The big table below, represents the core overlapping utilities from the following projects, and can be used to quickly see what's available where, as well as being a quick index to the online manuals for each command.

ProjectLicence(s)Description
GNU/LinuxGPLv3/GPLv2GNU/Linux is structured as separate projects (and licences)
POSIX Standarization effort
FreeBSDBSDThe FreeBSD distribution
busyboxGPLv2Reimplementation of standard GNU/Linux utils, targetted at embedded systems
toolboxApache2/MIT/BSDAndroid reimplementation of these standard utilities
Mac OS XBSDBased closely on FreeBSD

This is not an exhaustive list of commands and is based on the union of POSIX and the associated GNU/Linux projects. Developer oriented tools are excluded, since these aren't as widely used or distributed. Also excluded are commands always implemented as shell builtins.

Another interesting comparison is the mooted BusyBox replacement based on toybox. This proposed replacement was contemplated only to avoid the GPL, but it seems sense has prevailed.
