I've been a Unix user for seven+ years, and have some programming experience, although I am by no means really knowledgable about either. When I entered my most recent job, I needed to learn Perl fast, and so I used this book to help me get started.
From a self-teaching perspective, I found this book to be exactly what I needed. I'll admit that the first chapter (a general description of the Perl language) was not very helpful, but I found the division of the rest of the book by small pieces of the syntax (scalars, arrays, hashes, regular functions, i/o, etc.) to suit my needs, which tended to be along the lines of: I need to do x right now. I learned the easy stuff really quickly, and I still use the book as a constant reference.
Now, it is just a beginner's text, so it is not an ideal complete reference, and you won't learn anything particularly nifty. However, if you need to both learn how to program and actually do some programming at the same time (i.e. not in a class-room setting), Learning Perl can be a wonderful text.

Excellent.
I came to this book knowing next to nothing about Perl, and with a few misconceptions to boot (that Perl's syntax is 'write-only', it's primarily a CGI tool, etc.), and now I am not sure that epiphany would cover it. In 12 years of learning and using programming languages, I don't think I have come across anything so enchanting.
One of the best parts of the book: the authors. Add Schwartz & Christiansen to Elliotte Rusty Harold, Petzold, and a very few others who are truly effective technical writers. Classic O'Reilly easygoing style, never condescending, and eerily consistent in presenting just the right amount of information on the given topic.
Every programmer (even non-Perl ones) should read 'Programming Perl' by Larry Wall. But to learn Perl, and take the first step down a long and magical road, buy this book.
I had a few nits, but by the time I finished the book, I had forgotten most of them. As close to 5 stars as I will ever give for a technical book.

This accessible and practical book can make a Non-Programmer into a Proud CGI Guru, given that the beginner understands some basic logical structures, and is willing to meet the authors halfway.
PROBLEM 1: The book assumes a fairly extensive Unix background, so doesn't always explain itself where that's concerned. SOLUTION: Just ignore the bits that don't apply to you and keep going.
PROBLEM 2: The first chapter can be intimidating. SOLUTION: Understand it to be an overview: "Here's what you can do with perl." Run its programs to see how they work, experiment with them, but don't freak out if you don't understand them completely. Alternately, just skip on to Chapter 2.
We enjoyed Learning Perl, and found it a good beginner's book for this language or for programming in general. The touches of humor could be annoying to some, but we thought they added readability and interest.

A very, very good book for beginners. Extremely helpful, detailed explanations of what's going on and more. It says UNIX on the cover but I am using a Windows NT platform and almost everything works as is. If you want to learn Perl, start here.

This is not a bad book, but I'm still surprised by the generosity of the reader reviews. Perl is something of a cult, so I think in a lot of cases a positive review means "I like Perl" more than it means "I like 'Learning Perl.'" People hesitate (understandably, I think) to insult a book that's closely associated with a great open-source language.
I myself think Perl is great, but I have some serious problems with the way this book was written and edited. The authors can't seem to decide whether this should be an easy book for programmers, a difficult book for non-programmers, or even (at times) an easy book for non-programmers. That is to say, the tone, style, and assumptions about the audience change throughout, sometimes from page to page. Key concepts are glossed over with a minimum of explanation (the chapter on hashes, particularly, is a disgrace); then, defying all reason, very simple concepts are overexplained for two or three pages. The authors have been too close to their subject for too long, and they seem to have forgotten what they learned and the order in which they learned it. Maybe a newbie co-author might have helped.
If you are an experienced developer or are comfortable with UNIX, you'll get a lot of benefit from "llama." Otherwise, though, start with another book, or learn something about UNIX first. Then return to this book, and you should have an easier time of it.

Von Ein Kunde am 27. April 2000
Format: Taschenbuch
I picked up Learning Perl with very little programming experience (only having completed a compulsory Visual Basic course in high school), and found it easy to read and understand.
The first chapter, A stroll Through Perl, is perhaps the biggest flaw in the book. Rather than introducing the capabilities of Perl (which I think is what the author's intended), it bogs the new reader down in detail and seems to set forth an avalanche of cryptic code at you. It was so bad that, thinking that Chapter 1 was an indication of the rest of the book (ie it was all too cryptic and meant for seasoned programmers), I set the book aside for a few months.
I came back to the book when a friend of mine picked it up, and, after skimming over Chapter 1, was pleasantly suprised. The rest of the book is easy to read and understand, though at times a little dense for the new programmer, and immediately useful. The examples are good illustrations of implementation ideas for concepts described in a chapter, and the excercises at the end of each chapter are good indications of what you've learnt. The book introduces new concepts smoothly and quickly integrates them into existing material, and culminates in an especially interesting and useful chapter on CGI (which is really what I wanted to use Perl for).
Overall, it's a great book, even for people who are new to programming: with a little dedication you'll be able to blaze through the chapters and become proficient at Perl basics. Some organisational errors let it down and make the introductory pages unjustifiably daunting for those new to programming, but other than that, it was a very satisfying and self-contained tutorial for Perl users.
