title: Comparing (diff) different files with same names in lots of directories and subdirectories
body: <p>I have the following directory structure in <code>LINUX</code></p>
  
  <p><img src="https://i.stack.imgur.com/ssxDv.png" alt="enter image description here"></p>
  
  <p>In every single folder (except home), there's a file called <code>myfile.xml</code></p>
  
  <p>I want to compare (preferably using <code>diff</code>) all of the <code>myfile.xml</code> files. So, I want the code to automatically go in all subdirectories (as deep as it goes) and look for <code>myfile.xml</code> and compare them. It can also compare all of the files to 1 of them. I cannot find how to do that.</p>
  
  <p>Thanks in Advance</p>
