Of course, as with everything, there are multiple solutions.

But what I would usually do in this case in order to undo my latest commit and then commit my new changes is the following.

• Let’s say that you made some changes and you committed the changes:

git commit -m "Committing the wrong changes"  

• After that if you run git log you will see the history of everything that has been committed to a repository.

• To undo the last commit, just run the following:

git reset --soft HEAD~1

The above command will reset back with 1 point.

Note: the above would undo your commit but it would keep your code changes if you would like to get rid of the changes as well you need to do a hard reset: git reset --hard HEAD~1

• After that make your new changes

• Once you are done with the changes run git add to add any of the files that you would like to be included in the next commit:

git add .

• Then use git commit as normal to commit your new changes:

git commit -m "Your new commit message"

• After that, you could again check your history by running:

git log

Here’s a screenshot of the process:

Another approach would be to use git revert COMMIT_ID instead.

Here is a quick video demo on how to do the above:

Hope that this helps!
