title: How can I summarize the changes users have made in git?
body: <p>Is there one command that I can use to summarize all the changes (i.e., number of commits, number of insertions and deletions) users have made in a repo? I have used <code>git shortlog --no-merges -sn</code> to see the number of commits but I'd like to include the number of insertions and deletions as well. I do not want to specify a specific author to be summarized.</p>
  
  <p>UPDATE: The reason I don't want to specify authors is that I want to be able to run a script on multiple repos without any intervention.</p>
