Shell Programming and Scripting

hi guys i want a script manually copy all directories and files. Dont want to use cp-r, cp-R or any variant. How to do this, the piece of code i need is commented in the script

Code:

#!bin/bash

IFS=$'\n'

if test "$1" = ""
then
        wd=pwd
else
        wd=$1
fi

for file in $(find $1)
do
        if [ -f $file ]; then
                cp $file ~/Desktop
        elif [ -d $file ]; then
                 #copy directory,subdirectory and files wihtout
                 #using cp-r, cp-R or any variant
        fi
done

thanks in advance

Something like, when a directory is found elif [ -d file ]; then

look in that directory if it contains more files or folders
create or copy folder and also containing files and folders
