Git Log

Once you’ve made several commits, it’s important to understand how to view and explore your project’s history. Git’s git log command gives you a detailed view of every commit that has been made.

What Does Git Log Do?

git log shows a chronological list of commits, including:

• The commit hash (unique ID)
• The author’s name and email
• The date and time of the commit
• The commit message

You may want to use git log to:

• Review the history of changes
• Find specific commits
• Understand the evolution of your project
