9.2. git log

git log is an extremely powerful tool to explore the history of a repository with some particularly useful option:

• --oneline shows a condensed view with each commit on a single line.

• --graph visualizes the commit history as a branching graph.

• --author="Author Name" shows commits made by a specific author.

• --since="2 weeks ago" displays commits made since a specific date, useful for reviewing recent changes.

• -p displays the patch (diff) introduced in each commit, allowing you to see what changes were made.

• --grep="keyword" filters commits to show only those with messages containing a specific keyword.
