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 Template:Mono 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.

Commands

Currently, there are over 100 commands implemented by coreutils, with the commands 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.

History

In 1990, David MacKenzie announced GNU fileutils.[1]

In 1991, MacKenzie announced GNU shellutils and GNU textutils.[2][3] Moreover, Jim Meyering became the maintainer of the packages (known now as coreutils) and has remained so since.[4]

In September 2002, the GNU coreutils were created by merging the earlier packages textutils, shellutils, and fileutils, along with some other miscellaneous utilities.[5]

In July 2007, the license of the GNU coreutils was updated from GPL-2.0-or-later to GPL-3.0-or-later.[6]

On April 2026, Canonical is planning to replace the standard, C-based coreutils package with one written in Rust in their release of Ubuntu 25.10 and 26.04 LTS.[7] A preview version of the package is currently available, though some complain about performance and security issues.[8]
