title: Shell script to get dynamic values of fields
body: <p>I have a output file with content:</p>

  </code></pre>
  
  <p>I need to extract only the last two fields..LGCC and GCC.
  But the values are generated dynamically. so can not extact them by delimeter space. How can I get this two values? what ever be the values be?</p>
  
  <p>the output should be:</p>
  
  <pre><code>LGCC                 GCC
  CMS Final Remark     No GC
  </code></pre>
