Git reset
- Mixed reset (default): discard untracked files, but the changed files are preserved but not marked for commit.
- Hard reset: Resets the index and working tree. Any changes to tracked files in the working tree since
commit are discarded.
- Soft reset: Does not touch the index file or the working tree at all (but resets the head to
commit)
git reset --hard <SHA> # Reset git history to a specific commit
git reset HEAD~ # Reset state to the previous commit (~)
