select num in "${options[@]}"

                        find -name '*.sh' -print | wc -l
                        ;;
                "2- Get the total size of all the shell files from the current directory")
                        find -type f -name '*.sh' -exec du -ch {} + | grep total$
                        ;;
                "3- Get the total number of empty files in the system from the current directory")
                        find -size 0 | wc -l
