To get metadata like e-mail addresses for each author performing commits to our repository
Use different parameters with git log, which enables us to:
Skip the specified number of commits while displaying log entries
Extract data from commit logs within a date range
Search for a string value across commit messages to identify commits
Additionally, we have also learned how to clean our repository in case we or anybody else has messed it up by injecting files into it that do not belong there.
Not only that, we also saw, in practice, how to mark the milestones of our repositories' content using annotated and lightweight tags.
