Blocking command line pushes that expose your personal email address
If you've chosen to keep your email address private when performing web-based operations, you can also choose to block command line pushes that may expose your personal email address.
When you push commits from the command line, the email address that you've set in Git is associated with your commits. This setting blocks you from pushing commits on the command line that use your personal email address.
For more information on commit email addresses, including your GitHub-provided
noreply email address, see "Setting your commit email address."
