Some git submodule related operations?

--> Describe the problem

There is one situation we often encounter: one working project needs to include and use another. Git addresses this problem through submodule which allows you to use another Git repository as a subdirectory. Some operations related to the GIT submodule are shown below.

--> Demonstrate the solution

• Add a new submodule in the local git repository:

  git submodule add <remote_sub_repo_url> <local_dir_name>

• Load the submodule in two ways:

  # way 1: recursively clone the entire project(include it's subrepository)
  git clone --recursive <remote_repo_url>
  # way 2: initialize the submodule and update it after normal clone
  git submodule update --init --recursive

• Delete the submodule in the local git repository:

  git rm -f <submodule_dir_name>
  rm -rf .git/modules/<submodule_name>
