    This is a good answer, certainly better than mine - I upvoted it. But the answer we ask for isnt always the answer we should get - thats why we're asking, because we dont know. It doesnt address the problem with your work flow that brought you head to head with this issue in the first place. I demonstrate how that might be mitigated in my own answer, and how single shell variable string arguments over 2mbs in length can be passed to newly execed processes with just a couple lines of shell script.
