Once you move your changes to the Staging Area, you can confirm them by committing them locally. The Commit History contains a snapshot of all your work as commits. The state of our project now becomes: The Commit History Our second file, file2.txt, still remains in the Working Directory. Git highlights file1.txt in green, indicating that it’s inside our Staging Area. Let’s check the status of our project now: command to move all your changes to the Staging Area. Let’s add one of our files ( file1.txt) to the Staging Area using the following command: We can use the add command here to tell Git which files it needs to track for commits. Here’s a visual representation of the current state of our project: The Staging AreaĪfter you make changes in your Working Directory, you move them to a pre-commit area to tell Git that your changes are ready to be committed. Git marks them as “Untracked files,” highlighting them in red and representing them as changes in your Working Directory. Our Working Directory consists of two text files, each having the word “Hello” inside it. ![]() Next, let’s check the status of our project by running: $ echo hello>file1.txt $ echo hello>file2.txt Let’s create two simple text files inside our directory with some text inside them: This Working Directory represents the current state of your project on your code editor. Git manages and tracks the state of our project using three trees: the Working Directory, the Staging Area or Staging Index, and the Commit History. $ mkdir git-reset-examples & cd git-reset-examples & git init Create a new directory and initialize an empty Git repository inside it: To clearly understand how git reset works, let’s do a quick refresher on Git’s internal state management. I’ll walk you through some use cases of the reset command and different ways you can implement it, along with a few examples. It can be a tad bit tricky to grasp, so I’ll demystify some underlying concepts for you in this post. You can use Git to travel back in time and safely undo your changes in a project through a command called git reset. Git may indeed dominate version control today, but it has a popular feature that many developers still don’t fully understand. This is up in GitHub, so we can check it out there, as well.When it comes to version control systems in software development, Git is the most widely used- by far. Let's push this up to GitHub before we make any more mistakes. We used reset -hard both to get rid of this commit by resetting to this commit, but also to recover it again from the ref log. ![]() If we do a git log oneline, we can see that we have our regular commits, and then we have the take three commit back on as master. ![]() We want to reset master to this commit to recover it so we can take the hash and we can git reset -hard back to that hash. Rough log will work to save commits but only if they haven't been garbage collected by Git yet. Now, we want to recover this commit here, this take three commit, but one thing to note is that this commit, because we reset hard, is now abandoned and will actually get garbage collected eventually if we don't save it. For example, you can see the three latest resets that we've done and this last one was the reset hard. For that, we're going to use git rough log which is a really powerful way to look at all the different things you've done in your local Git repository. We really want to get that function back so let's take a look at how we might do that. Instructor: We just did a git reset -hard back one which removed our function from app.js. ![]()
