- GNU is an operating system and an extensive collection of computer software. GNU is composed wholly of free software, most of which is licensed under the GNU Project's own General Public License (GPL). GNU is a recursive acronym for "GNU's Not Unix!".
Because the GNU kernel, Hurd, is not production-ready , GNU is usually used with the Linux kernel. Arch Linux is such a GNU/Linux distribution, using GNU software like the Bash shell, the GNU coreutils, the GNU toolchain and numerous other utilities and libraries. This page does not attempt to list all of the nearly 400 GNU packages and only highlights some.
GNU software is documented using the Texinfo typesetting syntax. You can view Info documents using the
info program, provided by the package.
While most GNU software also provides man pages, the Info documents tend to be more comprehensive.
- GRUB — GRUB is the bootloader from the GNU project.
- Bash — It is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh).
