Try a quick fix!
if you MUST have "-a xx AND -b zz" on the command line then add this to your code.....
if [ $# != 4 ]
then
echo "Usage; `basename $0` -a value -b value'
exit 9
fi
while getopts "a
" opt 2>/dev/null
do
case "${opt}" in
a) echo "A:${OPTARG}" ;;
b) echo "B:${OPTARG}" ;;
*) exit 1 ;;
esac
done
> getopts.sh -a TEST1 -b TEST2
A:TEST1
B:TEST2
> getopts.sh -a -b TEST2
Usage; getopts.sh -a value -b value
