file=$1
directories=0
files=0
rfiles=0
xfiles=0
wfiles=0

if [ $# -ne  1 ]
   then
        echo "Usage: assignment4.sh <directory_name>"
exit
fi


if [ ! -d $file ]
then
        echo "$file: is not a directory"
exit
fi
        

for filename in $file/*
     do
        if [ -r $filename ];
            then 
             rfiles = `expr $rfiles + 1`   
        fi

        if [ -x $filename ]
           then
                xfiles = `expr $xfiles + 1`
        fi
 if [ -w $filename ] 
           then  
                wfiles = `expr $wfiles + 1`
        fi

        if [ -d $filename ]
           then
                directories = `expr $directories + 1`
        fi
        if [ -f $filename ] 
           then

echo "Total number of files: $files"
echo "Total number of readable items: $rfiles"
echo "Total number of writable items: $wfiles"
echo "Total number of executable items: $xfiles"

Start by removing spaces from both sides of =

i.e.
Code:
X = `blah`

Becomes
Code:
X=`blah`

Shell is picky about spacing! X=1 means 'assign "1"to X'. X = 1 means 'run something called "X" with arguments "=" and "1"'.
