What is GNU?  GNU's Not Unix.  Ok we know what it is not, but what is it?  It is a free-source/software implemention of a Unix-like OS and Unix utilities.  It is also a license to release software.  For more details check out GNU's homepage at  Some of GNU's more well known works are GNU/Linux, the gcc compiler, emacs editor, plus many others... One cannot mention GNU without mentioning the Free Software Foundation (FSF) and the founder ex-MIT hacker/coder extraordinare Richard Stallman. (Not to mention obsessive control freak).
