![]() HEAD~1 is telling git to roll back by 1 commit.Īnd that’s basically it. ![]() The next step is to clean up your master branch by using reset git reset -hard HEAD~1 Now your new branch has everything that is on your master branch. In fact, it should have been on a new branch - not the one where the work is currently on.įor example, you’ve got code on the master branch instead of its own feature branch.įirst, create the feature branch. You’ve committed some code but it’s on the wrong branch. You can use the hash before your deleted commit in reflog to roll back your delete. The reflog will list these actions in chronological order. It keeps track of things like checkouts, commits, cherry-picks, and resets. There is a tool called reflog - this keeps track of everything that happens, including deletions. At first, it felt like a good idea but now you want your commits back. You’ve done a git reset and now you’ve lost a few commits you didn’t want to lose. It just rolls back the file to the specific state. Now, if we run git status, it will show that we’ve restored that specific file to a previously saved state in the project.Īnother note to take is that this revert is currently not saved until you do so via a new commit. Take note that we are using - to tell git that we’re targeting a specific file and not an entire branch. Run the following git command: git checkout 02931ssa1 - nameoftargetfile.js Grab the git hash of the commit you want to roll back to. This will get only the commits where the specific file was changed. This is how you do it: git log - nameoftargetfile.js Here is how you roll back and reset a specific file to an older git commit.įirst, you need to look at the logs of that specific file. The rest of the repo is fine - just that one file you want to target. Someone has committed something strange to a file that was working at some point. How to reset a specific file to an older Git commit This means that no local changes will be preserved and will only be left with the files as it was saved at that particular point in time. The -hard flag makes sure that we have a clean working after this action. Then use the following command, followed by the target git commit. To do this, go into your git log, grab the hash of the commit you want to reset to. It also means that any commits that come afterward will disappear - sorta like it never happened in our commit history. This means that we’re setting our head pointer to a previous commit. You’ve done something you shouldn’t and now you want to restore your git commit to an older version. How to roll back and reset to an older Git commit Git will now create a new commit that will undo the changes as performed by that particular commit. Use this git hash as the reference point to which commit you want to revert. You can do this via revert, which will create another commit but with the reverted changes of the unwanted commit.įirst, use git log to bring up your previous commits. However, you want to revert a change done in C2 without deleting C3. Here, you have three distinctive commits. Let’s take a look at the commit flow below: C1 -> C2 -> C3 ![]() You want to revert a commit without deleting things in between. Use the following git command to achieve this: git reset -hard HEAD □ 5. You just want a clean start on the current branch you’re on. You can discard the change by typing 'y' for ‘yes’, or keep the changes by typing n for ‘no’.Īnd that’s basically it for keeping/deleting certain chunks or blocks of code in git. You get to chose which block of changes you want to keep or discard. This will take us into an interactive mode where git will go through every chunk of change that’s occurred in the file. You can also write it in longhand with -patch instead of -p. Here is how you can do it: git checkout -p index.js One thing is for sure - you don’t want to revert the entire file back to its original state. There are parts of the code you want to keep, while other parts you want to discard. Here is how you do it: git checkout HEAD accidentallydeletedfilename.js □ 3. You’ve deleted a file in git but want it back. What do you do? Use the following command: git checkout HEAD targetfilename.js □ 2. You’ve saved something but accidentally also included changes in a file you didn’t want to include. Discard all your local changes in a particular file Here are 10 ways you can undo your GIT mistakes. The point is that you’re not supposed to be making changes to the past once a change has been committed.īut accidents and unintended acts of GIT commits happen. In part, it’s because GIT is version control. GIT is fantastic when things go as planned - but not so much when it comes to undoing whatever mistake it is you made. We’ve all done it - deleted a file we shouldn’t have, merged things that aren’t supposed to be on the main branch, accidentally pushed up sensitive information, committing to the wrong branch…
