Whether you're maintaining a library or just using one, understanding how to manage submodules effectively can be valuable in your Git toolkit. By specifying branches, tags, or commits, you can have fine-grained control over the versions of these submodules. As explained above, a submodule is a link that points to a specific commit in the child repository. If -recursive is specified, this command will. git branch -recurse-submodules topic origin/main will create the submodule branch 'topic' that points to the submodule commit in the. git submodule sync synchronizes all submodules while git submodule sync - A synchronizes submodule A only. Submodule operations can be configured using the following mechanisms (from highest to lowest precedence): The command line for those commands that support taking submodules as part of their pathspecs.
