And now you can merge branch B to branch A. The above command will revert the E’ commit. To do this, you have to revert the ‘revert commit‘. Because it is been reverted in E’.Īssume after sometimes, you have made some changes to branch B and now you are fine with merging that branch. In the above example, you can’t merge branch B to branch A again. You have to revert the ‘revert commit‘ if you need to merge back the branch. Reverting a merge commit means you are inverting all the changes from the merge branch so that you can’t merge the branch again. Because this approach won't rewrite existing commit history, it's suitable for reversing changes made by commits that were pushed and are in use by others. Undo the changes made by a shared commit by creating a new commit that reverses the changes. So the git history will be like A - B - C - E - F - E' (branch A) Revert a branch to a prior state by resetting it to a previous commit. To jump back to a previous commit, first find the commits hash using git log. This will revert all commits from the merge branch. You have to mention the parent branch number. And if you run git revert E then git will throw a warning. In this above case, E is the merge commit. So when you are reverting a merge commit you have to specify whether you need to revert changes of the parent-A branch or the parent-B branch. Use git checkout & the ID (in the same way you would checkout a branch) to go back: git checkout <. The parent-B branch is merged into the parent-A branch. Go back to the selected commit on your local environment. When there is a merge there are two branches included.

Reverting a merge commit is somewhat tricky.

In this case, the git history is very clean and everyone reading the git history will understand that the particular commit has reverted for some reason. This is one of the advantages of git revert.

then you can push this new commit, which undid your previous.

But you can see that in the git history commit E is also present. So you need to pass the commit you need to revert.Īnd after reverting E the commit history will be changed as below A - B - C - D - E - E'Į’ is the reverted commit. Git revert will always take a commit hash. You have decided to go with the git revert. So you have decided to undo the changes that E did. But unlike other undo commands, git revert will introduce a new commit that has the inverted changes.įor example, consider the below git history A - B - C - D - EĪssume, E is the bad commit and you no longer need those changes. The git revert command is used to ‘undo‘ the changes you have made in the past.
