title: Comparing file and printing the matches and differences
body: <p>I'm trying to compare 2 files and print the output like below:</p>
  
  <p>F1:</p>
  
  <pre><code>a|b|c|d|e|f|g
  q|w|e|r||f|
  </code></pre>
  
  <p>F2:</p>
  
  <pre><code>a|b|c|d|e|f|g
  q|w|e|r|t|f|u
  </code></pre>
  
  <p>output:</p>
  
  <pre><code>f1 - a|b|c|d|e|f|g - f2 - a|b|c|d|e|f|g  - All columns are matching
  f1 - q|w|e|r||f| - f2 - q|w|e|r|t|f|u - Column 5 and 7 are not matching
  </code></pre>
