How to modify username and email in git

Modifying username and email in git is easy. When you make a git commit, the submitting username and email information are included with each submission. This information is used to track who submitted which code. Therefore, it is very important to modify this information in git. In this post, we will explore how to modify username and email in git.

Step One: Check Current Username and Email

First, let’s check the currently set git username and email.

To view the current git username, enter the following command in the terminal:

git config user.name

To view the current git email address, enter the following command in the terminal:

git config user.email

If no username or email is set, a blank screen will appear.

Step 2: Modify username and email

To modify the git username, enter the following command in the terminal:

git config --global user.name "your-username"

To modify the git email address, please enter Enter the following command in the terminal:

git config --global user.email "your-email-address"

Change "your-username" to the username you want to appear and "your-email-address" to your email address.

Please note that the "--global" option applies changes to all git repositories. If you only want to make changes to the current git repository, do not use the "--global" option.

Step Three: Check for Changes

To confirm that the changes were successfully applied, run the following command again:

git config user.name

git config user.email

This will output your new username and email address.

Step Four: Change Commit History

If you have used your old username and email address in previous commits, you will need to change your commit history. To do this, you need to use the git rebase command.

To use the git rebase command, first check out your git repository.

Next, enter the following command:

git rebase -i HEAD~n

"n" is a number that represents the number of commits you want to edit. This will open a list in the nano editor containing the commits you want to edit. Using the nano editor, replace "pick" with "edit" for the commit you want to change.

For example, if you wanted to change the first 5 commits, the command would look like this:

git rebase -i HEAD~5

Replace "pick" with "edit" for the first commit, then save the file and Close the nano editor.

Next, change the username and email address you want to change.

To change submissions, run the following command:

git commit --amend --author='Author Name <email@address.com>'

Change "Author Name" to your new username and "email@address.com" to your new email Email address.

Please note that the "--amend" option is used to change the previous commit, and you need to run this command on each commit you want to change.

After completing the changes, use the following command to perform a git rebase operation:

git rebase --continue

This will apply the changes and continue the rebase operation.

Once the operation is complete, you have now successfully modified your username and email address, and corrected your submission history.

Conclusion
