Update all the submodule files

You can use submodule to manage different project file on git. But the subodule might include another submodule. So you can run the following command to fetch all the files from submodule’s submodule.

git submodule update --init --recursive

Submodule hint

Because the submodule might have its own submodule. So the submodule might cause the recursive submodule problem to the infinite loop from fetching all the submodule files.

So the better way is to make a rule to include submodule to prevent the recursive submodule problem.
