Using --getopts to pick up whole word flags

Question

Can getopts be used to pick up whole-word flags?

Something as follows:

while getopts ":abc --word" opt; do
    case ${opt} in
        a) SOMETHING
            ;;
        ...
        --word) echo "Do something else."
            ;;
    esac
done

Trying to pick up those double-dash flags.

Found one way to do this:

while getopts ":abc-:" opt; do
    case ${opt} in
        a) echo "Do something"
            ;;
        ...
        -)
            case ${OPTARG} in
                "word"*) echo "This works"
                    ;;
            esac
    esac
done

By adding -: to the opstring and adding a sub-case using $OPTARG, you can pick up the long option you want. If you want to include an argument for that option, you can add * or =* to the case and pick up the argument.
