How to Recover Lost Commits With git reflog

git reflog records every position HEAD has pointed to, letting you recover commits that seem lost after a reset, rebase, or branch deletion.

Key points

• Even commits no longer reachable from any branch usually still appear in the reflog for a while
• Find the commit hash you need in the reflog output, then git checkout <hash> or git branch recovery <hash> to restore it
• The reflog is local only and expires after a period (90 days by default for reachable entries) — it isn't a permanent backup

Example

git reflog
