Making sure a Python script with subprocesses dies on SIGINT

Question

I\'ve got a command that I\'m wrapping in script and spawning from a Python script using subprocess.Popen. I\'m trying to make sure it dies if the

Answer 1

I found a -e switch in the script man page:

-e      Return the exit code of the child process. Uses the same format
         as bash termination on signal termination exit code is 128+n.

Not too sure what the 128+n is all about but it seems to return 130 for ctrl-c. So modifying your cmd to be

cmd = [ 'script', '-e', '-q', '-c', "sleep 2 && (exit 1)", '/dev/null']

and putting

if p.returncode == 130:
    break

at the end of the for loop seems to do what you want.
