How effectively delete a git submodule.

delete_git_submodule.md

To remove a submodule you need to:

• Delete the relevant section from the .gitmodules file.
• Stage the .gitmodules changes git add .gitmodules
• Delete the relevant section from .git/config.
• Run git rm --cached path_to_submodule (no trailing slash).
• Run rm -rf .git/modules/path_to_submodule (no trailing slash).
• Commit git commit -m "Removed submodule "
• Delete the now untracked submodule files rm -rf path_to_submodule

This seems to be a more modern version (copied from https://stackoverflow.com/a/36593218/2066118):

# Remove the submodule entry from .git/config
git submodule deinit -f path/to/submodule

# Remove the submodule directory from the superproject's .git/modules directory
rm -rf .git/modules/path/to/submodule

# Remove the entry in .gitmodules and remove the submodule directory located at path/to/submodule
git rm -f path/to/submodule

For those of us on Windows, here's the equivalent in Powershell:

# Remove the submodule entry from .git/config
git submodule deinit -f path\to\submodule

# Remove the submodule directory from the superproject's .git/modules directory
rm .git\modules\path\to\submodule -r -fo

# Remove the entry in .gitmodules and remove the submodule directory located at path/to/submodule
git rm -f path\to\submodule

Thank You So much guys!
