Questions tagged [gnu]

GNU is a Unix-like operating system that is free software and developed by the GNU project. GNU is normally used with the Linux kernel. This tag can be used for questions relating to GNU software, particularly programs that differ from the POSIX standard or their BSD equivalents.

GNU stands for GNU's Not Unix.

The original kernel intended for GNU, Hurd, has been under development since 1984, and has yet to release a stable version. For this reason, most GNU operating systems use as their kernel.

The GNU tag can be used for any software developed by the GNU project.
