During a rebase, you can run a few commands on commits to modify commit messages. These messages provide valuable insight into the project history. Stopped at 5d025d1. formatting You can amend the commit now, with git commit -amend Once you are satisfied with your changes, run git rebase -continue Multiple messagesĮach regular Git commit will have a log message explaining what happened in the commit. Changing committed filesĭuring a rebase, the edit or e command will pause the rebase playback on that commit and allow you to make additional changes with git commit -amend Git will interrupt the playback and present a message: You can learn more about interactive rebasing and additional rebase commands on the git rebase page. This gives you the opportunity to alter individual commits in the process, rather than moving all commits. In these or similar instances where it's important to preserve a clean project history, adding the -i option to git rebase allows you to run rebase interactive. Since your new commits will be replacing the old, it's important to not use git rebase on commits that have been pushed public, or it will appear that your project history disappeared. In standard mode, git rebase allows you to literally rewrite history - automatically applying commits in your current working branch to the passed branch head. To modify older or multiple commits, you can use git rebase to combine a sequence of commits into a new base commit. Amending a commit that is shared with another user will potentially require confusing and lengthy merge conflict resolutions. Be cautious when using -amend on commits shared with other team members. If there are no changes staged, a -amend will still prompt you to modify the last commit message log. You can add or remove changes from the Git staging area to apply with a -amend commit. To review, git commit -amend lets you take the most recent commit and add new staged changes to it. This is a confusing situation for developers to be in and it’s complicated to recover from. Avoid amending a commit that other developers have based their work on. This has the same consequences as resetting a public snapshot. Don’t amend public commitsĪmended commits are actually entirely new commits and the previous commit will no longer be on your current branch. The resulting commit will replace the incomplete one, and it will look like we committed the changes to hello.py and main.py in a single snapshot. The -no-edit flag will allow you to make the amendment to your commit without changing its commit message. # Edit hello.py and main.py git add hello.py git commit # Realize you forgot to add the changes from main.py git add main.py git commit -amend -no-edit We'll cover usage examples in the following sections. There are a few common scenarios for using git commit -amend. To Git, it will look like a brand new commit, which is visualized with an asterisk (*) in the diagram below. But, amending does not just alter the most recent commit, it replaces it entirely, meaning the amended commit will be a new entity with its own ref. It can also be used to simply edit the previous commit message without changing its snapshot. It lets you combine staged changes with the previous commit instead of creating an entirely new commit. The git commit -amend command is a convenient way to modify the most recent commit.

Changing the Last Commit: git commit -amend By the end of this tutorial, you'll be familiar with commands that will let you restructure your Git commits, and be able to avoid pitfalls that are commonly encountered when rewriting history. These options give you powerful work flow customization options. These mechanisms include: Commit -amend, git rebase and git reflog. Git has several mechanisms for storing history and saving changes. Git provides its history-rewriting commands under the disclaimer that using them may result in lost content. This includes letting you define exactly what your project history looks like however, it also creates the potential of losing commits. But it's also designed to give you total control over your development workflow. Git's main job is to make sure you never lose a committed change.
