Programming is about solving problems and good communication. But before code is written, you need to know how to solve the problem. Breaking the problem into component parts assists in the process. And being able to model the problem so that it’s easy to implement and test also helps. Combine this with a solid understanding of the programming language itself – a good programming book contributes to all aspects of problem solving. Perl has the virtue it can solve a problems in a few lines of code. Perl programmers solve problems and get things done.
The popularity of a book is influenced by personal feelings, tastes, and opinions. Programming books accord to this general rule. There is a wide range of Perl books. As Perl is an open source programming language, with an eclectic heritage written by Larry Wall with thousands of contributors, it is welcome some authors have released their Perl books under a freely distributable license. I select 16 excellent Perl books (divided into 2 pages) which help master this language. All of the books are released under an open source license.
By way of background, Perl is a high-level, general-purpose, interpreted, scripting, dynamic programming language released under the GPL or Artistic license. Perl’s syntax has its roots in shell scripting tools, borrowing features from other languages including C, shell script (sh), AWK, and sed. It is available for most operating systems. Perl is implemented as an interpreted (not compiled) language. It is procedural, with variables, expressions, assignment statements, control structures, blocks and subroutines.
Perl is a versatile language. It is often used to write (CGI) scripts, manipulate text, general web programming, networking, system administration, prototyping, database access, and graphical programming. One of the most powerful features of Perl is its extensive library of modules. Many of these modules are available from the Comprehensive Perl Archive Network, which mirrors over 178,000 Perl modules.
