Y/N程序一直出错，请大家帮忙指点

# This program shows the user's choice

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
export PATH

read -p "Please input (Y/N): " yn
[ "$yn" == "Y" -o "$yn" == "y" ] && echo "OK, continue" && exit 0
[ "$yn" == "N" -o "$yn" == "n" ] && echo "Oh, interrupt!" && exit 0
echo "I don't know what your choice is" && exit 0


不管输入什么都显示这个，很奇怪，请各位指点，是不是我的VI有问题啊？


[: 10: y: unexpected operator
[: 11: y: unexpected operator
I don't know what your choice is

怎么木有人回阿？是我的问题太白痴了么？
请各位帮忙解答一下，难道是编译器的问题么？

我运行了一下代码没发现什么问题。你打开调试选项查看一下是哪里出了问题。

代码： 全选

sh -x 脚本名

谢谢，终于有人关注了，呵呵

#!/bin/bash
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
export PATH

read -p "Please input (Y/N): " yn
[ "$yn" == "Y" -o "$yn" == "y" ] && echo "OK,continue" && exit 0
[ "$yn" == "N" -o "$yn" == "n" ] && echo "Oh,interrput!" && exit 0
echo "I don't know what is your choice" && exit 0

我输入的是 y

+ PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/home/sean/bin
+ export PATH
+ read -p Please input (Y/N): yn
Please input (Y/N): y
+ [ y == Y -o y == y ]
[: 1: y: unexpected operator
+ [ y == N -o y == n ]
[: 1: y: unexpected operator
+ echo I don't know what is your choice
I don't know what is your choice
+ exit 0

输入 e

+ PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/home/sean/bin
+ export PATH
+ read -p Please input (Y/N): yn
Please input (Y/N): e
+ [ e == Y -o e == y ]
[: 1: e: unexpected operator
+ [ e == N -o e == n ]
[: 1: e: unexpected operator
+ echo I don't know what is your choice
I don't know what is your choice
+ exit 0


是不是我的编辑器出问题了？该怎么做呢？

[ e == Y -o e == y ]
[: 1: e: unexpected operator

仔细看了一下你的程序，发现一个问题。test中用于测试字符串是否相等用的是“=”而不是“==”，所以会提示出错。test用法详见http://www.freebsd.org/cgi/man.cgi?quer ... ormat=html
