        The agent has more command-line options than shown here.
        Download the agent and run it without arguments to
        see all options.

        <b>Tip</b>: Run the above command locally in a similar shell (for instance in a
        docker container) then try to connect to the shell using the commands below. If that
        works, then you are all set.

              NOTE: When running the agent on windows, an exit of the remote session using
              exit in powershell or command prompt does not terminate the shell completely.
              To terminate the client ssh session must be killed by closing the terminal.
              Cleanup of remote processes on the agent appears to work properly despite this
              problem. It is just that exit of the windows shell (powershell or command prompt)
              is not detected properly.
