need help in question !!!

[leo7_24]

Write a Bash shell script that receives only one argument via command line. (Ensure that the argument must be exactly one and it must be a directory which is owned by you. If not the script exits). The script should display the number of readable, writable and executable files in that directory.

For the question written above please recommend me any solution .... i have written a code but its not giving me valid output .. u can also see my code below :

#!/bin/bash

read=0
write=0
exec=0

if [ $# -eq 1 -a -d "$1" ]
then

ls $1 > perm
for var in $( cat perm )
do

if [ -r "$var" ]
then

read=`expr $read + 1`

fi
done
else
echo "Error"

this is just for checking the readable ..... rest of other are like the same ....
