git reflog [command] [options]

git reflog records when refs (like HEAD and branch tips) are updated, providing a safety net for recovering lost commits. After accidental resets, rebases, or branch deletions, the reflog shows where refs previously pointed, allowing recovery of otherwise unreachable commits.
Entries in the reflog expire after a configurable period (default 90 days). The reflog is local only and is not shared between repositories.
