title: How can I sort a 10GB file?
body: <p>I'm trying to sort a big table stored in a file. The format of the file is
  (ID, intValue)</p>
  
  <p>The data is sorted by <code>ID</code>, but what I need is to sort the data using the <code>intValue</code>, in  descending order.</p>
  
  <p>For example</p>
  
  <pre><code>ID  | IntValue
  1   | 3
  2   | 24
  3   | 44
  4   | 2
  </code></pre>
  
  <p>to this table</p>
  
  <pre><code>ID  | IntValue
  3   | 44
  2   | 24
  1   | 3
  4   | 2
  </code></pre>
  
  <p>How can I use the Linux <code>sort</code> command to do the operation? Or do you recommend another way?</p>
