getopt不接受以连字符开头的参数值- [英] getopt not accepting argument value starting with hyphen -

问题描述

我的脚本具有选项o，该选项应接受参数作为值，如下所示

My script has an option o, which should accept argument as value, as below

./script -o '-p 2' ls

但是getopt不允许，给出错误

but getopt is not allowing, giving an error

Unrecognized option '-p 2'

代码段:

ARGS=$(getopt -a -n $0 -o o::h -- "$@")
   eval set -- "$ARGS"
   while true
   do
     case "$1" in
      -o) opt="$2"; echo "options: $2"; shift; shift;;
      -h) echo "$usage"; exit 0;;
      --) cmd="$2"; shift; break;;
     esac
   done

如何将参数作为值传递给脚本?

How can I pass arguments as value to script?
