Hi folks,
I am trying to tee off both stdout and stderr from a process run
through Popen.
As a test, I am first trying to print the output below:
from subprocess import Popen,PIPE
...
p1 = Popen(['cvs', 'update'], stdout=PIPE, stderr=PIPE)
for (l1, l2) in zip(p1.stdout, p1.stderr):
print '-->' + l1,
print '-->' + l2,
This doesn't work - probably because I cannot iterate through the
pipes this way.
I am new to Python, and I'd appreciate it if you could please explain
why this
doesn't work and/or suggest an alternate way to redirect stdout and
stderr to a
common place.
My objective is for my code to print out stdout/stderr messages and at
the same
time redirect them to a log file.
Thanks
Mahesh
