The GNU/Linux naming controversy is a dispute among members of the free and open source software community over how to refer to the computer operating system commonly called Linux.
GNU/Linux is a term promoted by the Free Software Foundation (FSF), its founder Richard Stallman, and its supporters, for operating systems that include GNU software and the Linux kernel. The FSF argues for the term GNU/Linux because GNU was a longstanding project to develop a free operating system, of which they say the kernel was the last missing piece.
Proponents of the Linux term dispute GNU/Linux for a number of reasons, such as the fact that the term Linux is far more commonly used by the public and media. Below some GNU/Linux examples.
