浅析shell脚本如何调用getopts读取-h和-v等参数

while getopts hva: op; do
    case $op in
        h)
            echo 'luther.gliethttp test'
        ;;

        v)
            echo 'v1.0-2008.12.27'
        ;;

        a)
            echo "args=$OPTARG"
        ;;
    esac
done

shift `expr $OPTIND - 1`
echo $@

./run.sh -h -v -a 12,5,luther.gliethttp 1 2 3 4 5
luther.gliethttp test
v1.0-2008.12.27
args=12,5,luther.gliethttp
1 2 3 4 5
其中getopts,$OPTARG和$OPTIND都是系统内置函数和变量
