Killing a process created with Python's subprocess.Popen() [duplicate]

This question already has answers here: How to terminate a python subprocess launched with shell=True (11 answers) Closed 8 years ago.

Here is my thought:

First of all, I created a process by using subprocess.Popen

Second, after certain amount of time, I tried to kill it by Popen.kill()

import subprocess
import os, signal
import time

proc1 = subprocess.Popen("kvm -hda /path/xp.img", shell = True)
time.sleep(2.0)
print 'proc1 = ', proc1.pid
subprocess.Popen.kill(proc1)

However, "proc1" still exists after Popen.kill(). Could any experts tell me how to solve this issue? I appreciate your considerations.

Thanks to the comments from all experts, I did all you recommended, but result still remains the same.

proc1.kill() 开发者_C百科#it sill cannot kill the proc1

os.kill(proc1.pid, signal.SIGKILL) # either cannot kill the proc1

Thank you all the same.

And I am still waiting for your precious experience on solving this delicate issue.

In your code it should be

proc1.kill()

Both kill or terminate are methods of the Popen object. On macOS and Linux, kill sends the signal signal.SIGKILL to the process and terminate sends signal.SIGTERM. On Windows they both call Windows' TerminateProcess() function.

process.terminate() doesn't work when using shell=True. This answer will help you.

Only use Popen kill method

process = subprocess.Popen(
    task.getExecutable(), 
    stdout=subprocess.PIPE, 
    stderr=subprocess.PIPE, 
    shell=True
)
process.kill()

How about using os.kill? See the docs here: http://docs.python.org/library/os.html#os.kill
