一个用Shell脚本写的猜丁壳游戏

为什么80%的码农都做不了架构师？>>> 一个用Shell脚本写的猜丁壳游戏-编程知识网

这几天在学习Linux的Shell脚本，写了一个猜丁壳游戏。

游戏规则：每回合玩家和电脑各出石头、剪子、布中的一个，分别以0、1、2表示，规定石头可以胜过剪子、剪子可以胜过布、布可以胜过石头，如果玩家和电脑所出相同，则进入下一回合继续比试，否则游戏结束，本回合的胜者即为游戏的获胜方。

#!/bin/sh# generate random numbers
function rand()
{min=$1max=$(($2-$min+1))num=$(($RANDOM+10000))echo $(($num%$max+$min))
}result=0
echo "Game Start!"
