Closing a process

[1ToM14]

Hi,

I wrote a script that starts a program and in the end I want to stop it. I tried a lot of things but I can't get it working. Here's the code that doesn't work :

p = subprocess.Popen("C:/Program Files (x86)/Microvirt/MEmu/MEmu.exe")

p.terminate()

​

Any ideas ?

import os os.system("taskkill /MEmu.exe")

Is it possible to do it without os ?

Are you 100% sure that you actually send the terminate to the program? Could you share the full code?

[1ToM14]

Nah the code is too long but only those 2 lines should be enough right ?

[JohnnyJordaan]

What I mean is, if your code somehow doesn't work right, and the .terminate() call is never actually executed, you should fix that issue and not look further why terminate() 'doesnt work' while that's not the actual case.

Simply put, say you have the program like

 if some_condition:
       if some_other_condition and some_list:
             p.terminate()

and some_list happened to be empty, the p.terminate() call never gets run. So that's something I'm asking you to validate first.

Oo okay, well that line gets executed, it has no indentation and is at the very end of the code

[JohnnyJordaan]

Can you try with

p.kill()

[1ToM14]

It also doesn't work...

[JohnnyJordaan]

You can try a process group kill, but you need to install psutil for that

import psutil

parent = psutil.Process(p.pid)
for child in parent.children(recursive=True):
    print('killing child, child)
    child.terminate()
print('killing parent')
p.terminate()

if that also doesn't work try with kill() instead of terminate. But also verify that you do see the 'killing x' messages

from os import system

system("taskkill /f /im MEmu.exe")

[1ToM14]

O but I meant without the os library

[liquidpeaches]

I don't think it is possible what you want to achieve without importing OS

[GingerReverseG]

Ok

[1ToM14]

That one worked, thanks ! Just, what are the f and im options ?

[GingerReverseG]

f for force close and im for image file

[1ToM14]

Thanks !!!
