推荐答案

 ^ C 不会发生代码>.您可以做的是拦截发送到您的过程的信号，这样您就可以干净地结束了.

The subprocess should continue to run after your process ends, as long as it ends cleanly, which won't happen if you hit ^C.
What you can do is intercept the signals sent to your process so you can end cleanly.
sigchan := make(chan os.Signal, 1)
signal.Notify(sigchan,
    syscall.SIGINT,
    syscall.SIGKILL,
    syscall.SIGTERM,
    syscall.SIGQUIT)
go func() {
    s := <-sigchan
    // do anything you need to end program cleanly
}()
