Pushing all submodules recursively

Question

I wrote the below script to push all the changes in the workspace, both in the submodules and the superproject. However, it sounds a little odd that, it is this complex to do wh

Answer 1

This c# console app prompts you for each submodule with changes and allows you to easily add/commit/push or run custom git commands:
