Combine the reflog flow to safely recover.
Safe recovery with reflog
Reflog helps you find previous HEAD positions after accidental resets or branch switches. First identify the correct commit with git reflog, then inspect its contents with git show. Protect the commit by creating a new branch so it does not become difficult to reach again.
git reflog
git show a1b2c3d
git branch recover a1b2c3dAfter protecting the commit, you can switch to the recovery branch and continue your work.
Practice Complete the recovery workflow
Use b7c8d9e as the example commit identifier. First point a new branch named safe to the commit, then inspect that branch's contents with git show, and finally switch to the branch. Complete the commands in the specified order.
