I have a python script that needs to send control C to the mac

  • 0

I have a python script that needs to send control C to the mac terminal. I’ve tried sending the plain text “^C” but I get back that the terminal does not recognize the command. (The terminal meaning the pseudo terminal that python creates)

Basically, I am using the terminal to run an old Unix Executable and the only way that I can think of to terminate this gracefully is to send the interrupt signal. Is there any way I can fool the terminal into thinking that I pressed control C?

Thanks in advance!

    You can explicitly send the SIGINT signal to the process if you can get its PID using os.kill.

    os.kill(pid, signal.SIGINT)

    This will require you to instrument your script to grab the process PID, but it’s the best way to emulate the “ctrl-c” behavior.
