A systems administrator installed Git on a new workstation and wants to ensure all Git projects on this machine are initialized with the same username and email address. Which of the following…

The `git config --global user.name = "James Doe"` command sets the user's name globally across all Git repositories on the machine, ensuring that every commit from this workstation will use "James Doe" as the author name unless overridden locally. The `--global` flag writes to the `~/.gitconfig` file.

Directly appending to `.git/.gitconfig` is incorrect because the global configuration file is typically `~/.gitconfig`, not `.git/.gitconfig`, and direct file manipulation is not the standard way to configure Git.

Directly appending to `.git/.gitconfig` is incorrect for the same reasons as choice B; the global configuration file is `~/.gitconfig` and direct manipulation is not the standard approach.

The `git config username = "James Doe"` command is missing the `user.` prefix for the configuration variable and the `--global` flag, so it would not correctly set the global username.

The `git config --global user.email = "[email protected]"` command sets the user's email address globally for all Git repositories on the machine, ensuring that "[email protected]" is used for all commits from this workstation unless a local override exists. The `--global` flag writes to the `~/.gitconfig` file.

The `git config email.addr = [email protected]"` command is missing the `user.` prefix for the configuration variable and the `--global` flag, and also has a syntax error with the unclosed quote, so it would not correctly set the global email.
