You can use the os/signal package to handle incoming signals. Ctrl+C is SIGINT, so you can use this to trap os.Interrupt. c := make(chan os.Signal, 1) signal.Notify(c, os.Interrupt) go func(){ for sig := range c { // sig is a ^C, handle it } }() The manner in which you cause your program to terminate … Read more

SIGTERM tells an application to terminate. The other signals tell the application other things which are unrelated to shutdown but may sometimes have the same result. Don’t use those. If you want an application to shut down, tell it to. Don’t give it misleading signals. Some people believe the smart standard way of terminating a … Read more
MSDNs Unix Code Migration Guide has a chapter about Win32 code conversion and signal handling. Although Microsoft has decided to archive this brilliant guide, it is very useful. Three methods are described: Native signals Event objects Messages
A class based clean to use solution: import signal import time class GracefulKiller: kill_now = False def __init__(self): signal.signal(signal.SIGINT, self.exit_gracefully) signal.signal(signal.SIGTERM, self.exit_gracefully) def exit_gracefully(self, *args): self.kill_now = True if __name__ == ‘__main__’: killer = GracefulKiller() while not killer.kill_now: time.sleep(1) print(“doing something in a loop …”) print(“End of the program. I was killed gracefully :)”)
