title: How parsing works for unix commands: "rm" and "cp"
body: <p>We are executing below commands</p>
  
  <pre><code>rm -f $folder_name/filename*
  
  cp $folder_name1/filename1* $folder_name/
  </code></pre>
  
  <p>After checking the execution log we get following command executions</p>
  
  <pre><code>rm -f '/home/user/file*'
  
  cp /home1/user1/file1* /home/user/
  </code></pre>
  
  <p>Why <code>rm</code> executes with a single quote and not <code>cp</code> command?</p>
