![]() ![]() To start, you’re going to need to run a git stash command to protect any local changes within your working copy. However, there are a few hidden gotchas in this deceptively simple command that you should definitely know about before proceeding. All you need is the git reset command, and you can get right back on track with your work. Undoing a merge you just made in your local environment is one of the easier operations of this type that you can perform. Īll those operations create a new commit that you can push to your remote, as needed. Even better, once changes have been made, you can revert the revert itself by referencing its id in git revert. The -m 1 option specifies the parent (branch) number as the one you want to keep, and the hash value directs git to the exact point you would like to revert to. To undo a merge in Git once it has been pushed, you can use: Revert can be used to roll back a single commit or a full merge as needed. Luckily, Git is more than capable of doing this (and more) with the revert command. Once your merge has been pushed out to a remote branch, it can become a bit more complicated to undo on a technical level as Git must reconcile more changes and differences than it had to in your local environment. The other two commands mentioned above should each have their place in your repertoire to facilitate local and remote merge undoing, respectively. However, that does not make it suitable for all Git merge undo emergencies. Using git merge -abort after a bad merge can help you escape a problematic conflict resolution process. You’ll need to either stash or commit any floating changes before you go through with a merge abort to avoid losing important work. Uncommitted worktree changes that were there when the merge process first began can actually end up lost for good if you’re not careful. This can be a grand thing or a bit of a problem in its own right, depending on your needs and project guidelines. ![]() So long as your work has not been committed, you’re free to abort your last merge without leaving much of a trace. It makes for a perfect solution just after you’ve typed git merge at the most inopportune moment imaginable. For example, git merge -abort actually allows you to stop a merge in its tracks once you’ve discovered it has troublesome conflicts. Aborting a merge ❌Įach of these commands has its strengths and weaknesses, not to mention its own gotchas to reason about before you start using it. Sometime, break-up is the best thing to do.įirst of all, you should know that there are three commands that you can turn to in order to get Git back the way you want it after a messy or otherwise incorrect merge operation. Let’s look at all of the things you should be aware of to make your next merge catastrophe go away. ![]() Undoing a merge is a multifaceted process, but it does not need to be particularly complicated. To merge is one thing to undo a merge is another. To learn how to handle this important part of Git project management, keep reading. You can end up hopelessly lost and confused about choosing the best command or technique to preserve important work while minimizing the effects of mediocre merge results-especially without the right information on the topic. There are multiple ways to do many things in Git, and merge reversals are no exception. That’s precisely why every Git-using dev should be well-versed in undoing bad merges, both locally and remotely. A bad merge can detract from your project’s historical continuity, confuse fellow contributors, and potentially slow down development for all involved. Merging makes this all possible.īut merging can also make for a mean headache if you make a mistake. Without merging, your codebase would wither as contributors come up empty-handed when it comes time to mix their work in with what has already been published. Merging is essential to every developer's workflow in Git. ![]()
