GNU (body, project) /g*noo/ 1. A recursive acronym: "GNU's Not Unix!". The Free Software Foundation's project to provide a freely distributable replacement for Unix. The GNU Manifesto was published in the March 1985 issue of Dr. Dobb's Journal but the GNU project started a year and a half earlier when Richard Stallman was trying to get funding to work on his freely distributable editor, Emacs.
Emacs and the GNU C compiler, gcc, two tools designed for this project, have become very popular. GNU software is available from many GNU archive sites. See also Hurd. 2. (person) John Gilmore. [Jargon File] Last updated: 1997-04-12
