title: How to identify renamed files in pre-commit hook
body: <p>I need differentiate the renamed files from list of committed files in per-commit hook.</p>
  
  <p>for example,
  I have check out a directory which contains the more number of files. I renamed some of the files, deleted some of the files, modified some of the files, Added some of the files &amp; committed the folder.</p>
