Think of git revert as a get out of jail free card whenever you make a mistake while collaborating on a project. Here is the take-away with the -hard and -merge flags while using them to undo a merge: the -hard flag removes uncommitted changes, while the -merge flag keeps uncommitted changes. Git revert is a source code control command typically known as a way to undo commits in Git, but it goes beyond that. In this article, you learned how to undo a merge in Git, so you can undo a mistaken or unwanted merge and work more efficiently with Git. N.B.: If you donât get a response from this command when you use the -merge flag, donât worry, it works. You can also use the HEAD keyword with the -merge flag by running git reset -merge HEAD~1: To undo a merge with the -merge flag, run git reflog to see the hashes of commits, then run git reset -merge previous-commit: Since the methods discussed above will revert uncommitted changes, Git provides a safer flag which is -merge. Note that when you use the -hard flag to undo a merge, any uncommitted change will be reverted. If you are not sure of the hash of the last commit, you can run git reset -hard HEAD~1 to go back to the commit before the merge: You should see some things get removed from your code editor when you run the command. When you get the hash of the commit you want to get back to, run git reset -hard commit-before-the-merge: ![]() git reflog is a better option because things are more readable with it. To check for the hash, run git log or git reflog. You can use the Git reset command to undo a merge.įirstly, you need to check for the commit hash (or id) so you can use it to go back to the previous commit. hard is too dangerous, and it might delete your files. Usually I have only one commit to rollback in which case using git reset HEAD on line 1 is a simpler way to rollback just one commit. But since you didnt move newBranch, it still points to. Then using git reset you moved the master pointer back two commits. Mitigation - git reflog can save you if you need it. When you made newBranch, you simply made a new pointer to the last commit. You'll be asked to enter a name for your new branch and once you hit enter, voila. 6 Answers Sorted by: 285 Edited Answer - edited over time to be more helpful Caveat Emptor - Destructive commands ahead. Using Emacs' git porcelain Magit, you can do this simply by hitting b s (magit-branch-spinoff). in tortoise git, we can view the history, and click on the 3rd from last commit, and chose 'reset master to this' which we are guessing means revert to this version. 1) git checkout master 2) git branch master 3) git reset -hard 4) git push -f origin master.So, in this article, I will show you how to undo a merge in Git so you can revert to the last commit you made. Git command to undo the last commit/ previous commits: Warning: Do Not use -hard if you do not know what you are doing. we want to undo the last 2 commits which were both pushed to origin master. When you finish working with a branch other than main, you'll want to merge it with the main so the feature or bug fix you just integrated will be reflected.Ä«ut what if you finish merging and realize you forgot to do one more thing? Or what if you accidentally merge when you are not ready to? ![]() ![]() Branching is an integral part of Git because it lets you work without tampering with code that's already in production.
