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.
