石头剪刀布

#!/bin/bash
num=$[RANDOM%3]
echo "请根据下列提示选择您的出拳手势"
echo "1 石头"
echo "2 剪刀"
echo "3 布"
read -p "请选择1-3 " person
case $person in
1)
if [ $num -eq 0 ];then
echo "平局"
elif [ $num -eq 1 ];then
echo "你赢了"
else
echo "你输了"
fi;;
2)
if [ $num -eq 1 ];then
echo "平局"
elif [ $num -eq 2 ];then
echo "你赢了"
else
echo "你输了"
fi;;
3)
if [ $num -eq 2 ];then
echo "平局"
elif [ $num -eq 3 ];then
echo "你赢了"
else
echo "你输了"
fi;;
*)
echo "请输入1～3"
esac
二：第二种方法 ，定义了两个变量，一个是机器出的定义了y， 用户的定义为了x，然后做出三种判断，下面是代码：

#!/bin/bash
num=$[RANDOM%3+1]
case $num in
1)
y="石头";;
2)
y="剪刀";;
3)
y="布";;
esac

read -p "请输入石头、剪刀、布 ：" x
echo "机器出的是 : $y"
echo "你 出的 是 : $x"
if [ $x == $y ];then
echo "平手"
elif [[ $x == "石头" && $y == "剪刀" ]] ||
[[ $x == "剪刀" && $y == "布" ]] ||
[[ $x == "布" && $y == "石头" ]];then
echo "你赢了"
else
echo "你输了"
fi
