How to return the project to the state it was in before the files changed (to the last commit)?

Question

git

A task was done in the develop branch, then git add, git commit, and git push to the github repository.
Now I mistakenly added several dozen files, and some files have changed.
After that, I did not add, git commit, and git push. Therefore, I think it is possible if you return to the state of the last commit, the changed files will return to their previous state, and the new ones will disappear and there will be no files with modified status in git status. How to do it?

Answer 1

git reset --hard HEAD
