title: Changing column value in CSV file
body: <p>In csv file I have below columns and I try to change the second column's value with <br/>
  <code>awk -F ',' -v OFS=',' '$1 { $2=$2*2; print}' path/file.csv &gt; output.csv</code>. <br/>

  <p>output.csv</p>
  
  <pre><code>"sku",0,"supplierName"
  "sku",0,"supplierName"
  "sku",0,"supplierName"
  "sku",0,"supplierName"
  </code></pre>
