title: How to add specific string after a set of value
body: <p>For example, i have the file with following entries:-</p>
  
  <pre><code>10.59.37.9      strvasr5267
  10.59.37.11     strvasr5268
  10.59.37.15     strvasr5279
  10.59.37.16     strvasr5303
  </code></pre>
  
  <p>and i want to add  <code># "TRENDS:*,netstat:netstat|netstat1|netstat2|netstat3"</code> after each hostname like:- </p>
  
  <pre><code>10.59.37.9  strvasr5267   # "TRENDS:*,netstat:netstat|netstat1|netstat2|netstat3"
  </code></pre>
  
  <p>Is there any loop in which i can read both ip's and hostname and then add above string after hostname...</p>
