请教大家一个shell中的流程问题

Joker_cn

我需要定期使用curl判断我的服务器的状态：

1. 
   
2. curl -w "%{http_code}"  http://www.myserver.com/ | grep -o 200$ | wc -l
   

复制代码

如果正常就返回1，如果不正常，就返回0

请问我怎样把这个加入到一个if-else-fi中去，如果正常的时候，不进行操作，如果不正常，就发一封邮件给我。

主要想知道怎么使用一个命令的结果，作为另一个if中的条件。

谢谢！

我查了很多资料，可能是基础不好，还没搞明白，希望大侠们指教。因为很紧急

祝论坛上的朋友们端午节快乐！

The Battered-Body Trick
　　This is a story from Three Kingdoms that happened before the Battle of Chibi. One night， Zhou Yu was thinking hard in his tent about how to defeat Cao Cao's army， when Huang Gai came in . He suggested attacking with fire. “Well， it's exactly what I mean to do.” Said Zhou Yu. “That's why I'm keeping those two spies： to convey false information to Cao's camp. But I need a man to play the same game for us.” Huang Gai said he was willing to do it. They decided to carry out the trick of being flogged to win the enemy's confidence.

弱弱的文句 ”grep -o 200$“

200后面的$是干什么用的？
