title: Grep for value in string over x milliseconds
body: <p>I know how to <code>grep</code> and find all the lines in a file that contain a simple string:</p>
  
  <pre><code>cat my_log.log | grep 'Completed 200 OK in'
  </code></pre>
  
  <p>That returns results similar to the following:</p>
  
  <pre><code>various info... Completed 200 OK in 250ms various info...
  various info... Completed 200 OK in 112ms various info...
  various info... Completed 200 OK in 1000ms various info...
  various info... Completed 200 OK in 6000ms various info...
  various info... Completed 200 OK in 33ms various info...
  various info... Completed 200 OK in 100ms various info...
  </code></pre>
  
  <p>I'd like to take it a step further and only return the lines where the milliseconds (ms) is <em>over</em> 1000. </p>
  
  <p>Is this possible with grep?  Other posts suggest using <code>sed</code> but I'm curious if it is possible to do this with <code>grep</code>. </p>
