Yep. The tools you need are known as "Bash" and "grep". :-)

Find information about the former here, and download it thus. Grep you may download with this link. Most of the other GNU command line tools are available too, if you poke around.

With sufficient work, Windows can be made much more tolerable for Unix folks. Kind of amusing, too. Hard to tell which people think is weirder... your running something they've never seen before, or your sitting there with four DOS windows open, and the mouse laying forgotten somewhere.
