title: How to find the difference between multiple files
body: <p>I have an application installed in 20 linux servers. The application contains multiple configuration files such as.</p>
  
  <pre><code>/etc/config_1/config_1_1.cfg
  /etc/config_1/config_1_2.cfg
  /etc/config_2/config_2_1.cfg
  /etc/config_2/config_2_2.cfg
  /etc/config_3/config_3.cfg
  </code></pre>
  
  <p>I will have all these configuration files in all the servers. Now, I wanna compare and find the difference between the config files in all the servers.</p>
  
  <p>Eg:
  Compare <code>/etc/config_1/config_1_1.cfg</code> between server1, server2 and server3  etc..</p>
