Add a list of submodules to the git

I have cloned a project and customized it. the project is using some extra projects as submodules. I have setup mine git repository and push the main project there. but I did not add the submodules to mine git project.

I want to pull the submodules to my project. I know using following command I can add submodules one by one :

git submodule add <sub-m url> <path>

But they are a lot. is there another way to add them automatically and all together ? here is the list of submodules :

submodule "submodules/bcg729"]
    url = git://git.linphone.org/bcg729.git
[submodule "submodules/bctoolbox"]
    url = git://git.linphone.org/bctoolbox.git

I don't think there is such a way with git. However, you could just do a shell script that iterates your list and calls git submodule add on each of them, one by one.

---

Why just copying them to .gitmodules or to .git/index won't do the trick:

The "git submodule add" command does a couple of things:

It clones the submodule under the current directory and by default checks out the master branch.

It adds the submodule's clone path to the ".gitmodules" file and adds this file to the index, ready to be committed.

It adds the submodule's current commit ID to the index, ready to be committed.

(source)

So you would be missing the last step, and git submodule init/update expect the commit id to be already in place. That is why you need git submodule add .

---

Based on @eis suggestion, you have to create a script to make all the git add commands.

A way to do that is to create the .gitmodules containing your needs, then parse it with a script like this one:

iterator=1;
subpaths=$(git config --file .gitmodules --get-regexp path | awk '{ print $2}');
subrepos=$(git config --file .gitmodules --get-regexp url | awk '{ print $2}');
for path in $subpaths; do
  repo=$(echo "$subrepos"| sed $iterator'q;d');
  git submodule add $repo $path;
  let iterator++;
done
