title: Comparing two files in Unix
body: <p>I have got 2 files which have got n number of lines.
  eg: File 1</p>
  
  <pre><code>465466454
  546545454
  5454454
  Data=4545454545484848484
  kuh uytyer huihkuh
  </code></pre>
  
  <p>File 2</p>
  
  <pre><code>e4654sdfdsf
  544hjklhjl
  464jku
  Data=4545454545484848484
  kuh uytyer huihkuh
  </code></pre>
  
  <p>As you can see both files have got the same data after the place "Data=" (this "Data=" occurs only once in the file)</p>
  
  <p>So i need to cut the lines that are before the "=" sign and then compare these two files and then get an output stating if these 2 files are equal in a csv format file.</p>
  
  <p>Its not just one file but it will be many files in 2 different folders and every first file in one folder needs to be compared with the first file in the another folder and so on.. </p>
