![]() ![]() git reset HEAD~2 (Tells git to drop the last two commits).git reset 899679c (Requires you to locate the commit hash from the log).One way to do this is to run one of the two commands: Let's say we have a history log that looks like the image below and we want to undo the last two commits and go back to the third commit. not pushed up your changes to a remote branch) and you want to undo those changes. Git reset is best used when you have only made local commits (i.e. Once a reset is applied, all the changes before the specified commit are no longer a part of the history for a branch. The git reset command provides a way to reset a project back to a specified commit. Use revert if you have a remote branch with commits and you want to undo a commit while still keeping things in sync and retaining the git history.Use reset if you have only made local changes and you do NOT have a remote branch.Although they have similar-sounding names, there are slight nuances to be aware of when deciding which option to go with. In order to properly explain this topic, it's important to understand the distinction and differences between reset and revert. And now you can merge branch B to branch A.Have you ever made some revisions to your code, committed those changes, and then wished you could undo the changes you just committed? Perhaps you pushed up some code to a remote branch for a feature you are working on and then realized that you want to remove the changes and go in a different direction? In this article, I will cover how to undo the mistakes □ that we inevitably make as developers. 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. So the git history will be like A - B - C - E - F - E' (branch A) 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. The parent-B branch is merged into the parent-A branch. 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. And changes made by E is no longer present in the working directory. 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. ![]()
