GNU Core Utilities
The GNU Core Utilities or coreutils is a collection of GNU software that implements many standard, Unix-based shell commands. The utilities generally provide POSIX compliant interface when the POSIXLY_CORRECT environment variable is set, but otherwise offers a superset to the standard interface. For example, the utilities support long options and options after parameters. This environment variable enables a different functionality in BSD.
Similar collections are available in the FOSS ecosystem, with a slightly different scope and focus (less functionality), or license. For example, BusyBox which is licensed under GPL-2.0-only, and Toybox which is licensed under 0BSD.
The commands implemented by coreutils are listed below. Throughout this article and customary for Unix-based systems, the term file refers to all file system items including regular files and special files such as directories.
In 1990, David MacKenzie announced GNU fileutils.
In 1991, MacKenzie announced GNU shellutils and GNU textutils. Moreover, Jim Meyering became the maintainer of the packages (known now as coreutils) and has remained so since.
In September 2002, the GNU coreutils were created by merging the earlier packages textutils, shellutils, and fileutils, along with some other miscellaneous utilities.
In July 2007, the license of the GNU coreutils was updated from GPL-2.0-or-later to GPL-3.0-or-later.
