title: How to output lines 800-900 of a file with a unix command?
body: <p>I want to output all lines between a and b in a file.</p>
  
  <p>This works but seems like overkill:</p>
  
  <pre><code>head -n 900 file.txt | tail -n 100
  </code></pre>
  
  <p>My lack of unix knowledge seems to be the limit here. Any suggestions?</p>
