)

func main(){
	config := tail.Config{
		Location:    &tail.SeekInfo{Offset: 0, Whence: 2}, // Seek to this location before tailing
		ReOpen:  true,    // Reopen recreated files (tail -F)
		MustExist: false,      // Fail early if the file does not exist
		Poll:true,      // Poll for file changes instead of using inotify
		Follow: true, // Continue looking for new lines (tail -f)


	}
	t, err := tail.TailFile("./tail.log", config)
	if err != nil {
		fmt.Println("open file:",err)
	}
	for line := range t.Lines {
		fmt.Println(line.Text)
