The GNU Core Utilities or coreutils is a collection of GNU software that implements many standard, Unix-based shell commands. See list. 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.
