You can change your name and email for your global Git configuration using the following commands in your terminal:

git config --global user.name "Your Name"
git config --global user.email "your.email@example.com"

Of course, you will want to replace "Your Name" with your desired name and "your.email@example.com" with your desired email address. This will update your global Git configuration, and these details will be used for all your commits.

If you want to verify the changes, you can use:

git config --global --list

This command will list all your global Git configuration settings, including your updated name and email.
