无法识别的选项 [英] Option not recognized

问题描述

我正在尝试使用案例声明来确定我是否有合法命令.看起来像这样:

I'm trying to use a case statement to determine if I have a legal command. It looks something like this:

function commandTest {
    case $1 in
    –score) echo "something";;
    *)      echo "unknown";;
    esac
}

现在，如果我使用这样的功能，它将无法正常工作. case尽管相同，但不能正确识别该字符串.

Now if I use the function like this, it doesn't work. case doesn't recognize the string correctly although it is identical.

$ commandTest "-score"
unknown

我在这里做错了什么?

What am I doing wrong here?

推荐答案

发布后，您的示例代码具有

As posted, your sample code has an en-dash (Unicode U+2013) in front of score, instead of a minus sign (ASCII 0x2D), which is preventing bash from matching the string -score

切换:

–score) echo "something" 

收件人:

-score) echo "something"
