Day 3/30 - Undo Git Mistakes: The Ultimate git reflog Guide
- Git's reflog is a powerful feature that acts as a safety net by recording all reference changes locally.
- It can be used to recover from accidental deletions, lost branches, bad rebases, and hard resets.
- Reflog tracks the movement of the HEAD pointer, branch reference updates, and all Git actions.
- Commands like git reflog, git reflog show branch-name, and git reflog -n 10 are common ways to interact with reflog.
- Real-world recovery scenarios include recovering lost commits, undoing bad rebases, finding lost work after hard reset, and recovering deleted branches.
- Pro tips include time-based references, configuring reflog expiration, combining with bisect, detailed reflog view, creating safety nets, using colorful reflog alias, and undoing the last move.
- An alias can be used to recover lost stashes by finding stash operations in reflog and applying a specific stash.
- Checking reflog immediately when issues occur, looking for the last known good state, using HEAD@{n} references or commit hashes to recover, and creating aliases are recommended practices.
- Git reflog is a valuable tool for Git users to undo mistakes and recover lost work effectively.
- The article also provides detailed examples of using reflog in various recovery scenarios and offers pro tips for better utilization.
