[：在shell编程意外的运营商 [英] [ :Unexpected operator in shell programming

问题描述

我的code：

    #!/bin/sh
    #filename:choose.sh
    read choose
    [ "$choose" == "y" -o "$choose" == "Y" ] && echo "Yes" && exit 0
    [ "$choose" == "n" -o "$choose" == "N" ] && echo "No"  && exit 0
    echo "Wrong Input" && exit 0

但是，当我执行

    sh ./choose.sh

终端提示我，

   [: 4: n: :Unexpected operator
   [: 5: n: :Unexpected operator

有没有在我的bash脚本什么错误？
谢谢！

Is there any mistake in my bash script? Thanks!

推荐答案

有在您的庆典脚本没有错。但你和执行它的 SH 其中有一个可大可小的语法;）

There is no mistake in your bash script. But you are executing it with sh which has a less extensive syntax ;)

所以，运行庆典./choose.sh 来代替：）
