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.
ssh-agent -V (return code: 1)
version: No such file or directory
ssh-agent (return code: 0)
SSH_AUTH_SOCK=/tmp/ssh-qHb3i4LexZaP/agent.21920; export SSH_AUTH_SOCK;
SSH_AGENT_PID=21922; export SSH_AGENT_PID;
echo Agent pid 21922;
