shell 的getopt 指令之迷之错误?

Question

目前给脚本写了一个getopt 加入了以下参数

usage() {
    cat <<-EOF
    Usage: sh|bash $sh_name -[option]
    
    sh  $sh_name -e | --env-set                       (Manually set hcs environment variables with higher priority than setting.conf, example: -e DB_HOST=10.77.0.28 or --env-set REDIS_HOST=10.770.029)
    sh  $sh_name -t | --timeout-periods               (Set the timeout of the script, if not set the default value is 120 seconds, you can set the time interval in seconds, minutes, hours, days, for example, ten days is set to 10d, three hours is set to 3h and so on and so forth)
    sh  $sh_name -T | --test-mode                     (Start debug mode, this stage will not actually execute the installation script, but will print some process parameters)
    sh  $sh_name -s | --skip-mode                     (This mode will skip some health checks such as checking ip and network card name, disk space, etc.)
    sh  $sh_name -S | --secure-mode                   (Manually enter some private configuration such as mysql password, redis password, etc.)
    sh  $sh_name -r | --relaxed-mode                  (Loose mode : no assignment command will be executed: the hcs installation media will be manually assigned, and the alias function of docker-compose will not be generated in /etc/profile)
    sh  $sh_name -v | --version                       (Print hcs version information)
    sh  $sh_name -h | --help                          (usages for help)
EOF
}

假设脚本为 billity.sh

目前执行 一下指令皆无报错

sh billity.sh -e key=value
sh billity.sh -h
sh billity.sh -T
sh billity.sh -t
sh billity.sh -t100s

如果有多个指令就报错 譬如

sh billity.sh -T -e key=value

如果把两个参数放在一起 又可以了

sh billity.sh -Te key=value

而且此时 -e 如果有多个参数 要写成

-e key1 key2 key3这种形式

而不是我想要的 -e key1 -e key2 -e key3

下面贴一下脚本

usage() {
    cat <<-EOF
    Usage: sh|bash $sh_name -[option]
    
    sh  $sh_name -e | --env-set                       (Manually set hcs environment variables with higher priority than setting.conf, example: -e DB_HOST=10.77.0.28 or --env-set REDIS_HOST=10.770.029)
    sh  $sh_name -t | --timeout-periods               (Set the timeout of the script, if not set the default value is 120 seconds, you can set the time interval in seconds, minutes, hours, days, for example, ten days is set to 10d, three hours is set to 3h and so on and so forth)
    sh  $sh_name -T | --test-mode                     (Start debug mode, this stage will not actually execute the installation script, but will print some process parameters)
    sh  $sh_name -s | --skip-mode                     (This mode will skip some health checks such as checking ip and network card name, disk space, etc.)
    sh  $sh_name -S | --secure-mode                   (Manually enter some private configuration such as mysql password, redis password, etc.)

    sh  $sh_name -h | --help                          (usages for help)

求大佬指点 谢谢

好吧 已经找到解决方案了 原因就是

在主脚本里面设置了param 但是没有把他识别为数组导致的

declare -a param=($@)

即可
