Git Rebase

Rebase Overview

At its core, rebase is about doing one thing well in Git. Once you understand the pattern, you can apply it consistently across projects and teams.

Good rebase pays off across the whole project: fewer surprises, easier collaboration, and smoother onboarding. The snippet below is a solid starting point.

# replay your branch on top of the latest main
git switch feature/login
git fetch origin
git rebase origin/main

# after resolving any conflicts
git rebase --continue

Rebasing rewrites your commits on top of another branch for a linear, clean history.

Rebase Example

git add <files>
git commit -m "message"
git push origin <branch>

• Start from a minimal Rebase example and grow it only as needed.
• Keep things explicit so Rebase behaves the same for everyone on the team.
• Name things clearly so teammates understand your Rebase at a glance.
• Verify Rebase works as expected before relying on it in important work.

How Rebase Works in Git

Rebase builds on Git's model of snapshots and references. Every commit points to a full snapshot of your project, and branches are simply lightweight pointers to commits.

Rebasing rewrites your commits on top of another branch for a linear, clean history.

• The working directory, staging area, and repository are Git's three main areas.
• Commits are immutable snapshots linked to their parents.
• Branches and tags are just pointers to commits.
• Remotes are copies of the repository you sync with.

Practical Guidance for Rebase

On real teams, rebase works best with small, focused commits and clear messages. Commit often, write descriptive messages, and pull before you push to avoid surprises.

Common Mistakes

• Copying rebase commands or snippets without understanding what each part does.
• Skipping edge cases and error handling when using rebase.
• Not verifying the result of rebase before moving on.
• Over-complicating rebase before you actually need the extra flexibility.

Key Takeaways

• Rebase is a core part of working effectively with Git.
• Start small and keep rebase focused on a single goal.
• Apply consistent patterns so rebase scales across your project.
• Practise and document rebase to keep your workflow maintainable.
