After running this command, you’ve successfully reverted your commit. Now that you’ve exited the terminal, you can finalize the process by running the command git push. Learn more about exiting this mode in this Stackoverflow answer. If you’re seeing this message in your terminal via Vim, you can use the command :wq If this file opens in your IDE, you can just close the file at the top. The goal for you is to review it and close the commit editor. It includes information about the commit that you’re reverting, including the author, the branch, the file, and the message. This is called a COMMIT_EDITMSG it holds a commit message of a commit in progress. You may see a message similar to the image below. You can learn more about git revisions here or on the git scm documentation. You can use any value that is considered a gitrevision, including the: You don’t have to use the commit hash to identify the commit you want to revert.Git is smart enough to identify the commit based on the first four (or more) characters. A shorter method is to run the command git revert 0a3d.Then I ran the following commands to add, commit, and push the changes.Įnter fullscreen mode Exit fullscreen mode In the image below, I added the words “hey, there” on line 1 of our index.md. I added a few arbitrary changes for the sake of the tutorial. Let’s commit and push some changes to our repository.In your repository, create a new file called index.md in our repository.Let’s recreate a situation where you need to undo a commit after you push. Enable you (and others) to understand the evolution of the codebase.Easily roll back small portions of your code if you make a mistake.fixed a typo in the codebase at this time.” It’s suggested to make frequent, small commits to: Imagine this: Git takes a “picture” of your codebase with information stating, “This is what your codebase looked like on Januat 3:55 pm. Running the command git commit saves a version of the codebase at that point in time. Git installed on your computer - You can find the instructions to install Git here.Ī commit is a snapshot of your repository.A GitHub account - If you don’t have one, you can find the signup instructions here.To follow along, you should already have: Some people may even have several years of experience, but still feel uncertain about reverting commits. As software engineers, we have to remember that easy is relative, and there is a steep learning curve in tech. Please refrain from adding discouraging comments critiquing those less experienced with version control. Please note that this post's target audience includes students, early-career developers, or folks who have less experience reverting commits. In this post, I will walk you through undoing a commit after you push your changes via the terminal. However, reverting your code isn’t always straightforward, especially when you’re still learning Git or gaining confidence navigating the command line. The -recursive option make git recursively do update -init under submodules in case these submodules also have submodules.One major benefit of version control is that you can roll back your code to any time in history without significantly disrupting your teammates. But this can fix many problems which leads to failures of simplying git reset. This will remove all submodules and reclone them again. If the method 1 does not work, we may use the second method by deinitalizing the submodules and reinitializing the submodules again. Method 2: Reset git submodules by deiniting and initing However, it may fail under some cases, especially after a merging which remove/add submodules. $ git submodule foreach -recursive git reset -hard This method is fast because it loops each submodule and runs git reset -hard within each modules. Method 1: Reset git submodules using foreach command In such cases, we may want to reset all submodules to the initial commit. However, there are cases where we would like “reset” the submodule, such as when we find updating a submodule repository will break the code tree, or merge some updates from others which update the submodules. Git submodule is a nice and convenient mechanism in Git to include the other Git repositories and manage the version/commit used from the submodule Git repository.
