  <p>The best I got so far was by using a simple:</p>
  
  <pre><code>awk 'BEGIN { FS = "\\\\" } ; {print $SELECTED AREA}'
  </code></pre>
  
  <p>where the selected area would be $4 if it is possible to set the field separator as "\\" without considering the "\"</p>
  
  <p>Is someone have an idea how to do that?</p>
