Ever wish you had more Unix in your life?
Sick of shutting down Windows and booting into Linux to get a decent command line?
Tired of Command.com not recoginzing perfectly good commands like "ls" or "cat"?
Try Cygwin (from the kind folks at RedHat):
Cygwin It gives you a Bash command line in Windows and a ton of GNU tools like GCC and Apache, you can even run XWindows.
