	defer readerCloser.Close()

	t := time.Now()
	go func() {
		var buff [20]byte

		tick := cmd.Tick()
		for {
			select {
			case <-time.After(time.Second * 5):

				cmd.Cancel()
				return
			case <-cmd.Done():
				fmt.Println("timeout", time.Since(t))
				return

					return

		}
	}()

	err := cmd.Run()
	if err != nil {

	fmt.Println("since", time.Since(t), cmd.Status())
	time.Sleep(time.Second)
	return
