Book overview

Perl is a well-established programming language that has been developed through the time and effort of countless free software programmers into an immensely powerful tool that can be used on pratically every operating system in the world. Perl started out as the "Swiss army knife" of computer languages and was used primarily by system administrators, but over time it's grown into an immensely robust language used by web-developers and programmers worldwide. It's also a great way to learn programming techniques and develop your own style of coding.

"There's more than one way to do it" is the motto of Perl, but this book aims to take you through them all. We'll take you from installation, through the core language elements - regular expressions, references, modules and the like - and onto basic applied techniques. You'll see how to access and work with databases in Perl, write CGI scripts to generate web pages and beyond. Coverage is bang up to date, using Perl 5.6 in all our examples and there's a handy reference section in the back.

Who is this book for?

This book is for those new to programming who want to learn with Perl. You will find it easier if you already have some basic programming experience, but the material covered can be mastered by anyone with just a text editor, some common sense and a computer. If you want to learn how to program with Perl and then find out how far you can go with it, this is the book for you. An excellent companion on any programming course.
