title: Processing csv file using shell script
body: <p>I have a csv file with fields:
  'file path', 'line no', 'description'.  For example:</p>
  
  <pre><code>/home/user/file.txt,121,xxxx
  </code></pre>
  
  <p>The csv file has many entries. 
  How do I parse fields file path and line no and store them? 
  After I parse the file path I have to open the file in a Linux machine  and <code>grep</code> for a particular string. 
  Can someone give me an idea how to do it? </p>
  
  <p>Steps are:</p>
  
  <ol>
  <li>Open csv file.</li>
  <li>Find file name and line number.</li>
  <li>Open that file and line number.</li>
  <li>Grep for some pattern.</li>
  <li>Continue steps 2,3,4 in that csv file.</li>
  </ol>
