I think what I actually meant was:
s = subprocess.Popen( ['ls','-la'], stdout=subprocess.PIPE )
while 1:
line = s.stdout.readline()
if not line:
break
logging.info( line )
The problem with p.poll() is that the process probably has ended
before you have gotten all the text out of the buffer. Readline will
return a falsy value when the process ends.
Anyway, this post has a lot of responses so I'm sure _something_
works :)
