7/1/2023 0 Comments Git rollback last commitThe main thing is to understand the difference between revert and reset. Now for the GUI question you had, you can prob right click on the commit you want to get back to ( reset) or remove the changes that one commit made ( revert) by right clicking a commit in the history tree or maybe theres a button to do it. this is DANGEROUS operation so be careful if you use it, you can change the state for other users of the repo. You can view and revert a previous commit, either published or unpublished. The original commit also remains in the repositorys history. Having dropped the previous commit, the repository state you want to change and re-commit would appear to be lostbut no: theres another copy of it in the. When you revert to a previous commit, the revert is also a commit. Prerequisites An existing project in Git Access to a terminal window/command line How to Revert Commit Git offers many features to manage your project from different historical commits. Reverting a commit in GitHub Desktop You can use GitHub Desktop to revert a specific commit to remove its changes from your branch. you are changing the history of the project => when you perform git push you need to use the -force/ -f flag. This guide shows you how to undo the last commit in git. reset: you will move the state of your repository history back in time and possibly lose all the changes that were made on top of that.you have not changed the history of the project but added to it => when you perform git push all is good this means you create a new node in the commit tree, i.e. revert: creates a new commit which is basically the opposite diff of the one created by the commit you are reverting (you'll see it in the automatic commit message).Regarding the part where you asked to get back to a older state there are 2 ways: That is the way git keeps track of your changes (and you can check it with the log command, or in the GUI tree view of the history, not sure how its called since i dont use GUI for git) git folder in the repository and assigns a hash to that change. To answer your 1st question: after you run the commit command the file gets saved on your hard disk a s a normal file, but git also saves the diff of the change in the. Make sure you only use it to get rid of commits that haven't been pushed to another repository! This can cause some serious headaches if any of those lost commits have been pushed to a public repository. Ī note of warning that git reset will alter history - if I made several commits and then reset to the first commit, the subsequent commits will no longer be in the commit history. With the -hard option, it replaces the contents of your working directory with what was on. If you want to set your branch to the state of a particular commit (as implied by the OP), you can use git reset, or git reset -hard The first option only updates the INDEX, leaving files in your working directory unchanged as if you had made the edits but not yet committed them. It's more or less a way to 'undo' a commit and save that undo in your history as a new commit. The above answer is not quite correct - git revert does not set your repository to that commit - git revert creates a new commit that undoes the changes introduced by commit.
