Git add submodules to super project from existing repos

Question

I have several (about 10-15) Git repositories in a directory:

~/plugins/admin
~/plugins/editor
~/plugins/etc

Each have their own separate repository and remote server.

The problem is that to pull all the changes from all the repositories I have to:

cd ~/plugins/admin
git pull origin master
password: ********
cd ..

cd ~/plugins/editor
git pull origin master
password: ********
cd ..

cd ~/plugins/etc
git pull origin master
password: ********
cd ..

How can I setup either Git submodules to pull all the repositories with 1 command,

OR alternatively write a script for Windows, Linux and Mac (as I use all 3 operating systems) to effectively do the same thing. Keeping in mind that the repos can be on different branches and don't necessarily have a tracking branch setup.

Same notes:

• The password is the same for all repos
• The remote server is the same repos (obviously in seperate repos/directories)
• I only want to type the password in once
• I only want to type one command to pull all repos
• Public/private keys are not an option
• I'm connecting to the remote via ssh

Answer 1

bash-3.2$ git submodule add git@repoUrl:SubmoduleName.git existing/submodule/path
Adding existing repo at 'existing/submodule/path' to the index

when you're trying to add submodule from place where some git repo already exists this repo will be added in index.
