When working with Git, it is common to make local commits to track changes in your codebase. However, there may be situations where you need to throw away or remove these local commits. This could be due to various reasons such as mistakenly committing sensitive information, committing unwanted changes, or simply wanting to start fresh. In this guide, we will explore two methods to throw away local commits in Git.
Method 1: Using git reset
One way to throw away local commits is by using the git reset command. This command allows you to move the branch pointer to a specific commit, effectively discarding any commits made after that point. Here's how you can use it:
1. Open your terminal or command prompt.
2. Navigate to the Git repository where you want to throw away the local commits.
3. Ensure that you are on the branch from which you want to remove the commits.
4. Run the following command:
git reset <commit>
Replace <commit> with the commit hash or reference to the commit where you want to reset the branch. For example, git reset HEAD~1 will reset the branch to the previous commit.
5. After running the command, Git will move the branch pointer to the specified commit, effectively removing any commits made after that point.
6. If you want to completely discard the changes from the removed commits, you can use the --hard option with the git reset command:
git reset --hard <commit>
Be cautious when using the --hard option as it will discard any changes made in the removed commits.
Using git reset allows you to throw away local commits without creating any new commits. However, keep in mind that this method alters the commit history, so use it with caution, especially when working in a collaborative environment.

Method 2: Using git revert
Another method to throw away local commits is by using the git revert command. Unlike git reset, git revert creates a new commit that undoes the changes made in the specified commit(s). This method is useful when you want to preserve the commit history while removing unwanted changes. Here's how you can use it:
1. Open your terminal or command prompt.
2. Navigate to the Git repository where you want to throw away the local commits.
3. Ensure that you are on the branch from which you want to remove the commits.
4. Run the following command:
git revert <commit>
Replace <commit> with the commit hash or reference to the commit you want to revert. For example, git revert HEAD will revert the most recent commit.
5. Git will create a new commit that undoes the changes made in the specified commit. It will open a text editor where you can add a commit message explaining the revert. Save and close the editor to complete the revert process.
6. Repeat the git revert command for each commit you want to throw away.
7. After reverting the commits, your branch will include the new revert commits that undo the changes made in the unwanted commits.
Using git revert allows you to throw away local commits while preserving the commit history. This method is safer in collaborative environments where altering the commit history can cause issues.

- Before throwing away local commits, ensure that you have a backup or a copy of any important changes that you may want to keep.
- If you want to throw away all local commits and start fresh, you can simply delete the branch and recreate it from the remote branch or another branch.
- It's a good practice to communicate with your team or collaborators before throwing away local commits, especially if you're working in a shared repository.
