        fmt.Println(err)
        return
    }
    si, err := st.Tail(filepath, tailLine, func(content string) {
        fmt.Print(fmt.Sprintf("get content: %s", content))
    })
    if err != nil {
        fmt.Println(err)
        return
    }
    time.AfterFunc(time.Second*10, func() {
        si.Close() // close the acquisition channel after 10 s
