Proper Way to Remove a Git Submodule

submodules.sh

# A lot of times people have trouble removing Git submodules, receiving errors about the index still existing in their repo even after 
# they deleted the module directory. This is the correct way to do it.

# Add a submodule just so we can remove it
git submodule add https://github.com/Nickersoft/push.js.git ./data/push

# Remove the submodule from the Git cache
git rm --cached ./data/push

# Remove Git module files
rm -rf .git/modules/data/push

# Remove either .gitmodules if it's your only submodule, or remove the block that looks like this from that file:
# [submodule "data/push"]
# 	path = data/push
# 	url = https://github.com/Nickersoft/push.js.git
rm -rf .gitmodules

# Finally, you can remove the actual module directory
rm -rf ./data/push
