Welcome

Hi! I'm Bill Weinman, and I'd like to welcome you to Perl 5 Essential Training. Perl is a very flexible and powerful programming language that's well suited for a variety of projects, from simple scripts to complex web applications. In this course, I'll show you how to use Perl and how to take advantage of its unique and powerful features. I'll start by giving you an overview of Perl, so you can get started right away. This Perl Quick Start is designed for the experienced programmer who wants to leverage their existing knowledge to get up to speed with Perl quickly and with as little detail as necessary.

Then we'll get right into the details of the language, syntax and structure, conditionals, loops, operators, data structures, subroutines, and regular expressions. I'll show you how to do common tasks in Perl including File I/O, databases, CGI and web development. And I'll show you how to use modules to leverage your work and the work of others to get your projects done faster, and with less effort. Finally, I'll walk you through some real-world examples of working Perl code, so you can see how the pieces fit together, and to help you get started on your own projects.

This course is intended for users who already have some programming knowledge. If you have experience in at least one other modern programming language, this course is for you. I've been a programmer since the 70s, and I've been using Perl since the early 90s. I'm glad to be able to share the knowledge and experience I've gained along the way, so that you can write better applications today. Now let's get started with Perl 5 Essential Training.

Q: In the Chapter 9 movie "Matching classes of characters," the author states that \w and \W are used to match both any word character and whitespace. Is the same code used for both word matching and whitespace matching?
A: No. While \w and \W are used to match any word in a string, the correct code for whitespace matching is \s or \S.
