Question

A network automation engineer checks out a specific commit hash to test an experimental Jinja2 template change: 'git checkout a1b2c3d'. Git warns they are in a 'detached HEAD' state. The engineer makes two commits with the fixed template and validates the config generation successfully. Before returning to work, they run 'git checkout main'. The next day they realize the two commits are gone from the log and want to preserve that work properly. What is the correct sequence to recover and preserve the commits?

Accepted Answer

Use 'git reflog' to find the lost commit hash, then create a branch from it with 'git branch recovery <hash>', and merge that branch into main.

Answer

Run 'git checkout main' again followed by 'git pull' to force the remote to restore the missing commits into the working branch.

Answer

Run 'git fsck --lost-found' and then 'git reset --hard main' to reattach the dangling commits to the current branch.

Answer

Use 'git stash pop' to recover the detached HEAD commits, since detached commits are automatically stored in the stash on checkout.
