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). 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 (less functionality), or license. For example, BusyBox which is licensed under GPL-2.0-only, and Toybox which is licensed under 0BSD.
In 1990, David MacKenzie announced GNU fileutils.[5]
In 1991, MacKenzie announced GNU shellutils and GNU textutils.[6][7] Moreover, Jim Meyering became the maintainer of the packages (known now as coreutils) and has remained so since.[8]
In 2002, Meyering announced GNU coreutils as a merger of the earlier packages textutils, shellutils, and fileutils, along with some other miscellaneous utilities.[3]
