04. Viewing Modified Files

We just looked at the --oneline flag to show one commit per line. That's great for getting an overview of the repository. But what if we want to dig in a little to see what file or files were changed by a commit?

What file or files are modified?

If you look in the repository at commit a3dc99a, it has the message "Center content on page".

What file or files were changed in this commit?
SOLUTION: There's no way to know for sure

git log --stat Intro

The git log command has a flag that can be used to display the files that have been changed in the commit, as well as the number of lines that have been added or deleted. The flag is --stat ("stat" is short for "statistics"):

$ git log --stat

Run this command and check out what it displays.
