This document is inspired by - Thank you. If you have the master branch checked out locally, you can also do it in two simpler steps: First reset the branch to the parent of the current commit, then force-push it to the remote. Where git interprets x^ as the parent of x and + as a forced non-fastforward push. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32: git push origin +dd61ab32^:master Let's say we have a remote origin with branch master that currently points to commit dd61ab32. The git revert command is considered as an undo command and reverts the changes introduced by the commit and adds a new commit with resulting reversed content. git revert Ībout History Rewriting Delete the last commitĭeleting the last commit is the easiest case. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. 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.Sometimes you may want to undo a whole commit with all 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. N.B.: If you don’t get a response from this command when you use the -merge flag, don’t worry, it works. Undo Commits Undo last commit putting everything back into the staging area: git reset -soft HEAD Add files and change message with: git commit -amend -m. 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. 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.
