du -ah must be the reason since it is giving a varchar, numbers mixed with a letter, the "k". So nevermind and let's stop trying around; try this one:

Code:
#!/bin/sh

get_fsize()
{
    echo
    du -ak /data |\
    awk -v fs=$1 '$1 >= fs {print $0}'
}

echo "Enter the minimum filesize to be displayed:"
read FSIZE

case ${FSIZE} in
    [0-9]*)     get_fsize ${FSIZE};;
         *)     echo "Invalid input."
                exit 1
                ;;
esac

echo -e "\nDone."

exit 0
