How to delete git submodule • Tuan Tran

My blog use hugo framework, and install theme by using git submodule.

Each time I change my theme, I want to completely remove submodule of old themes.

Solution

Open .gitmodules files, remove relevant section.
Stage the .gitmodules changes: git add .gitmodules
Open .git/config, remote relevant section.
Run git rm --cached path_to_submodule
Run rm -rf .git/modules/path_to_submodule
Commit git commit -m "Removed submodule"
Delete the submodule: rm -rf path_to_submodule
