![]() Here's what the commit log looks like: git log -oneline I have already initialized the project and made three commits like we did in the last section. How to Revert to a Previous Commit Using the git revert Command Luckily for us, there is way to recover the state of a deleted commit. This will also change the commit history of your project. If you undo a commit and delete every file change that came after it, you might lose important changes made to your code by you and other teammates. Especially when you're working with a team. While this seems like something cool to do, you should be careful when using this command. When we check the commit log, we'll have just the first commit. All changes that were made to the file after that commit were deleted. We're back to the initial state of the file at the point of the specified commit. This is what the text file looks like now: 1. Let's test this out by reverting back to the first commit: git reset 89f6c3d -hard If you want to undo a commit and the all the changes made after that commit, you attach the -hard flag to your git reset command. ![]() We've successfully gone back to a previous commit. ![]() If you've followed up to this point, you'll not notice any difference in the file (you'll see how to undo both the commit and any changes made to the file later).īut when we run the git log -oneline command, the third commit wont't be in the log of commits: git log -oneline To go back to the second commit, you run the git reset command followed by the commit ID. In my terminal, I have this: git log -onelineĪs you can see above, this command lists all your commits along with their IDs. To do that, run the command below: git log -oneline To revert to a previous commit, you must first get the commit ID. We'll repeat the process above two more times but we'll add an extra line of text to the file before each commit. ![]() Next, we're going to initialize, add, and commit this file: git init To get started, I've created a file called tasks.txt. You'll then see how you can revert to either the last commit or any other commit using the commit ID. In this section, we'll go through the process of creating a new file and making three commits. How to Revert to a Previous Commit Using the git reset Command They are not exactly the same, though, so we'll make this article a bit more practical by demonstrating how each command works in a project.Īnyone can follow along with this tutorial because it's not going to be language specific - we'll make use of a text (txt) file. These commands can help you undo your commits and go back to a previous commit. The two commands we'll discuss in this article are git reset and git revert. In this article, you'll learn how to revert to previous commits when tracking your project with Git. It also makes collaborating with others more efficient. This will keep the history the same, and it will not change the record of the branch’s history.Git is a great tool for version control. You could also make a new commit that signifies exactly the same state of the venture as f414f31.Also, the commits you did after f414f31 will no longer be included in the history of your master branch. Yet, this is rewriting the history of your branch, so if you share your branch with anyone it is best to not use this option. This can be done with git reset –hard f414f31. You could make your current branch to point to the older commit instead.(You can find that via git log or by viewing any history browser.) You then have a few different choices dependent on what you would like to do: Here is another example, presume that the good commit that you want to go back to is f414f31. HEAD shows your current branch, or current commit, meaning that all git reset –hard HEAD will do is to throw away all of the uncommitted changes you have. Then it will make the files in the working tree and the index (“staging area”) the same as the versions committed in.Make your present branch (typically master) back to point at.When you want to revert to a past commit using git reset – – hard, add. For example, if you do git add to stage a newer version of the file, this will override the past staged version of the file in the staging area. But be sure to note that Git does not take track of changes to your files. When you have created a commit, which will have your project files stored in a particular state, they ae safe. Git records the state of the files when you stage them with git add or when you make a commit. Be sure to always double check that the output of git status is empty (clean) before you begin using it. Luckily there is an easy solution to follow to correct this.įirst of all git reset - hard is a very dangerous command because it eliminates all of your noncommitted changes. A question that comes up with developers is how to use git reset– hard HEAD to revert to previous commit.
