title: Copy value from 1 column to another
body: <p>Here is a csv file in the linux system. This is one line from the file.</p>
  
  <pre><code>:/var/opt/data# vi data_2018_07.csv
  
  LGPAR,DATA,61543261,98747321900,gprs,464623201315531,NRI,1.45890,0.000000,0.0000,,2016-01-12 01:50:58,2016-01-12 15:50:58,0,11,0,0,0,0,25250,NO,NO,NO,1056.gz
  </code></pre>
  
  <p>Similarly, we have 10,000 line in that file. All we want to do is to add an incremental value (24th value) at a place between <code>NO,xxxx.gz</code> such as:-</p>
  
  <pre><code>LGPAR,DATA,61543261,98747321900,gprs,464623201315531,NRI,1.45890,0.000000,0.0000,,2016-01-12 01:50:58,2016-01-12 15:50:58,0,11,0,0,0,0,25250,NO,NO,NO,1, 1056.gz

  <p>Can we do that throughout the file for all rows using a small shell script? 
  Note: Rows are different in each row.</p>
