Shell script to display file permissions

Script:
#displays a list a list of files in directory via arguments read,write& execute
#echo Enter the directory name :
read dir
if [ -d $dir ]
    then
        cd $dir
        ls>f
        exec<f
        while read line
            do
                if [ -f $line ]
                    then
                        if [ -r $line ] && [ -w $line ] && [ -x $line ];
                            then
                                echo $line has all permissions
                        else
                            echo $line has not all permissions
                        fi
                fi
            done
fi

Output:
