Final answer:
To revert a single commit in Git, use the git revert command followed by the commit hash.
Step-by-step explanation:
To revert a single commit in Git, you can use the git revert command followed by the commit hash of the commit you want to revert. This command creates a new commit which undoes the changes made in the specified commit. For example:
git revert abcdef1234567890
This will create a new commit that undoes the changes in the commit with the hash abcdef1234567890.
To revert a single commit in Git, you can use the `git revert` command. This command will create a new commit that undoes the changes made in the commit you specify. Here's the general process:
1. **Find the Commit Hash:**
- Use `git log` to find the hash of the commit you want to revert. Copy the commit hash.
2. **Revert the Commit:**
- Run the following command, replacing `commit_hash` with the actual commit hash you copied:
```bash
git revert commit_hash
```
For example:
```bash
git revert abcdef123
```
This will open a text editor to create a commit message for the new commit that undoes the changes. Save and close the editor.
3. **Complete the Revert:**
- After saving the commit message, Git will create a new commit that undoes the changes from the specified commit.
4. **Push the Changes (if needed):**
- If you're working in a shared repository and want to push the changes to the remote repository, use:
```bash
git push origin branch_name
```
Replace `branch_name` with the name of your branch.
This approach is safe because it creates a new commit that undoes the changes, preserving the history. If you want to remove the commit entirely and are certain that no one else has pulled the changes, you could use `git reset` or `git reset --hard`. However, these commands rewrite history and can cause issues for collaborators who have already pulled the changes.
Always be cautious when using commands that rewrite history, especially in shared repositories.
If you need to undo the last commit only (the most recent one), you can use `git revert HEAD` or `git revert HEAD~1`, where `HEAD~1` refers to the last commit.
