The all-time best book on Perl I've read...

Read this to review Perl, since it's been 10 years since I'd written any. Don't skip the footnotes, especially if you are an old school UNIX/C programmer, lots of in-jokes to be found there. Great introduction to the language too, at least for those coming from a C or C background.

Gentle and entertaining introduction to basic Perl programming. It's probably not the most efficient way to learn the language for an experienced programmer since it gets a bit chatty and drawn out at times and does not get into advanced features. Nonetheless, it was worth the time to read.½

It's the llama book. You know what it is. It's hard to force myself to learn Perl because I can just get things done in Bash.

Technical manual. Useful starter for the Perl progamming language.

Totally worth the price and the time it takes to learn. I know I will go back to this over and over if I'm trying to write any Perl scripts.

Glimrende introduktion til Perl programmeringssproget. Der er små jokes rundt omkring, men også nyttige småprogrammer.
Desværre var det her en paperback udgave og den går i stykker i ryggen, når der har været brugt et stykke tid.

Azt még csak-csak el tudtam fogadni, hogy a fordítás tele van nehezen érthető és magyartalan mondatokkal. Bosszantó, de szakkönyvnél nem ez a lényeg. Ami valójában használhatatlanná teszi a könyvet, az a példaprogramokban elrejtett hibák nagy száma. Hiányzó zárójelek, operátorok garantálják, hogy a példaprogramok nagy része használhatatlan legyen. Tipikusan a perl egy olyan nyelv ahol erre nagyon kellene figyelni.

A könyvet csak azért nem osztályozom, mert nem lehet külön értékelni az eredeti könyvet (amennyire meg lehet ítélni a magyar kiadás alapján, ez egy elég jó bevezető könyv a perl nyelvhez) illetve a magyar kiadást (ami viszont pocsék).

My edition is a little old now, but this is absolutely the best book on Perl if you want to learn this powerful, complex language. Just be sure to get the newest edition available.

The original "Llama" book from O'Reilly, this was an outstanding introduction to the mysteries of this powerful programming language. Twinned with Larry Wall's "Camel" book, the pair took many of us from stunned neophytes to halfway competent authors of code that worked.

Perl is an open source CGI scripting and web programming language. Perl is one of the most popular web programming languages because of its powerful text-manipulation capabilities. A huge number of Perl scripts are freely available on the web for download.

This textbook was written to be a gentle introduction to Perl. It is not a comprehensive guide to Perl. It is a companion volume to Programming Perl, Second Edition by Larry Wall, Randal L. Schwartz, and Tom Christiansen.

Advanced topics at the end of the book cover CGI programming, library modules, references, and object-oriented programming.

Perl will run on practically any computer platform including MS-DOS, VMS, OS/2, Macintosh, all flavors of Windows, UNIX, and Linux,

The exercises in the book can be downloaded from http://www.oreilly.com or by FTP.

You can visit the Perl home page at http://www.perl.com/perl/.

Absolutely essential for the Perl programmer. I learned Perl using this book and still refer to it from time to time.

I would say that this is THE BOOK for learning Perl. Funny and easy to read.

A standard reference.

A classic. I own two copies, at work and at home. Sometimes I pick a page at random, I'm sure it will make me laugh in a page or two.½

This book was required for class for Library School. Compared to other Perl books I looked at through the semester, this book is long, confusing and drawn out. Some areas could and have been explained much better in other books. This is only recommended for people who understand programming already and not for beginners.

The "Camel Book", as this book is often called, is the Perl Bible. It's not only an exhaustive reference, but clearly written any *funny* to boot. The humour pervades the text, making a sometimes dry subject much more approachable.

No Perl programmer can afford to be without this book, and anybody considering writing a technical reference should refer to this book to see how it's done.

Absolutely indispensible. I've tried other Perl books when I couldn't get my hands on mine and none even compare. Obviously later editions are even better.
