这可能吗？

下面：

#!/bin/bash

OPTS=`getopt -o axby -l long-key: -- "$@"`
if [ $? != 0 ]
then
    exit 1
fi

eval set -- "$OPTS"

while true ; do
    case "$1" in
        -a) echo "Got a"; shift;;
        -b) echo "Got b"; shift;;
        -x) echo "Got x"; shift;;
        -y) echo "Got y"; shift;;
        --long-key) echo "Got long-key, arg: $2"; shift 2;;
        --) shift; break;;
    esac
done
echo "Args:"
for arg
do
    echo $arg
done

$ foo的-ax --long键val的输出-b -y某些文件名：

Got a
Got x
Got long-key, arg: val
Got b
Got y
Args:
SOME
FILE
NAMES
