Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
pip3 --version (return code: 0)
pip 9.0.1 from /home/ubuntu/.local/lib/python3.6/site-packages (python 3.6)
pip3 --HELP (return code: 2)
pip <command> [options]
no such option: --HELP
