示例
c := exec.Command(name, arg...)
b := &bytes.Buffer{}
c.Stdout = b
c.Stdin = stdin
if err := c.Start(); err != nil {
return nil, err
}
timedOut := false
intTimer := time.AfterFunc(timeout, func() {
log.Printf("Process taking too long. Interrupting: %s %s", name, strings.Join(arg, " "))
c.Process.Signal(os.Interrupt)
timedOut = true
})
killTimer := time.AfterFunc(timeout*2, func() {
log.Printf("Process taking too long. Killing: %s %s", name, strings.Join(arg, " "))
c.Process.Signal(os.Kill)
timedOut = true
})
err := c.Wait()
intTimer.Stop()
killTimer.Stop()
