Using shell=True also sets startupinfo to hide the window.
Thanks a lot Oscar and Eryksun for all the explanations and answers, I
really appreciate.

Hello,
I can't understand why the command below works with os.system but not with
subprocess.Popen (on windows, recording video with FFMPEG.exe)
cmd=('ffmpeg -f dshow -i video="%s" -f dshow -i audio="%s" -q 5

os.system(cmd)

I'm working on a program that calls another program recursively - this other
program reads in ini file and processes it; my program creates a number of
slightly different ini files and calls the other program for each one.

Popen may be a better call for what you're trying to do. Some of the
higher numbered popens will give you the stderr stream. The lowered
numbered ones are probably all you need.

With what can I try and see what the PID is when using popen() or popen2() ?
One thing that I noticed now is that when using popen() and the
sys.exit(). The command is completed before my Python shell is
terminated and if I use popen2(), sys.exit() works immediately but the
ping command runs st

Thats almost certainly because ping never reads its input.
In that case
If I use popen2, I need to write to one of the tuple parts.
>>> f = os.popen2('ping 192.168.8.85 -c 100 > cap1.txt')
>>> f[0].write('\x03')
Thank command works, but 'f[1]' is in read-only mode and I can't write
to it.
My command in the background is still not terminated.
BTW I use Linux as OS.

Yes potentially, but you still need to mess about with process ids etc
to find which process to send the signal... And you would have to do
the two things in separate threads since system() blocks your main program.

Its not possible with os.system because os.system runs the c
Even if you could send a break signal, it would go to a new shell that
os.system() invokes...
Perhaps you know or can get the ID of the process you want to signal, a
ctrl-c in a shell is equivalent to a SIGINT sent using os.kill()
