Terminate applications opened with "subprocess.Popen()"?

Question

I want to view an image in Eye of Gnome (eog), and then have it automatically close later. I am not very well versed in subprocess, but so far I have tried:

eog = subprocess.Popen('oeg <some file>', shell=True)
# ...Code, Code, Code...
eog.kill()

or

eog.terminate()

Neither work. Any help?

Answer 1

Do not use shell=True, example:

import subprocess, shlex
command = 'eog <filename'>
eog = subprocess.Popen(shlex(command))
..code..
eog.kill()
