vi ceshi.sh

PRICE=$(expr $RANDOM % 100)
TIMES=0
read -p "你能几次猜中答案呢? " q
echo "商品价格范围0~99，猜猜是多少?"
while [ $TIMES -lt $q ]

let TIMES++
if [ $x -eq $PRICE ]
then
echo "恭喜您答对了"
echo "您猜了$TIMES次"
exit 0
elif [ $x -gt $PRICE ]
then

else

fi
done
read -p "是否重新尝试(y/n) " n
if [ $n = "y" ]
then
sh /root/ceshi.sh
