In a variable so that I can use it in a later computation. This is all a huge script that uses ssh to do a bunch of remote work. I need a single remote invocation to print some junk to stdout, and start a long running process that I will wait on. The goal is to pull the junk out of stdout, and on the basis of that, figure out what data I will send the long running process (it is listening on a seperate port).
