ack is the new grep

This is a great improvement on your toolkit(if you use grep, that is).

Checkout ack, auto-entitled better than grep.

There's also a very nice Textmate plugin to replace the Find in Project. Its so much faster, does not block your textmate when searching and you are able to copy-paste the end results.

ps: I found it, from the tools on the edge article. Go have a peek you might find some more gems for your toolbox.
