Viewing Git Configuration

Quick-start

All operations need to be done in the myrepo directory, so the first thing you should do is run the cd ~/project/myrepo command to get into the working directory.

cd ~/project/myrepo

To view your current Git configuration, you can use the git config --list command. This command will display all the configuration settings that are currently set in your Git environment. Git configuration is hierarchical, with settings in your user configuration file taking precedence over settings in your global configuration file, which in turn take precedence over system configuration files.

git config --list

This command will output something like this:

user.name=John Doe
user.email=johndoe@example.com
color.ui=auto

You can also view specific configuration values by specifying the key, like this:

git config user.name

This command will output the value of the user.name configuration variable.

Setting the Username and Email Address

It's important to set your username and email address in Git because it is used for authorship when you make commits. To set your username and email address, you can use the git config command with the --global option.

git config --global user.name "labex"
git config --global user.email labex@example.com

You can also set these values on a per-repository basis by omitting the --global option and running the command within a specific repository. This will override the global values for that repository.

git config user.name "Jane Smith"
git config user.email janesmith@example.com

Modifying Git Configuration

You can modify your Git configuration by using the git config command with the appropriate options. For example, to change the value of the color.ui setting to true, you can use the following command:

git config --global color.ui true

To remove a configuration setting, you can use the --unset option. For example, to remove the color.ui setting, you can use the following command:

git config --global --unset color.ui

You can also edit the configuration files directly by hand. The global configuration file is located at ~/.gitconfig on Unix-like systems, and C:\Users\YourUserName\.gitconfig on Windows. The local repository configuration file is located at .git/config in the root of your repository.

Summary

In this lab, you learned how to use git config command to manage your Git configuration. Specifically, you learned how to view your configuration, set your username and email address, and modify your configuration. Remember that your Git configuration is important for authorship and personalization, so it's important to keep it up-to-date. By the end of this lab, you should be comfortable using git config commands to manage your Git configuration.
