I still think you want to use communicate(). Like this: p = subprocess.Popen(args,stderr=subprocess.PIPE,stdout=subprocess.PIPE) output, err = p.communicate() That's it. No need for a loop, or manually handling the fact that stderr and/or stdout could end up with a full buffer and start to block. -- Jerry
