A Regex Introduction

This is an easy to understand, straight-forward explanation or Regex (Regular Expressions), how they're used and includes examples.

What is regex?

A regular expression (or regex) is a simple, rather mindless way of matching a series of symbols to a pattern you have in mind. Mostly, if you want to find a pattern in text, regex is the way to go, and Perl regex will get you there. As the Perl manual says:

"Perl is an interpreted language optimized for scanning
arbitrary text files, extracting information from those
text files, and printing reports based on that information"

Regex has been around for some time - those who have struggled with computer theory (in basic computing courses at university) will know it well. Actually, it's not that bad. The basic ideas are simple, but powerful.
