Perhaps no innovation of the Unix environment has been more influential than regular expressions. Regular expressions really do give you a world of opportunities, if you know what you are doing. You can use regular expressions to define filters and simplify searches.

The program supports interactive testing based on a variety of tools, and it can give you ready-to-use regular expressions.
