while getopts htn: OPTION
do
        case ${OPTION} in
                t)  LIST='john mike smith' ;;
               n) LIST='rob peter joe' ;;
               h|*)  show_usage
                     exit 0
                     ;;
        esac
done
shift $(($OPTIND - 1))
args=$*

above is a snippet of code. i would like to use more than one character in my options e.g fname lname should count as 2 options instead of "while getopts htn: OPTION"
would like something like "while getopts fname lname: OPTION
How do i get getopts to work in that form.

I don't think getopts knows how to parse words as options (and not as non-GNU-style, certainly). You are probably better off writing your own parser, something like this:

        case ${1:1} in
