GNU is an operating system that is free software—that is, it respects users' freedom. The GNU operating system consists of GNU packages (programs specifically released by the GNU Project) as well as free software released by third parties. The development of GNU made it possible to use a computer without software that would trample your freedom.

The free software movement campaigns to win for the users of computing the freedom that comes from free software. Free software puts its users in control of their own computing. Nonfree software puts its users under the power of the software's developer. See the video explanation.



自由ソフトウェアは自由の問題であり、値段の問題ではありません。この考え方を理解するには、「ビール飲み放題(free beer)」ではなく、「言論の自由(free speech)」を考えてください。


  • どんな目的に対しても、プログラムを望むままに実行する自由 (第零の自由)。
  • The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.
  • The freedom to redistribute copies so you can help others (freedom 2).
  • The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.





“GNU”という名称は、“GNU's Not Unix”(GNUはUnixではない)の再帰頭字語です。“GNU”はグヌー[ˈgnuː]と発音します。一音節で、“grew”のrnで置き換えて言うようにです。


GNU自身のカーネル、The Hurdは1990年に(Linuxが開始される前に)開始されました。興味深い技術的プロジェクトですので、ボランティアによってHurdの開発は続きます。

RCSはオリジナルの版管理システム(Revision Control System)です。ファイル毎で扱われ、CVS, Subversion, Gitなどの新しいバージョン管理システムと対照的です。これは、たとえば、本質的に一つのマシンにローカルなことが多い、システム管理のファイル、などに有用です。(ドキュメント)
