In this quick tip, we’ll see how to configure Git to use a global .gitignore file.
Git allows you to use a global .gitignore for all your repositories. Let’s see how.
First, create a ~/.gitignore in your home folderand anything that should be ignored when pushing your code.
Next, instruct Git to use the file using the following command:
$ git config --global core.excludesfile ~/.gitignore
That’s, you can now use the global ~/.gitignore file to exclude files across all your projects, but you can also use a .gitignore file inside your project and both will be used by Git.
