Where is the Git config file located?

Last updated: January 27, 2024

Introduction

Git, the distributed version control system, is integral to modern software development. Understanding Git’s configuration files is vital for customizing the Git experience to suit individual or team needs. This tutorial will guide you through finding and understanding the Git config files, from the basic concepts to advanced configurations.

Understanding Git Configuration Levels

Git utilizes three levels of config files: system, global, and local. The system-level config applies to every user on the system and all their repositories. The global-level config is user-specific and pertains to all the repositories that user accesses. Lastly, the local-level config is repository-specific.

$ git config --list --show-origin

The above command lists all the configurations and thier origins to give you a clear understanding of what config is set where.

Locating System-Level Git Config

The system-level Git config file is usually located in the etc directory on the system. It is applicable to all the users. You can view the system configurations using this command:

$ git config --system --list

To locate the system gitconfig file directly:

$ git config --system --get-regexp '' \ # Fetch all entries
co=core.editor /bin/nano            # Output example

Finding Global-Level Git Config

The global Git config is specific to your user profile on the system. It might vary across operating systems:

# For Unix-like systems including macOS:
$ cat ~/.gitconfig

# For Windows systems:
$ type %USERPROFILE%\.gitconfig

To open the global config file directly with the default editor, you can use:

$ git config --global --edit

Accessing Local-Level Git Config

The local-level config is specific to a repository and can override global settings. It can be found in the .git directory of your repository:

$ cat path/to/your/repo/.git/config

Edit local config with Git command:

$ git config --local --edit

Advanced Git Configuration

Beyond merely finding the config files, you may want to ensure configurations work as expected.

Listing Config with Precedence

To list all configuration values with their respective precedence from local to global to system:

$ git config --list --show-origin --show-scope

Editing Configurations

Modify a setting (for example, setting the core editor) at the global level:

$ git config --global core.editor vim

Conditional Includes

Advanced users can define conditional includes for configs:

[includeIf "gitdir:~/work/"]
    path = .gitconfig-work

This snippet tells Git to use an additional config file when you’re working in the ‘~/work/’ directory.

Conclusion

The Git configuration system’s flexibility allows for personalized settings across various scopes. By understanding where these config files are located and how they function within Git’s hierarchical structure, you can better control your development environment and workflow.
