Cygwin

[old.Garmoan]

not really an os but would be very useful for people out there with one computer and would like to work with Unix on thier windows pc.

www.cygwin.com

its a nifty program that doesnt take a lot of space that installs Unix API's onto your pc, thne your able to work with Unix in a MS-Dos prompt window.. very easy to use and quite useful (but it may slow down your pc by a bit but thats for me, damn 128 RAM)

That's how I run an eggdrop bot under Win98

Built in for me though, don't have to put in any effort.

Cygwin can be handy at times, but it makes my PC speaker bleep
