add something with awk or sed
Hi experts

I have lots of test.sh, each test.sh has the dotest1() function, I want to add below code before dotest1() if the runtest.sh don't contains "getopts", can someone show me the way
Code:
while getopts "s" arg 
do
        case $arg in
             s)
                echo "ss"
                ;;
             ?) 
            	echo "unkonw argument"
        exit 1
        ;;
        esac
done

Is runtest.sh the same as the beforementioned test.sh, and is the position of getopts related to dotest1() or will it occur anywhere in the script?
