git-submodule: Install a repository's specified submodules.

$ git submodule update --init --recursive

try on your machine

The command git submodule update --init --recursive is used to initialize, update, and recursively update submodules within a git repository.

Here's a breakdown of what each flag does:

--init: This flag is used to initialize any submodules that have been added to the repository but haven't been initialized yet. Initialization involves cloning the submodule repositories into the specified directories.
--recursive: This flag is used to recursively update submodules and any nested submodules within them. It initializes and updates all submodules, including their submodules and so on.
update: This command is used to update the submodules. It fetches the latest changes from the remote submodule repositories and integrates them into the main repository.

So, when you run git submodule update --init --recursive, it ensures that all the submodules within your repository are properly initialized, and recursively updates them to the latest commit in their respective repositories, including nested submodules as well.
