Hi!
I'm currently writing a script which launches external programs, but it
keeps leaving zombie/defunct processes behind, until I kill the
launching script, which is a bit of a pain, as it's supposed to be a
daemon. The code I'm using is:
newPid = subprocess.Popen( cmdLine, executable=cmdLine,
close_fds=True ).pid

I am trying to modify a programming example and I am coming up with
two problems... first is that I can't seem to pass along the
arguments to the external command (I have been able to do that with
the old module and cmd is the command I wish to try) all the output
seems to be returned as one line (at least when I run the program in
spe).

Hi all,
Consider this scenario, where in I need to use subprocess to execute a
command like 'ping 127.0.0.1' which will have a continuous non-
terminating output in Linux.
# code
# This hangs at this point.
How should I handle these kind of commands (ping 127.0.0.1) with

Hi,
I've used subprocess with 2.4 several times to execute a process, wait
for it to finish, and then look at its output. Now I want to spawn
the process separately, later check to see if it's finished, and if it
is look at its output. I may want to send a signal at some point to
kill the process. This seems straightforward, but it...

Hi,
i'm trying to call subprocess.popen on the 'rename' function in
linux. When I run the command from the shell, like so:
rename -vn 's/\.htm$/\.html/' *.htm
it works fine... however when I try to do it in python like so:
p = subprocess.Popen(,stdout=subprocess.PIPE,stderr=subprocess.PIPE)
print p.communicate()

You should call os.waitpid() after killing the child process, to let the
OS free the resources allocated to it.

Hi. I wondered if anyone knew the rationale behind the naming of the
Popen class in the subprocess module. Popen sounds like the a suitable
name for a function that created a subprocess, but the object itself is
a subprocess, not a "popen". It seems that it would be more accurate to
just name the class Subprocess, can anyone explain why this...

Hello,
I am attempting to use Popen() in a Windows service. I have a small
Win32 .exe that I normally run through the os.popen2() function. I've
written a class to work with the input and output parameters that are
passed and captured from this exe. When I use the class outside of a
service using either subprocess.Popen or os.popen2 work...

Hello,
I'm launching a script as follows:
<code>
p = subprocess.Popen()
p.wait()
</code>
If p.py writes to sys.stdout, then it is shown on the console.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
