If you want to see the (easy) CLI commands (external programs) do:
echo %PATH%
Then for each path in the PATH variable do:
dir <PATH>
substituting the path from the PATH variable for <PATH>. You can execute any program from any directory if you use the complete (absolute) path of the program (executable, binary).
