Reset file to master git1/25/2024 You can learn more about Git in this video or article. Then you can push that commit to the remote repository as you wish. You can do this with the standard commit command: $ Git commit -m 'commit message' It is essential to know that when you revert, you'll need to commit the changes again (the reverted changes). In this article, you have learned how to revert a file to a previous commit with the git checkout command. Use this only if you are sure and don’t want those unsaved local changes. Git will replace the file with the specified committed version. Just make sure you want to revert a file before doing so, because you will discard your current local changes to the file. So now that you know how to get the SHA code, you can use the git checkout command to revert your file to any commit you want by also passing the file name or file path: $ git checkout da9cc5f - README.md How to Revert a File to a Previous Commit You will use the SHA hash to revert your file: 198d425 (HEAD -> main) initial This will return only commits for the specified file and the commit SHA hash followed by the commit message. In a situation where the file is located in another folder, you can either navigate your terminal to the folder or use the file path in the command as seen below: $ git log - oneline src/App.js To do this, add the file name to the command: $ git log - oneline README.md If you want to revert a particular file to a previous commit, you must first see all commits made to that file. Using this command alone would return all commits made on that project. Note: The oneline option displays the output as one commit per line. It will discard commits or clear the changes that were not committed. This command will show a list of all commits you have made in your projects to all files and their hash codes:īut a more straightforward command to use is the command below, where you attach the oneline option: $ git log - oneline The git reset command is used for: Returning the overall working tree to the previous committed state. The best method is to use the command below in your terminal: $ git log There are many ways to get each commit's SHA and details. Then we'll see how to revert a file to a previous commit. Let’s start by first learning how to locate all previous commits and their SHA hash. If you are in a rush, here is the command: $ git checkout SHA-HASH - file/file-pathīut suppose you are not in a rush. There are many possible approaches, but in this article, you will learn the best approach, the git checkout method. Reverting the file is a much cleaner way to handle it. Manually changing each line of code in your file to its original state or a specific commit state and doing a new commit can lead to a messy commit history. Or you discover a situation that requires you to revert to a previous commit, like a strange bug. Suppose you have made a lot of commits and later realize that your current version of changes is wrong. When working with Git, you often commit your changes and then push them to a remote repository. This is up in GitHub, so we can check it out there, as well.Git is a version control system that helps teams and individuals track and record changes made to a file or an entire project. Let's push this up to GitHub before we make any more mistakes. We used reset -hard both to get rid of this commit by resetting to this commit, but also to recover it again from the ref log. If we do a git log oneline, we can see that we have our regular commits, and then we have the take three commit back on as master. We want to reset master to this commit to recover it so we can take the hash and we can git reset -hard back to that hash. Rough log will work to save commits but only if they haven't been garbage collected by Git yet. Now, we want to recover this commit here, this take three commit, but one thing to note is that this commit, because we reset hard, is now abandoned and will actually get garbage collected eventually if we don't save it. For example, you can see the three latest resets that we've done and this last one was the reset hard. For that, we're going to use git rough log which is a really powerful way to look at all the different things you've done in your local Git repository. We really want to get that function back so let's take a look at how we might do that. Instructor: We just did a git reset -hard back one which removed our function from app.js.
