Learning Perl. UNIX Programming (Nutshell Handbook) [Englisch] [Taschenbuch]

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 developers and Web coders worldwide. Well worth a read.

In this update of a bestseller, two leading Perl trainers teach you to use the most universal scripting language in the age of the World Wide Web. With a foreword by Larry Wall, the creator of Perl, this smooth, carefully paced book is the "official" guide for both formal (classroom) and informal learning. It is now current for Perl version 5.004. Learning Perl is a hands-on tutorial designed to get you writing useful Perl scripts as quickly as possible. Exercises (with complete solutions) accompany each chapter. A lengthy, new chapter in this edition introduces you to CGI programming, while touching also on the use of library modules, references, and Perl's object-oriented constructs. Perl is a language for easily manipulating text, files, and processes. It comes standard on most UNIX platforms and is available free of charge on all other important operating systems. Perl technical support is informally available -- often within minutes -- from a pool of experts who monitor a USENET newsgroup (comp.lang.perl.misc) with tens of thousands of readers. Contents include: A quick tutorial stroll through Perl basics Systematic, topic-by-topic coverage of Perl's broad capabilities Lots of brief code examples Programming exercises for each topic, with fully worked-out answers How to execute system commands from your Perl program How to manage DBM databases using Perl An introduction to CGI programming for the Web

Randal L. Schwartz is an eclectic tradesman and entrepreneur, making his living through software design, technical writing and training, system administration, security consultation, and video production. He is known internationally for his prolific, humorous, and occasionally incorrect spatterings on Usenet--especially his "Just another Perl hacker" signoffs in comp.lang.perl. Randal honed his many crafts through seven years of employment at Tektronix, ServioLogic, and Sequent. Since 1985, he has owned and operated Stonehenge Consulting Services in his home town of Portland, Oregon. Tom Christiansen is a freelance consultant specializing in Perl training and writing. After working for several years for TSR Hobbies (of Dungeons and Dragons fame), he set off for college where he spent a year in Spain and five in America, dabbling in music, linguistics, programming, and some half-dozen different spoken languages. Tom finally escaped UW-Madison with B.A.s in Spanish and computer science and an M.S. in computer science. He then spent five years at Convex as a jack-of-all-trades working on everything from system administration to utility and kernel development, with customer support and training thrown in for good measure. Tom also served two terms on the USENIX Association Board of directors. With over fifteen years' experience in UNIX system administration and programming, Tom presents seminars internationally. Living in the foothills above Boulder, Colorado, surrounded by mule deer, skunks, and the occasional mountain lion and black bear, Tom takes summers off for hiking, hacking, birding, music making, and gaming.
