![]() How does it work? The ability to branch a project is crucial to modern Version Control Systems. Let’s first briefly discuss what a branch is in Git. And that’s what this material is about – how managing Git commands we can get rid of the results of our work by carelessly using something called a HEAD. It’s not the tool that can spoil the results of our work, but we are, when we use them in a wrong way. In the IT world, we use a variety of tools for our daily work, so let’s take this lesson to ourselves. Let’s not blame the tools, but rather look at ourselves to see if we are using them correctly! We are the ones who decide for which purposes to use a hammer – to break a window or put a nail into the wall. Do you agree with this suggestion, don’t you? After all, a tool only has certain characteristics and functionalities, but we are the ones who use it in some way or another. We benefit from them in a number of situations, but sometimes they still can cause some problems. However, be cautious when using it, especially with the -hard option, as it can discard changes in your staging area and working directory.There is a great variety of DevOps tools that serve different purposes and uses. Whether you need to unstage changes or revert to a previous state of your project, git reset provides the flexibility you need. Understanding how to navigate your project’s history using Git commands like `git reset HEAD` is crucial in managing your codebase. It will also modify your staging area and working directory to match the repository at the second last commit. This command will change the HEAD to point to the second last commit. In that case, you can use `git reset` with the `HEAD~n` syntax, where n is the number of commits you want to go back.įor example, if you want to go back to the second last commit, you can use: git reset -hard HEAD~2 Suppose you’ve made several commits but realize you want to go back to a previous commit. You can also use `git reset HEAD` to revert HEAD to a previous commit. The modifications will remain in your working directory. It simply removes the file from the staging area. Please note that `git reset HEAD` will not discard the changes in myfile.txt. This command will unstage myfile.txt, removing it from the list of files to be included in the next commit. To unstage this file, you can use git reset HEAD: git reset HEAD myfile.txt Imagine you have added a file to staging using git add: git add myfile.txtĪfter running this command, you realize you do not actually want myfile.txt in the next commit. If you’ve staged changes (with git add) that you no longer want to commit, you can use `git reset HEAD` to unstage those changes. The command `git reset HEAD` is used to unstage changes. Now that we understand git reset and the HEAD pointer, let’s dive into git reset HEAD. Hard: The -hard option will move HEAD back to another commit, updates the index, and modifies the working directory to match the repository at the specified commit.The -mixed option will move HEAD to another commit and also updates the index, but it leaves the working directory untouched. Mixed: This is the default mode when the git reset command is used without any option.It doesn’t touch the index or the working directory. Soft: Using the -soft option will move HEAD to another commit.The `git reset` command has three modes that dictate the state of the working directory and the staging area after the command is run. When you make a commit, the HEAD moves forward to this new commit. It’s a pointer that shows what you’re currently working on. The HEAD in Git is a reference to the last commit in the currently checked-out branch. It can move or “reset” the current HEAD to a specified state. The `git reset` command is primarily used to undo changes. ![]() Understanding Git Resetīefore we dive into `git reset HEAD`, let’s first understand git reset. In this article, we will focus on the `git reset HEAD` command, including its usage and examples. Among Git’s numerous commands, `git reset` is crucial for undoing changes. Git tracks changes in code bases, allowing developers to maintain a history of changes and revert back to previous versions if needed. In the world of software development, Git has become an essential tool for version control, helping teams collaborate on code more efficiently.
