title: Ruby Command Line Options - verbose mode ON and placing code into Imput Loop
body: <p>Can any body tell how the below three options differs from each other in Ruby?</p>
  
  <p><strong><em>Part-I</em></strong></p>
  
  <ul>
  <li><strong>--verbose</strong></li>
  <li><strong>-v</strong></li>
  <li><strong>-w</strong></li>
  </ul>
  
  <p><strong><em>Part-II</em></strong></p>
  
  <ul>
  <li>-<strong>n</strong></li>
  <li>-<strong>p</strong></li>
  </ul>
  
  <p>All are doing the same job which is <code>verbose</code> mode <code>ON</code>. But logically how are they differs from each other?</p>
  
  <p>Thanks,</p>
