title: how to grep exact match?
body: <p>I have a CSV file that is delimited by comma. I want to select by the second column that has the exact <code>"stringPattern"</code> </p>
  
  <p>I tried:</p>
  
  <pre><code>grep -w "stringPattern"
  </code></pre>
  
  <p>but it still gets any string that contains the string Pattern.</p>
  
  <p>What's the awk way to do this?</p>
