Hello,
how can I achieve a behavior like tee in Python?
* execute an application
* leave the output to stdout and stderr untouched
* but capture both and save it to a file (resp. file-like object)
I have this code
proc = subprocess.Popen(shlex.split(cmd), stdout = subprocess.PIPE,
stderr=subprocess.STDOUT)
while True:
out = proc.stdout.readline()
if out == '' and proc.poll() != None:
break
sys.stdout.write(out)
logfile.write(out)
This works so far but always buffers a couple of lines and outputs
them en bloc. The final output is like it is desired but with a
significant delay. Is there a way around that?
Thanks,
Florian
