Beginning Perl, Second Edition is a well-named text that starts exactly where it claims…This book is a fine place to start.

— James Edward Gray II, Slashdot contributor

...there are great examples, and projects assigned after each chapter to help you really understand and remember how to code in Perl.

— Mark Spritzler, JavaRanch Bartender

This book is a well-conceived introduction to Perl in tutorial form... A Very Good Book. :) :) :) :) of 5.

— George Woolley of Oakland Perl Mongers

The Perl (this book) teaches is strong industry-standard Perl that is…considered best practice.

— Jack Herrington, Editor, Code Generation Network

Originally created as a powerful text processing tool, Perl has since evolved into a multi-purpose, multi-platform language capable of implementing a variety of tasks such as system administration, CGI and network programming, XML processing, and more. Beginning Perl, Second Edition provides valuable insight into Perls role regarding all of these tasks and more.

Commencing with a comprehensive overview of language basics, you'll learn all about important concepts such as Perl's data types and control flow constructs. This material sets the stage for a discussion of more complex topics, such as writing custom functions, using regular expressions, and file input and output. Next, we move on to the advanced topics of object oriented programming, modules, CGI programming, and database administration with Perls powerful database interface module, DBI. The examples and code provided offer you all of the information you need to start writing your own powerful scripts to solve the problems listed above, and many more.

Whether you are a complete novice or an experienced programmer, Beginning Perl, Second Edition offers an ideal guide to learning Perl.

5.0 out of 5 stars Great for Teaching Perl Feb. 14 2007
By F. L. Fabrizio - Published on Amazon.com
Format:Paperback
I use this book to teach Perl in a university course. I feel it does a very good job at exposing just enough of Perl to make it useful without confusing beginning students. I chose this over O'Reilly's Learning Perl (also a good book) because this book goes into References, Modules and a bit of OO Perl, and also has what I feel is slightly better treatment of shortcuts like $_ as well as lexically-scoped variables with 'my'. O'Reilly has broken these topics across two books (Learning Perl and Intermediate Perl), both fine books but I only want the students to have to buy one book. I feel that Perl is not very useful without references, so that was the major reason for switching to this book for a beginning Perl course. I highly recommend it.

5.0 out of 5 stars Beginning Perl, 2nd Edition Oct. 6 2004
By T. Barr - Published on Amazon.com
Format:Paperback
Beginning Perl, 2nd edition, by James Lee, et al., is a splendid

introduction to the Perl programming language, version 5.8.3. The flow

of the book is logical, straightforward, and highly readable. Text is

heavily sprinkled with program examples that the reader can easily try

out along the way, as well as exercises at the end of most chapters,

with solutions in the appendix. Chapters are short, clear, and

engaging.

After a brief discussion of the history of Perl and a listing of

numerous helpful online resources, the book quickly moves on to the

logistics of running a Perl program, followed by descriptions of basic

program elements and control flow. Then it's ahead to more

sophisticated data elements - lists, arrays, and hashes - and finally

functions and subroutines.

After a solid and seemingly effortless explanation of these "basics,"

the book moves to one of the most powerful features in Perl - regular

expressions - and how these can be used to access files and data. From

there, the discussion expands to string processing and references. The

book concludes with discussions of more "advanced" Perl features,

including object-orientation, modules, and use with webservers and

databases.

Regardless of topic, the writing style stays crisp, clear, and

example-filled, making this book a highly effective and enjoyable way to

get a jump-start into Perl programming for the novice or a quick

refresher for the expert wanting a Perl 5 update.

5.0 out of 5 stars Perl from basics to objects Oct. 12 2004
By Jack D. Herrington - Published on Amazon.com
Format:Paperback
This is a very capable introduction to Perl that I think is intended for reasonably experienced programmers. It is not intended to teach Perl as a first computer language, and it does not pander to the reader. The Perl it teaches is strong industry standard Perl that is in line with what could reasonably be considered best practice. That's something in a language that prides itself on having many ways to do one thing.

The book covers the entire topic of Perl from the basics of writing a script, through functions, modules, and into object oriented programming. It also covers vital community information such as the use of CPAN.

If you have not read Programming Perl then I believe you should start there. But if you find that book has too much of a learning curve then I would recommend this book or Learning Perl (O'Reilly.)

4.0 out of 5 stars Very suitable for newcomers Sept. 9 2004
By W Boudville - Published on Amazon.com
Format:Paperback
For server side scripting, Perl is now one of the favourite languages. Lee shows how you can quickly and easily grasp the basic syntax and begin programming usefully in it. He stresses in his presentation that no prior knowledge of Perl is needed. Strictly, not even of another programming language. If this describes you, his book should be quite understandable, given just a modicum of maths background.

But having said that, if you've written in any other programming language, then you'll breeze through a lot of the texr. It's just a question of picking up Perl's syntax.

Where things might get slightly hairy are when references are discussed. Like in C or C++, some beginners find this awkward. It's been mentioned by others that in general, in computing, one of the dividing lines in understanding is the topic of references (and pointers). It doesn't seem to be a strong function of how well an author explains it, but more of the student's intrinsic aptitude for the field.

Hopefully, you will find Lee's explanations lucid.

4.0 out of 5 stars Excellent book for beginners. Don't look any further Oct. 22 2005
By R. Blanche - Published on Amazon.com
Format:Paperback
I have several years experience in programming, but I didn't know anything about Perl. I bought this book because of the good reference I read in Amazon, and they weren't wrong. The authors do a great job describing with a very simple and direct language all topics. The book is full of examples, and practically after each paragraph there is some code you can try in your computer. All the code in the book works fine, there are no errors and if you don't want to type it, you can download it from the Apress web site. The explanation of every piece of code is clear, simple and enjoyable, you can't get lost.

I give 4 starts to the book because the chapter where describes how to download the DBI, CGI and other modules, it didn't work for me, and this is the only part of the book I found a little confuse. In order to download all the modules you need, simply follow this rules:

- Type "ppm" in the command line

- Type "install DBI"

- Type "install CGI"

- Type "install DBD-mysql"

- And finally type "quit"

As well you can downloads from the "apachefriend" website the complete installation of Perl, MySql, etc. All these process is very straightforward and you are ready to go.

The second reason why I didn't give 5 stars is because I was expecting an appendix with the references for the most common methods of the CGI module to create HTML tags, but it doesn't have anything, just what is in the chapter and that is not enough.

This is definitely a book for beginners (just like me) and I strongly recommend it. I enjoyed my experience studying with this book, and now I want go further with a more advanced book. I wish the authors could write a second episode of Perl.
