how to go back to an old git comit code example
Example 1: how to revert a commit
git reset --soft HEAD@{1} # delete the last commit keeping the changes
git reset --hard HEAD@{1} # delete the last commit removing the changes
git push --force origin master # delete the last commit also on remote branch
Example 2: reset to commit
# This will detach your HEAD, that is, leave you with no branch checked out:
git checkout 0d1d7fc32
