Try looking up zparseopts. It is along the same lines as bush's getopts.

I'm sure there has to be a better way of doing this=2C but the way that I'v=
e done it has always worked for me=2C so I've never bothered to look furthe=
r.

Here's what I do:


    ANOTHER=3Dno
    SOMETHING=3Dno

    for ARGS in "$@"
    do
        case "$ARGS" in
            -s|--something)
                    SOMETHING=3Dyes
                    shift
            =3B=3B

            -a|--another)
                    ANOTHER=3Dyes
                    shift
            =3B=3B

            -*|--*)
                    echo "  $NAME [warning]: Don't know what to do with arg=
: $1"
                    shift
            =3B=3B

        esac

    done # for args

The only downside to this is that you can't combine arguments such as `-sa`=
 you have to use `-s -a`

Am I right? Is there a better way?

ps - I'm not _overly_ concerned with "portability" to other shells. I write=
 zsh scripts because I like what zsh has to offer.
