Git Merge Combine multiple branch histories together. If you get conflict while rebasing resolve conflicts git add changes git rebase --continue When to use Git Rebase or Git Merge Choose Merge whenever we want to add changes of a feature branch back into the base branch.
This avoids all of the potential pitfalls of rebasing discussed below. On the other hand, this also means that the feature branch will have an extraneous merge commit every time you need to incorporate upstream changes.
As an alternative to merging, you can rebase the feature branch onto main branch using the following commands:. This moves the entire feature branch to begin on the tip of the main branch, effectively incorporating all of the new commits in main.
But, instead of using a merge commit, rebasing re-writes the project history by creating brand new commits for each commit in the original branch. The major benefit of rebasing is that you get a much cleaner project history.
First, it eliminates the unnecessary merge commits required by git merge. Second, as you can see in the above diagram, rebasing also results in a perfectly linear project history—you can follow the tip of feature all the way to the beginning of the project without any forks.
This makes it easier to navigate your project with commands like git log , git bisect , and gitk. But, there are two trade-offs for this pristine commit history: safety and traceability. Interactive rebasing gives you the opportunity to alter commits as they are moved to the new branch. Typically, this is used to clean up a messy history before merging a feature branch into main.
To begin an interactive rebasing session, pass the i option to the git rebase command:. This listing defines exactly what the branch will look like after the rebase is performed. For example, if the 2nd commit fixes a small problem in the 1st commit, you can condense them into a single commit with the fixup command:. When you save and close the file, Git will perform the rebase according to your instructions, resulting in project history that looks like the following:.
This is something that git merge simply cannot do. Once you understand what rebasing is, the most important thing to learn is when not to do it. The golden rule of git rebase is to never use it on public branches. For example, think about what would happen if you rebased main onto your feature branch:.
The rebase moves all of the commits in main onto the tip of feature. The problem is that this only happened in your repository. All of the other developers are still working with the original main. The only way to synchronize the two main branches is to merge them back together, resulting in an extra merge commit and two sets of commits that contain the same changes the original ones, and the ones from your rebased branch.
Needless to say, this is a very confusing situation. If you try to push the rebased main branch back to a remote repository, Git will prevent you from doing so because it conflicts with the remote main branch. But, you can force the push to go through by passing the --force flag, like so:.
This overwrites the remote main branch to match the rebased one from your repository and makes things very confusing for the rest of your team. Take the current one instead. Rebasing can be incorporated into your existing Git workflow as much or as little as your team is comfortable with.
The first step in any workflow that leverages git rebase is to create a dedicated branch for each feature. This gives you the necessary branch structure to safely utilize rebasing:. One of the best ways to incorporate rebasing into your workflow is to clean up local, in-progress features. By periodically performing an interactive rebase, you can make sure each commit in your feature is focused and meaningful.
Hence it is advised not to perform git rebase onto public branches. Thank you for reading it. I hope I have made git merge and git rebase commands clear. You may consider following me.
