if [ -z "$1" ] ; then and if [ $# -lt 1 ]; then are basically the same.

I added the required extensions for you, hope you will like it. It's rather a quick & dirty hack than how it should be done in a professional manner. I mean it should be done using getopts.

Code:

#!/bin/bash

function usage {
echo
echo " Usage: `basename $0` [-d] directory [directory2] [directory3]"
echo
echo " Given a directory, this script estimates its file space usage,"
echo " separately counts files and directories in it."
echo
echo " -d        show subfolders of specified folder(s)"
echo " -h, --help    show this usage notice"
echo;exit
}

if [ -z "$1" ] ; then 
    usage
fi

case "$1" in
    -h|--help)    usage;;
    -d)        if [ -z "$2" ]; then
            usage
            fi
            shift
            dswitch=1;;
esac

for dirname in "$@"
do
if [ -d "$dirname" ]; then
 echo "CHECKING $dirname..."
 echo -n "SIZE: "
 du -s "$dirname"
 echo -n "FILES: "
 find "$dirname" -type f | wc -l
 echo -n "DIRECTORIES: "
 find "$dirname" -type d | wc -l

 if [[ $dswitch -eq 1 ]]; then
 find "$dirname" -type d
 fi
 echo
else
 echo "Directory \"$dirname\" does not exist!"
 echo
fi
done
