Locate Git submodule config file
Git submodules don’t put their individual Git config file under .git/config. This Git command issued from the Git submodule directory tells the file path to the Git submodule config file:
git rev-parse --git-path config
Say a repository “alpha” has submodule “beta”. Find the Git config file location of “beta” from “alpha” like:
git -C beta rev-parse --git-path config
# OR
cd beta
git rev-parse --git-path config
