sh

# Search directories with name node_modules
find . -name 'node_modules' -type d
# Displays parent folders and child folders

./hapi/hapi-auth-jwt2/node_modules/optimist/node_modules (child)

# we want to delete parent folders anyway so no need to search inside those for child results
# Add '-prune' flag
find . -name 'node_modules' -type d -prune
# Displays parent folders only
./laravel/passport/node_modules
./hapi/hapi-auth-jwt2/node_modules

# Delete find results
# The {} gets replaced with the find result
find . -name 'node_modules' -type d -prune -exec rm -r {} \;
