A Guide To Undoing Mistakes With Git

We'll be looking at in this two-part series: how to undo mistakes using Git. In this first article, we will look at various mistakes — and how to safely undo them with Git!

No matter how experienced you are, mistakes are an inevitable part of software development. But we can learn to repair them! And this is what we’ll be looking at in this two-part series: how to undo mistakes using Git.

Working with code is a risky endeavour: There are countless ways to shoot yourself in the foot! But if you use Git as your version control system, then you have an excellent safety net. A lot of “undo” tools will help you recover from almost any type of disaster.

In this first article of our two-part series, we will look at various mistakes — and how to safely undo them with Git!

Discard Uncommitted Changes In A File

Suppose you’ve made some changes to a file, and after some time you notice that your efforts aren’t leading anywhere. It would be best to start over and undo your changes to this file.

The good news is that if you haven’t committed the modifications, undoing them is pretty easy. But there’s also a bit of bad news: You cannot bring back the modifications once you’ve undone them! Because they haven’t been saved to Git’s “database”, there’s no way to restore them!

With this little warning out of the way, let’s undo our changes in index.html:

$ git restore index.html

This command will restore our file to its last committed state, wiping it clean of any local changes.
