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 Perl's role in 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 Perl's 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.
This was my first Perl book. After a few chapters and some googling I was able to write a few "real world" scripts/programs, so it does its job. My only real criticism is that it does too much hand holding; I'm not new to programming, so I found the explanations for basic programming concepts to be distracting. It's trying to be a book both for people new to programming and people who are experienced programmers but new to Perl. I think it would have been better just choose one of those.
It's a good book though, you'll come away with enough Perl to get stuff done. It just won't be your only Perl book, it's called Beginning Perl for a reason; there's a lot it doesn't cover.
