Understanding Git Commits
Git is a powerful version control system that allows developers to track changes in their codebase over time. At the heart of Git are commits, which represent snapshots of your project at a specific point in time. Understanding how Git commits work is crucial for effectively managing your project's history and collaborating with others.
What is a Git Commit?
A Git commit is a record of changes made to your project's files. When you make changes to your codebase and want to save those changes, you create a new commit. Each commit has a unique identifier, called a commit hash, which is a long string of letters and numbers that uniquely identifies the commit.
Anatomy of a Git Commit
A Git commit typically consists of the following elements:
- Author: The person who made the changes and created the commit.
- Committer: The person who actually committed the changes to the repository.
- Commit Message: A brief description of the changes made in the commit.
- Timestamp: The date and time when the commit was created.
- Diff: The changes made to the files, represented as a set of additions, modifications, and deletions.

Viewing Git Commit History
You can view the commit history of your project using the git log
command. This will show you a list of all the commits in reverse chronological order, with the most recent commit at the top.

The output of the git log
command will include the commit hash, author, commit message, and timestamp for each commit.
Navigating Git Commits
Git provides various commands for navigating and working with commits, such as git checkout
and git revert
. These commands allow you to move between different commits, undo changes, and manage the project's history.
By understanding the basics of Git commits, you'll be better equipped to manage your project's history, collaborate with others, and recover from mistakes. In the next section, we'll explore how to revert the latest Git commit.
