You do everything you need within sh. Someone else pointed out
that case/esac is your friend here. It was not quite complete. Here's
more complete example that will let you pair up the options and their
arguments if they take them.
ifconfig_args="media 10baseTX dhcp mediaopt half-duplex"
set -- ${ifconfig_args}
while [ $# -gt 0 ]; do
op=$1
case ${op} in
[Mm][Ee][Dd][Ii][Aa])
op_arg=$2
shift
echo "op=media op_arg=${op_arg}"
;;
[Mm][Ee][Dd][Ii][Aa][Oo][Pp][Tt])
op_arg=$2
shift
echo "op=mediaopt op_arg=${op_arg}"
;;
[Dd][Hh][Cc][Pp])
echo "do something dhcp specific..."
;;
*)
echo "unknown op: ${op}"
;;
esac
shift
done
