How to Change the Commit Author for a Specific Commit
Changing the author of a specific commit in Git can be necessary in certain situations, such as when you made a commit with incorrect author information or when you need to update the author for a historical commit. This article will guide you through the process of changing the commit author for a specific commit in Git.
Identify the Commit
The first step is to identify the commit that you want to modify. You can do this by determining the commit hash or the position of the commit in the commit history. This will help you locate the specific commit that needs to be modified.
Perform an Interactive Rebase
Once you have identified the commit, you can perform an interactive rebase to modify it. Use the “git rebase -i” command followed by the commit hash or the position of the commit that comes before the one you want to modify. This will open a text editor with a list of commits.
Edit the Commit
In the text editor, locate the commit that you want to modify and replace the word “pick” with “edit” on the same line. Save and close the text editor.
Amend the Commit
Git will stop at the commit you want to modify. Use the “git commit –amend” command to make the necessary changes to the commit, such as updating the author’s name, email, message, or signature. Save and close the text editor.
Complete the Rebase
After amending the commit, use the “git rebase –continue” command to continue the rebase process and apply any remaining commits.
Push the Changes
If you have already pushed the commit to a remote repository, you may need to force push the changes using the “git push –force” command. However, be cautious when force pushing, as it can overwrite other people’s work. Consider the implications and consult with your team before proceeding with a force push.
It’s important to note that changing the author of a commit effectively rewrites commit history. This can have implications for your collaborators, especially if they have based new work on the original commits. Therefore, exercise caution and consider the impact before rewriting commit history.

How do I identify the specific commit that I want to modify?
To identify the commit, you can determine the commit hash or the position of the commit in the commit history. This will help you locate the specific commit that needs to be modified.
What is an interactive rebase and how does it help in changing the commit author?
An interactive rebase is a Git command used to modify commits interactively. By using the “git rebase -i” command followed by the commit hash or position of the commit before the one you want to modify, you can open a text editor with a list of commits. This allows you to make changes to the commit, including the author.
How can I edit the commit author in the interactive rebase text editor?
In the text editor opened by the interactive rebase command, locate the commit you want to modify and replace the word “pick” with “edit” on the same line. This signals to Git that you want to modify that specific commit.
What command should I use to amend the commit and change the author’s information?
After making the necessary changes to the commit in the text editor, save and close the editor. Then, use the “git commit –amend” command to amend the commit and make the desired changes to the author’s name, email, message, or signature.
How do I complete the rebase process after amending the commit?
After amending the commit, you can use the “git rebase –continue” command to continue the rebase process. This will apply any remaining commits and finalize the modifications you made to the specific commit.
Do I need to force push the changes if the commit has already been pushed to a remote repository?
If you have already pushed the commit to a remote repository, you may need to force push the changes using the “git push –force” command. However, be cautious when force pushing, as it can overwrite other people’s work. Consider the implications and consult with your team before proceeding with a force push.
What are the implications of changing the author of a commit?
Changing the author of a commit effectively rewrites commit history. This can have implications for your collaborators, especially if they have based new work on the original commits. Therefore, exercise caution and consider the impact before rewriting commit history.
Are there any limitations or considerations when changing the commit author?
When changing the commit author, it’s important to note that the new author information will only apply to future commits, not past ones. Additionally, modifying commit history can introduce complexities and conflicts, so it’s crucial to communicate with your team and consider the implications before making any changes.
