title: Can vim monitor realtime changes to a file
body: <p>My question is similar to this <a href="https://stackoverflow.com/questions/18632/how-to-monitor-a-text-file-in-realtime">how to monitor a text file in realtime</a>
  but I want to do it in vim. I know I can read an opened file use <code>tail -f sample.xml</code> file, and when new content is written to the file, it'll also write the new content to my screen. Can I have vim automatically fill the new data when a file is updated?</p>
