title: Limit top command to only display top X processes on command line
body: <p>I'm not sure why there is not an option in the <code>top</code> command that does this, as it seems to be a natural request.</p>
  
  <p>If I pipe the output of <code>top</code> to <code>head</code>, then the list doesn't update and I get static output once. I could then bring the <code>watch</code> command into action, which would do the job. But, is there a simpler solution?</p>
