Git Version Rollback: A Secure Method to Recover Code from Erroneous Commits

In Git version control, if incorrect code is committed, you can revert to a previous version to recover. First, use `git log --oneline` to view the commit history and obtain the target version's hash value. The core methods for reverting are divided into three scenarios: 1. **Undo the most recent incorrect commit**: Use `git reset --soft HEAD~1`. This only reverts the commit record while preserving changes in the staging area and working directory, allowing re - submission. 2. **Revert to a specific version**: Use `git reset --hard <target - hash - value>`. This completely reverts the version and discards subsequent modifications (ensure no important unsaved content exists before operation). 3. **Revert errors that have been pushed to the remote**: First, revert locally, then use `git push -f` to force - push. This requires confirming there is no collaboration among the team. For collaborative work, the `revert` command is recommended. **Notes**: Distinguish between `--soft` (preserves modifications), `--hard` (discards modifications), and `--mixed` (default). For uncommitted modifications, use `git stash` to temporarily store and then recover them. Forcing a push to the remote is risky and should be avoided in branches with multiple team members collaborating. The key is to confirm the version, select the correct parameters, and operate remotely cautiously to safely revert from errors.
