I would like to start learning some basic *nix commands but I really don't feel like partitioning my harddrive and installing a *nix OS right now.

I've been looking around for a *nix command processor that I can run on Win 7 OS. Im not even sure if they, or even one, exists.

Really Im just looking for a DLable software prog. or online site where I can practice *nix commands in real time and with real effects on my Win 7 OS.

Anyone point me in the right direction, or at least let me know if Im wasting my time in this search.

thanks again
