If one uses subprocess.Popen(args, ..., shell=True, ...) When args finishes execution, does the shell terminate? Either way seems problematic.
If it does not terminate, then it seems as if calls like wait and communicate would never return. It also seems the subprocess would never die, and that most of the examples with the shell True would leave processes lying around. If it does terminate, then how can you stuff new commands down the pipe to the subprocesses stdin? Does this module contemplate receiving multiple commands for the shell to execute? I'm also unsure of the semantics of the pipes for the processes standard file handles. Do they need to be closed (judging from the examples, no)? When reads/writes to them return, and what state is the stream in at the time? Thanks for any wisdom you can offer. Ross Boylan -- http://mail.python.org/mailman/listinfo/python-list
