title: Processing comma separated values using a loop in Unix
body: <p>I have a file which contains values like:</p>
  
  <pre><code>CA, PA, NY
  ND, MO, MI
  </code></pre>
  
  <p>I need to process these values one by one. The flowchart will be as follows:</p>
  
  <pre><code>Enter loop -&gt; Process CA; Process PA; Process NY -&gt; Other commands -&gt; Process ND; Process MO; Process MI -&gt; End;
  </code></pre>
  
  <p>Is this possible using shell scripting?</p>
