Runing RQM test scripts from command line?

I believe you're asking for a way to initiate a test script run from the command-line. So the test script and test case would have already been defined in RQM and you just want a way to kick it off.

RQM doesn't provide a command-line utility to do this, however I know there is a enhancement request for the RQM REST API to provide this function. The request is here:
