rebase

rebase — To rebase means to move or re-apply a series of commits from one branch onto another branch, typically to integrate recent changes and create a linear commit history.

In simple English

In Git and other version control systems, rebasing is a way to update your branch with the latest changes from another branch, usually the main or develop branch. When you rebase, Git takes all the commits you made on your feature branch and replays them on top of the target branch. This creates a cleaner, linear project history compared to merging, which creates merge commits. Rebasing is especially useful when working on a feature branch that has fallen behind the main branch due to other team members pushing code. However, rebasing changes commit history, so it should only be used on branches that have not been shared publicly or with other team members, as it can cause conflicts and confusion if others are working on the same branch.

Say it like this

  • We need to rebase this branch before merging.
  • Let's rebase onto main to get the latest changes.
  • I'm going to rebase my commits to clean up the history.

Use it at work

Before merging

  • Please rebase on main before I review.
  • I rebased and fixed the conflicts.

Being careful

  • Don't rebase a shared branch.
  • After a rebase, you'll need to force push.

Explaining

  • Rebasing keeps the history clean.
  • Use interactive rebase to squash commits.

Don't say this

✕I rebased my code with the team branch.
✓I rebased my branch onto the team branch.

Rebase is directional: you rebase X onto Y, meaning you update X with changes from Y.

More about rebase

Real examples(3)

  • in a standup

    "I finished the feature, but I need to rebase it onto main first before I submit the PR."

  • in a code review

    "Please rebase your branch on the latest develop branch to resolve these merge conflicts."

  • in a team meeting

    "We're using interactive rebase to squash commits and create a cleaner git history."

More mistakes(2)

Handle with care. Non-native speakers sometimes confuse rebase with merge. Rebase rewrites commit history by moving commits; merge combines branches while keeping history intact.

  • ✕We should rebase instead of merge to keep the team synchronized.
    ✓We should merge shared branches, and only rebase local branches before submitting PRs.

    Rebasing rewrites history, so it should not be used on shared or public branches.

  • ✕I will rebase the main branch with my feature.
    ✓I will rebase my feature branch onto main.

    You rebase your work onto the target branch, not the other way around, to avoid overwriting shared history.

Other forms(4)

  • rebase verb

    "I will rebase my branch this afternoon."

  • rebasing verb

    "Rebasing your feature branch helps keep the commit history clean."

  • rebased verb

    "She rebased her commits before pushing to the remote."

  • rebase noun

    "A rebase is cleaner than a merge for local branches."

Often used with(5)

  • rebase onto · Specifies the target branch: rebase onto main, rebase onto develop
  • interactive rebase · A rebase mode allowing you to edit, squash, or reorder commits
  • rebase conflict · A merge conflict that occurs during the rebase process
  • force push after rebase · Common action needed after rebasing to update a remote branch
  • rebase and merge · A GitHub/GitLab feature that combines rebasing and merging in one action

Similar words(2)

  • merge · Similar goal but different method; merge preserves history with a merge commit, rebase rewrites history linearly
  • fast-forward merge · A simpler merge strategy that can achieve similar results to rebase in some scenarios

Questions(5)

What does rebase mean in software engineering?
Rebase is a Git operation that takes commits from one branch and replays them on top of another branch. It is used to update your feature branch with the latest changes from the main branch while maintaining a clean, linear commit history.
When should I use rebase instead of merge?
Use rebase on local or personal branches before sharing your code. Use merge when working with shared branches like main or develop. Rebase is safe for unpublished work but should not be used on branches that other team members are actively using.
What is interactive rebase?
Interactive rebase is a rebase mode where you can edit, reorder, squash, or delete commits before replaying them. It is useful for cleaning up your commit history before submitting a pull request.
Is rebase formal or informal?
Rebase is a neutral, technical term used in both formal and casual contexts in tech workplaces. It is standard vocabulary in code reviews, pull request discussions, and team meetings.
What is the difference between rebase and merge?
Merge combines two branches and creates a merge commit, preserving all history. Rebase rewrites history by replaying commits on top of another branch, creating a linear history. Rebase is cleaner but should only be used on unpublished branches.
