.
Here's a sampling of what Perl For Dummies, 4th Edition, has to offer:
- Installing Perl on various platforms
- Nailing down the basics of building Perl programs
- Working with text and numbers
- Constructing lists and working with them
- Creating conditionals and loops
- Delving into more advanced features such as operators and functions
- Reading and writing files and directories
- Using subroutines for modularity
- Demystifying Web server programs
- Creating your own Internet clients
The Perl programming language enables you to write fully working computer programs with just a few steps. It’s particularly good at common programming tasks, such as reading and writing text files, but it also excels at reducing the work that programmers have to do. Perl For Dummies, 4th Edition, shows you how to do all of that and how to modify programs to your heart’s content. After all, one of the common phrases in the world of Perl programmers is, “There's more than one way to do it.”

When it comes to working a little "behind the scenes" magic for a Web site or putting together a UNIX script which interrogate databases and produce reports based on the information they contain, there are few better languages to do the job than Perl.Learning Perl draws on the expertise of two of the major supporters of this highly flexible language, Randal Schwatrz and Tom Christiansen, to produce an introductory manual which manages to be concise yet informative throughout.
Weighing in at a mere (for a computer manual) 271 pages it achieves admirably what it sets out to do--teach Perl basics and no more. From the introduction to the different variable types through hash arrays, file access, process management and coding for the World Wide Web, it's a well-paced easy-to-understand book which assumes a rudimentary knowledge of programming but no more.
With its multitude of clear examples which help to hammer home the many points made and set exercises at the end of each chapter, it builds knowledge rather than drowning the reader with information as many other books seem to do.
This is the first in a series of books on the subject from O'Reilly Publishing, the others being Programming Perl, Advanced Perl Programming and the Perl Cookbook and it truly is a great introduction to a language which is enthusiastically supported by develo

If you ask Perl programmers today what book they relied on most when they were learning Perl, you'll find that an overwhelming majority will name Learning Perl--also known affectionately as "the Llama." The first edition of Learning Perl appeared in 1993 and has been a bestseller ever since. Written by two of the most prominent and active members of the Perl community, this book is the quintessential tutorial for the Perl programming language.
Perl began as a tool for Unix system administrators, used for countless small tasks throughout the workday. It has since blossomed into a full-featured programming language on practically every computing platform, and is used for web programming, database manipulation, XML processing, and (of course) system administration--all this while still remaining the perfect tool for the small daily tasks it was designed for. Perl is quick, fun, and eminently useful. Many people start using Perl because they need it, but they continue to use Perl because they love it.
The third edition of Learning Perl has not only been updated for Perl 5.6, but has also been rewritten from the ground up to reflect the needs of programmers learning Perl today. Informed by their years of success at teaching Perl as consultants, the authors have re-engineered the book to better match the pace and scope appropriate for readers trying to
If you're just getting started with Perl, this is the book you want—whether you're a programmer, system administrator, or web hacker. Nicknamed "the Llama" by two generations of users, this bestseller closely follows the popular introductory Perl course taught by the authors since 1991. This 6th edition covers recent changes to the language up to version 5.14.
Perl is suitable for almost any task on almost any platform, from short fixes to complete web applications. Learning Perl teaches you the basics and shows you how to write programs up to 128 lines long—roughly the size of 90% of the Perl programs in use today. Each chapter includes exercises to help you practice what you've just learned. Other books may teach you to program in Perl, but this book will turn you into a Perl programmer.
Topics include:
- Perl data and variable types
- Subroutines
- File operations
- Regular expressions
- String manipulation (including Unicode)
- Lists and sorting
- Process management
- Smart matching
- Use of third party modules
