Git has a few built-in stats you can get instantaneously. The git log command has different options, such as --numstat, that will show the number of files added and lines deleted for each file since each commit. However, for finding the top committer in the repository, we can just use the git shortlog command.

Getting ready
For all the examples throughout the book, we are using the jgit repository; you can either clone it or go to one of the clones you might already have.
Clone the jgit repository as follows:
$ git clone https://git.eclipse.org/r/jgit/jgit chapter6 $ cd chapter6
