title: Git command to know the Files changed of a Pull Request (PR) of a forked repository
body: <p>I have a GitHub repository which is forked by many other repository. One of such repository has made a pull request and wants to merge it with my repository(master) which i can clearly see in GitHub. </p>
  
  <p>I have a shell script which needs to make a CURL (Https POST) call against each files changed of the PR (the files changed will always have a Json content).The content of the files changed will act as a payload of the Curl call.</p>
  
  <p>Is there any git command to know the files changed and its content of the PR ?<a href="https://i.stack.imgur.com/nmxdG.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nmxdG.png" alt="As shown in the screenshot.
