I don't think the return value of preexec_fn is used for anything. You
can use to do things like set process group IDs in the child. For your
use, everything needs to be args.
If you are using Python 2.5, and log is a file, you want:
from __future__ import with_statement
with log:
if machine != socket.gethostname():
command = "/bin/remsh %s %s" % (machine, command)
subprocess.check_call(command, shell=True, env=env,
stderr=subprocess.STDOUT, stdout=log)
The semantics are slightly different, since log will always close this
way, while in the other example, you have left it open if there is an
exception.
