}

echo -e "\n------ Validating all YAML files (may takes several minutes) ------"

# If there are no YAML file, simply exit

ls | grep -q yaml

found_yaml=$?

if [ ! $found_yaml ] ; then

    echo "-- No YAML files."

# If there are no YAML files nor JSON files, simply exit

if ! ls | grep -Eq '\.ya?ml$|\.json$'; then

    echo "-- No YAML or JSON files."

    exit 0
