What’s happening: git reset rewinds your repository’s history all the way back to the specified SHA. Scenario: You’ve made some commits locally (not yet pushed), but everything is terrible, you want to undo the last three commits-like they never happened. Be sure you know what you’re throwing away here! (Maybe use git diff to confirm.) Reset “local” changes They were never committed, so Git can’t help us recover them later. Keep in mind: any changes you “undo” this way are really gone. You could provide a branch name or specific SHA you want to go back to or, by default, Git will assume you want to checkout HEAD, the last commit on the currently-checked-out branch. What’s happening: git checkout alters files in the working directory to a state previously known to Git. You want to undo everything in that file-just go back to the way it looked in the last commit. You haven’t committed those changes, though. Scenario: The cat walked across the keyboard and somehow saved the changes, then crashed the editor. With nothing currently staged, this just rewrites the previous commit message.

What’s happening: git commit -amend will update and replace the most recent commit with a new commit that combines any staged changes with the contents of the previous commit. Undo with: git commit -amend or git commit -amend -m "Fixes bug #42" Scenario: You just typo’d the last commit message, you did git commit -m "Fxies bug #42" but before git push you realized that really should say “Fixes bug #42”. This is Git’s safest, most basic “undo” scenario, because it doesn’t alter history-so you can now git push the new “inverse” commit to undo your mistaken commit. If the old commit is “matter”, the new commit is “anti-matter”-anything removed in the old commit will be added in the new commit and anything added in the old commit will be removed in the new commit. What’s happening: git revert will create a new commit that’s the opposite (or inverse) of the given SHA. Scenario: You just ran git push, sending your changes to GitHub, now you realize there’s a problem with one of those commits. In this post, I’m going to take a look at some common scenarios where you might want to “undo” a change you’ve made and the best way to do it using Git. When you make a new commit, Git stores a snapshot of your repository at that specific moment in time later, you can use Git to go back to an earlier version of your project. In Git, “undo” can mean many slightly different things. To select what files to see and how they are sorted, use the comboboxes above the Files view.One of the most useful features of any version control system is the ability to “undo” your mistakes. The Files lists avoid table headers to save screen space and avoid width configuration. To operate on secondary items, like refs, you can use the context menu. Thus, we have simplified this in the Standard window - toolbar buttons and menu items work on the most important item.

In the Working Tree and Log windows the selected view affects on what Git data a command works (for example, Rename may work on a branch or on a file) this has turned out to be a constant source of confusion. Some toolbar buttons like "Local Files" and "Push" show a number badge to indicate local changes or pushable commits.
The left part of the toolbar is constant for all categories. The Graph display changes for each category and the toolbar shows the most relevant commands for this category. managing my feature branches (My History), checking out other branches or looking for tags (All Branches+Tags), managing stashes (Stashes) or finding old commits (Reflog). You can use the two leftmost toolbar buttons to switch between the Local Files and Graph user interface (mode).Įach mode is separated into different categories by the left selector.Įach category focuses on different tasks, e.g. When using Git there are two types of workflows: working with local files and working with the commit Graph (history).īoth types require to work with different Git data, need different commands and ideally different user interfaces.
