Episode 86 — Recovery skills: reset vs stash, tags, safe undo thinking

Linux+ includes Git recovery skills because real operations involves mistakes, urgent reversals, and the need to return to a known-good state without making the situation worse. This episode explains reset versus stash as two different recovery tools: reset changes where your branch points and can rewrite local history, while stash temporarily saves uncommitted changes so you can switch context cleanly. You’ll learn why tags matter as lightweight anchors to known-good versions, especially when you need to reference or return to a specific release or configuration baseline. The exam often tests whether you understand “undo” as a spectrum—uncommitted changes, staged changes, committed changes, and pushed changes—and whether you choose an action that matches the scope and risk of the situation.

we apply safe undo thinking to practical scenarios. You’ll practice deciding how to recover when you edited the wrong file, staged the wrong changes, or need to hotfix production while preserving work in progress. We also cover common pitfalls: using destructive resets on shared history, stashing without documenting what you stashed, and losing track of which commit represents the deployed baseline. Finally, you’ll learn best practices aligned with exam intent: treat rollback as a controlled change, use tags or documented commit references for releases, verify your working tree state before and after recovery actions, and test the restored configuration so “undo” restores functionality, not just a comforting Git status output.
