The GNU Core Utilities or coreutils is a package of GNU software containing reimplementations 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.^[2] In July 2007, the license of the GNU coreutils was updated from GPLv2 to GPLv3.^[3]

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, GPLv2-licensed BusyBox and BSD-licensed Toybox are available for use in embedded devices.
