脚本用途：检测指定文件中的网站url，当一个网站down掉后，自动给指定的邮箱发信。
复制代码 代码如下:
#!/bin/bash
#website test scripts
while true;do
for cycle_temp in `cat url_list`
do
if lynx -dump `echo ${cycle_temp}` -accept_all_cookies|grep "true";then
echo "The website is running naturally"
else
echo "${cycle_temp} has been offline please attend it now!">/opt/test.txt
mail -v -s "website down mail" jbxue123@163.com < /opt/test.txt
fi
done
sleep 2s
done
url_list内容如下：
