linux switch 都可以传入什么类型，分别给出案例

Linux 的 switch 指令可以传入字符串或整数。

案例1 (字符串):

switch ($string) {
    case "value1":
        # code to be executed if $string == "value1"
        break;
    case "value2":
        # code to be executed if $string == "value2"
        break;
    default:
        # code to be executed if $string is not equal to any of the above
}

案例2 (整数):

switch ($number) {
    case 1:
        # code to be executed if $number == 1
        break;
    case 2:
        # code to be executed if $number == 2
        break;
    default:
        # code to be executed if $number is not equal to any of the above
}

注意：上述例子中的语言是bash 脚本语言.
