The GNU Core Utilities or coreutils is a package of GNU software containing implementations for many of the basic tools, such as cat, ls, and rm, which are used on Unix-like operating systems.

In September 2002, the GNU coreutils were created by merging the earlier packages textutils, shellutils, and fileutils, along with some other miscellaneous utilities.[3] In July 2007, the license of the GNU coreutils was updated from GPL-2.0-or-later to GPL-3.0-or-later.[4]

The GNU core utilities support long options as parameters to the commands, as well as the relaxed convention allowing options even after the regular arguments (unless the POSIXLY_CORRECT environment variable is set). Note that this environment variable enables a different functionality in BSD.

See the List of GNU Core Utilities commands for a brief description of included commands.

Alternative implementation packages are available in the FOSS ecosystem, with a slightly different scope and focus, or license. For example, BusyBox which is licensed under GPL-2.0-only, and Toybox which is licensed under 0BSD.
