This is a follow up to this question, but if I want to pass an argument to stdin to subprocess, how can I get the output in real time? This is what I currently have; I also tried replacing Popen with call from the subprocess module and this just leads to the script hanging. from subprocess import Popen, PIPE, STDOUT cmd = 'rsync --rsh=ssh -rv --files-from=- thisdir/ servername:folder/' p = Popen(cmd.split(), stdout=PIPE, stdin=PIPE, stderr=STDOUT) subfolders = '\n'.join(['subfolder1','subfolder2']) output = p.communicate(input=subfolders)[0] print output In the former question where I did not have to pass stdin I was suggested to use p.stdout.readline, there there is no room there to pipe anything to stdin. Addendum: This works for the transfer, but I see the output only at the end and I would like to see the details of the transfer while it's happening. Continue reading...
