• git reset --soft HEAD^ Undo last commit, put changes into staging

• git reset --hard HEAD^ Undo last commit and all changes

• git reset --hard HEAD^^ Undo last 2 commits and all changes

• git commit --amend where amend means add to the last commit. Sometimes we forgot to add files to commit. for example abc.txt file was forgot, we can add as follows: git add abc.txt and git commit --amend -m "New commit message"

Note: we don't have rollback and undo on this exact name either verbs or option.
