How to terminate a python subprocess launched with shell=True

Question

I\'m launching a subprocess with the following command:

p = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True)

However, when I try t

Answer 1

p = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True)
p.kill()

p.kill() ends up killing the shell process and cmd is still running.

I found a convenient fix this by:

p = subprocess.Popen("exec " + cmd, stdout=subprocess.PIPE, shell=True)

This will cause cmd to inherit the shell process, instead of having the shell launch a child process, which does not get killed. p.pid will be the id of your cmd process then.

p.kill() should work.

I don't know what effect this will have on your pipe though.
