![]() 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. ![]() 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. Note that this will also change the URL of the repository so anybody with access to this repo will need to update the remote url. N.B.: If you don’t get a response from this command when you use the -merge flag, don’t 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: In addition to the primary undo commands, we took a look at other Git utilities: git log for finding lost commits git clean for undoing uncommitted changes. ![]() 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. Attachments Options SourceTree can't tell that I selected a file. If I click 'Reset All', that works fine, but it's just a workaround for now. 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: If I commit the files I want to keep and click 'Discard' to rid my branch of the other (s), and then select the file (s) to discard, about half of the time ST claims I haven't selected a file (bad). 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. For projects created since then you may need to use 'main' instead, like: git reset -hard origin/main. Note - For users of github, 'master' was replaced with 'main' in October 2020. (2) Then reset the master: git reset -hard origin/master. In the Changed Files pane, right-click the file that you want to revert and select. To check for the hash, run git log or git reflog. For me the following worked: (1) First fetch all changes: git fetch -all. This results in a new commit that reverses the changes you want to undo. 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. 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. 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.īut 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.
