title: How to ignore white spaces in awk command
body: <p>I have a file user_list.txt which has a table of 4 fields separated by ",". For eg,</p>
  
  <pre><code>hi,hello,good morning,bye.
  </code></pre>
  
  <p>I'm using the below command to extract the third column field.</p>
  
  <pre><code>output=$(awk 'BEGIN { FS = "," } ; { print $3 }' user_list.txt) 
  </code></pre>
  
  <p>When i try to check the contents of the output variable.,</p>
  
  <pre><code>echo ${output[0]} --&gt; good
  echo ${output[1]} --&gt; morning
  </code></pre>
  
  <p>I want it as a string 
  <code>echo ${output[0]} --&gt; good morning</code>, but since whitespace is the default separator, the string is being split.</p>
  
  <p>Please help.</p>
