9/12/2023 0 Comments Git discard changes to fileThe staging area (index) is a container where Git gathers all changes which will be part of. For more information, refer to How to Stash Git. It happens that you modify a file in your local working directory and sometimes wish just to discard the committed changes. To discard the changes before staging and committing, use the git checkout command. For example, after working on a few files, you realize that you want to revert the changes made to one specific file. Hopefully, this post has helpful information for you. How to Discard Unstaged Changes in Git There are three options in Git that help to undo your local changes. When using Git, it is common to make changes that you want to remove entirely before the staging phase. You can even reset a file you've already staged. You can also reset a file to a specific commit or branch, depending on your needs. In this post, we've seen how you can reset a single file in your local repository to any commit or branch you have. From the question, the asker may be quite happy with his current set of ignored files. Also, git clean -f -d is probably a better opposite of adding a new untracked file. Once that's done, you can run your usual git checkout command to reset the file to the latest version of the same branch. When you are ready to actually delete, then remove the -n flag: Note: git reset -hard removes staged changes as well as working directory changes. Keep in mind, however, that you cannot undo this git restore index.html Another interesting use case is to restore a specific historic revision of a file: git restore -source 7173808e index.html git restore -source master2 index. To do so, use the git reset command: git reset HEAD README.md If you want to discard uncommitted local changes in a file, simply omit the -staged flag. When you've staged a file already, like running this command: git add README.md You can also specify a branch to reset to, rather than a commit hash on the same branch: git checkout - README.mdįor example: git checkout origin/master - README.md Reset a Stage File To specify a commit, add it to the git checkout command: git checkout - README.md Specify a Branch Maybe you don't want the latest but instead a specific commit. This will reset any changes you've made to the file since the last commit. Let's say our file was called README.md and we want to reset it to the latest version of the same branch: git checkout - README.md To reset a single file, simple use the git checkout command. In this post, we'll learn how to reset the state of a single file in your local repository to any commit or branch you have. More specifically, sometimes you only need to replace a single file. In this tutorial, well see how to discard changes in our working directory that are not in the index. But you did not ask how to do that, so let's not confuse things more.Sometimes you make a mistake and need to reset some changes in your local repository. How do I discard changes in my working copy that are not in the index git version-control Share Follow edited at 8:42 Mateen Ulhaq 24. Overview A Git working directory can contain different types of files including staged files, unstaged files, and untracked files. Maybe instead you'd like the superproject to record the submodule's current commit. (The fact that the submodule is on the "wrong" commit is suggestive though: it means that maybe you don't want to force the submodule back to the superproject's recorded commit. Sometimes this behaviour is useful even in newer versions of Git that support the above commands. which removes all uncommitted changes, including the uncommitted merge. The git submodule command has a lot of modes the update -checkout mode says using the current superproject commit, find the $hash value, and then run the above git -C command to check out that commit within the submodule. This is older syntax but does the same as the above. Where do you get that hash ID? Well, the easy way is to let Git fish it out for you, by running: git submodule update -checkout MyApp/mylib Where $hash is the hash ID that the superproject (i.e., your current commit in your repository) is calling for. To force the submodule back to the commit that the superproject calls for, you need to have Git itself run: git -C MyApp/mylib switch -detach $hash If you want to discard this type of changes, you can use the git restore command: git restore index.html. They exist in your Working Copy, but you havent wrapped them in a commit, yet. The modified (new commits) status really just means that the submodule is currently "on" a different commit than the superproject calls for. Changes that havent been committed to the local repository are called 'local' changes in Git.
