I have blogged before that knowledge of command-line tools is essential to take the next step in programming productivity. I think it would be useful to provide simple tutorials for these powerful tools, starting with find. I hope you agree, and would appreciate your feedback via the contact page or in the comments.

Global Regular Expression Print is a staple of every command-line user’s toolbox. As with find, it derives a lot of power from being combined with other tools and can increase your productivity significantly.
