Debugging can be frustrating, especially when a bug appears in a large codebase and you have no idea when it was introduced. Instead of manually sifting through commits, Git Bisect can help you track down the exact commit that introduced the bug efficiently. In this blog, we’ll explore how Git Bisect works, walk through a...
Git is one of the most widely used version control systems, and knowing how to use it efficiently is essential for developers. If you’re preparing for a job interview, expect Git-related questions to come up, whether you’re a beginner or an experienced professional. In this detailed guide, we’ll explore the most commonly asked Git interview...
If you’ve been working on a project and decided to uninstall and later reinstall Git on your Windows machine(There are many reasons; mostly, we do it due to corrupted installations, upgrade issues, configuration errors, switching installation methods, or problems with path/environment variables), you might encounter some unexpected issues when trying to push or pull from...
Git, the distributed version control system, is a powerful tool that allows developers to manage and track changes in their projects efficiently. Despite its robustness, developers sometimes find themselves needing to undo a commit, either due to a mistake, a change in requirements, or other reasons. Git provides several ways to revert changes, and one of the common methods is using the git revert command. In this blog post, we will explore how to use git revert to undo the last commit and understand its implications.
Let’s say we are working on your code in Git and something didn’t go as planned. So now we need to revert our last commit. How do we do it? Let’s find out!
revert command will create a commit that reverts the changes of the commit being targeted. means here git will create a new commit that contains reverted changes so that we will maintain commit history in the shared repository.git revert <commit name to revert>
Example :
— -> commit 1 — → commit2 — → commit c1
git revert c1
— -> commit 1 — → commit2 — → commit3 — → commit reverting c1
2. reset Command — the reset command to undo your last commit. So be careful. it will change the commit history, it will move the HEAD of the working branch indicating commit and discard anything after.
we use the reset command with two options
a. The --soft option means that you will not lose the uncommitted changes you may have.
git reset --soft HEAD~1
b. If you want to reset to the last commit and also remove all unstaged changes, you can use the --hard option:
git reset --hard HEAD~1
This will undo the latest commit, but also any uncommitted changes.
we should really only use reset if the commit being reset only exists locally. This command changes the commit history and it might overwrite the history that remote team members depend on.
revert instead creates a new commit that undoes the changes, so if the commit to revert has already been pushed to a shared repository, it is best to use revert as it doesn’t overwrite commit history.
Undoing the last commit using git revert is a safe and effective way to manage mistakes or changes in your Git project without altering the commit history. It promotes collaboration by preserving the commit history’s integrity and allows for seamless integration with subsequent changes. Understanding the implications of git revert empowers developers to make informed decisions when managing their version-controlled projects.
