The git config --global user.name and git config --global user.email commands are used to set your Git identity globally on your system. This ensures that all commits made in any repository on your machine are associated with the correct author information. The user.name is the name that will appear in your commit history, and the user.email is the email address linked to your Git commits.

Optional Commands with `git config`

Here are some other useful configuration options that can be applied globally or locally:

Option	Description	Example
`git config --global user.name "<name>"`	Sets your Git username globally.	`git config --global user.name "Jane Doe"`
`git config --global user.email "<email>"`	Sets your Git email address globally.	`git config --global user.email "janedoe@example.com"`
`git config --global core.editor "<editor>"`	Sets the default text editor for Git.	`git config --global core.editor "vim"`
`git config --global color.ui true`	Enables colored output in Git commands to make the terminal output easier to read.	`git config --global color.ui true`
`git config --list`	Lists all current Git configuration settings.	`git config --list`

Syntax and Example

				
					# Set your Git username globally
git config --global user.name "Jane Doe"

# Set your Git email globally
git config --global user.email "janedoe@example.com"

# Verify your Git username
git config --global user.name
# Example output:
# Jane Doe

# Verify your Git email
git config --global user.email
# Example output:
# janedoe@example.com

# View all global configuration settings
git config --list
# Example output:
# user.name=Jane Doe
# user.email=janedoe@example.com
# color.ui=true

Why Use `git config --global user.name` and `git config --global user.email`?

Author Identification: These settings ensure that your commits are correctly attributed to you. They are important for collaboration, as others can see who made each change.
Global Configuration: By setting these options globally, you don’t need to specify your name and email for every repository. These values will apply to all repositories on your system unless overridden in a specific repository.
Consistency: Using the same name and email across repositories keeps your commit history consistent and professional, especially when using services like GitHub or GitLab.

Conclusion

The git config --global user.name and git config --global user.email commands are essential for setting your identity in Git. These settings ensure your commits are properly attributed to you, and applying them globally simplifies the configuration process across repositories. Configuring Git with your name and email is one of the first steps when setting up a new environment for version control.
