title: How to read a CSV file using shell script at granular level?
body: <p>My sample CSV file is:</p>
  
  <pre><code>test1,a=1,b=2  
  test2,c=3,d=4
  </code></pre>
  
  <p>I can get fields test1 a=1 b=2 using </p>
  
  <pre><code>while read f1 f2 f3  
  do
      echo $f1  
      echo $f2  
      echo $f3  
  done &lt; filename.csv  
  </code></pre>
  
  <p>but I want to read <code>a=1</code> separately and save <code>a</code> in param1 and <code>1</code> in param2. I want to do this for all the f2 &amp; f3 one by one.</p>
  
  <p>Could anyone help me in this?</p>
