remove commits from branch code example

Example 1: git remove commit

# Removes latest commit from the stash, KEEPS changes
git reset --soft HEAD~

# Removes latest commit from the stash, DELETES changes
git reset --hard HEAD~

Example 2: git remove commits from branch after push

git reset --hard <last_working_commit_id>
So we must not reset to the commit_id that we don't want.

Then sure, we must push to remote branch:

git push --force

Example 3: delete commit

git checkout master
git reset --hard e3f1e37
git push --force origin master
# Then to prove it (it won't print any diff)
git diff master..origin/master
