If you’re working with Git, you might find that there are files specific to your system that you’d prefer Git to ignore across all your repositories. Rather than creating a .gitignore file for every project, you can set up a global .gitignore file. This quick guide will show you how to configure and apply it.
What is a Global .gitignore File?
A global .gitignore file allows you to specify files and directories that Git should ignore across all your projects, ensuring you don’t accidentally commit files like system-specific cache or config files.
Steps to Set Up and Apply a Global .gitignore File:
1. Create a Global .gitignore File
First, you need to create a global .gitignore file. Open your terminal and create the file with this command:
touch ~/.gitignore_global
You can now open this file in your favorite text editor and add the files or patterns you want Git to ignore globally. For example, to ignore macOS system files, you might add:
# macOS system files
.DS_Store
2. Configure Git to Use the Global .gitignore File
After creating the file, you need to tell Git to use it as your global ignore file. Run the following command in your terminal:
git config --global core.excludesfile ~/.gitignore_global
This command instructs Git to reference your newly created .gitignore_global file for all repositories on your machine.
3. Verify the Configuration
To confirm that Git is using your global .gitignore file, you can run:
git config --global core.excludesfile
Conclusion:
By setting up a global .gitignore file, you save time and effort when managing multiple projects, ensuring that unwanted files are consistently ignored across all your repositories. This is particularly helpful on macOS, where certain system files (like .DS_Store) can clutter up your Git repositories.
Now that you’ve set it up, you can focus on coding without worrying about accidentally committing unnecessary files.
