Learn submodule sync with git submodule update.
git submodule update
When you clone a parent repository, submodule directories may initially be empty. Use git submodule update to fetch the recorded submodule commits and prepare their working directories. Add the --init option when the submodule configuration needs to be initialized first.
git submodule update --initThis operation uses the submodule commit references recorded by the parent repository.
Recursive updates
A submodule can itself contain other submodules. In such nested structures, updating only the top level may not be enough. The --recursive option includes submodules inside other submodules in the operation.
git submodule update --init --recursiveThis command initializes the required submodule configurations and checks out recorded commits for nested submodules as well.
Practice Initialize and update submodules
Initialize all submodules in the project and check out their recorded commits, including nested submodules.
