基于shell写的猜数字游戏

#!/bin/bash
echo '提示:请在0-9里选一个数字输入'
while :
do
        N=5
        read -p 'please input a number:' n
        if [ $n -gt $N ]
        then
                echo 'the number is too big'
                echo '凉了呀，马飞！！！'
        elif [ $n -lt $N ]
        then
                echo 'the number is too small'
                echo '难受啦，马飞！！！'
        elif [ $n -eq $N ]
        then
                echo 'Winner Winner Chicken Dinner'
                echo '大吉大利，今晚吃鸡'
                break
        fi
done
