cygwin

so I installed cygwin on my pc at work cause I need to run bash scripts and shit that a fired colleague left for me to deal with. Is there anything cool I can do with cygwin besides going crazy on grep, cut, tail and shit? I've been playing typespeed for two hours today, but I mean, like, really cool?

Also it seems I cant mount any folders that are beneath my home directory, I mean wtf? Cygwin moans that the device is busy or something, but its not fucking busy, it isnt doing shit. Is there a way to change the home dir itself?

you can get X and Wine, run them under Cygwin under Windows, and then emulate yourself running your own Windows programs.  FUN!
