Undo a Commit Safely (Without Losing Work)

Git & GitHub

Technical Specification

Practice undoing last commit using git reset --soft, and git revert for already pushed commits.

Input/Output Samples

Input:bad commit pushed

Output:use git revert <hash>

Optimal Logic Path

# undo last local commit, keep changes staged
git reset --soft HEAD~1

# revert a specific commit safely
git revert <bad-commit-hash>

Architectural Deep-Dive

Choosing correct undo method depends on whether commit is already shared with others or not.
