Git Remove Last Merge Commit - Shell-Bash

Hey fellow programmers! Have you recently made a merge commit in Git that you regretted? Perhaps you made a mistake or merged some code that you didn't really need. No worries, because in this tutorial, we will be discussing how to remove the last merge commit in Git using Shell/Bash commands.

Step 1: Identify the Merge Commit

To remove the last merge commit, you first need to identify the commit hash of the merge commit that you want to remove. You can do this by running the following command:

git log --merges

This command will list down all the merge commits that have been made in the Git repository. Identify the hash of the commit that you want to remove.

Step 2: Revert the Merge Commit

Once you have identified the merge commit that you want to remove, you can revert it using the following command:

git revert -m 1 <commit-hash>

Note that the -m option specifies which parent of the merge commit you want to keep. In most cases, you would want to keep the changes from the branch that you merged in, so you should use -m 1. However, if you merged in a branch into the main branch, and you want to keep the changes from the main branch, you should use -m 2 instead.

Step 3: Push the Changes

After you have reverted the merge commit, you will need to push the changes to the remote repository to make them permanent. You can do this by running the following command:

git push

And that's it! You have now successfully removed the last merge commit from your Git repository.

Conclusion

Removing the last merge commit in Git can be quite simple if you know what you're doing. By following the steps outlined in this tutorial, you should be able to remove any unwanted merge commits from your repository in no time. Happy coding!
