修改Shell脚本以监视/ping多个IP地址 [英] Modify shell script to monitor/ping multiple ip addresses

问题描述

好的，所以我需要不断监视多台路由器和计算机，以确保它们保持在线状态.我在此处找到了一个很棒的脚本，该脚本会通过咆哮声通知我(所以我可以如果无法ping通单个IP，则会在我的手机上获得即时通知).我一直在尝试修改脚本以ping通多个地址，但运气不佳.我在尝试弄清如何对关闭的服务器执行ping操作时遇到了麻烦，而脚本一直在监视在线服务器.任何帮助将不胜感激.我没有做太多的Shell脚本编写工作，所以这对我来说是很新的.

Alright so I need to constantly monitor multiple routers and computers, to make sure they remain online. I have found a great script here that will notify me via growl(so i can get instant notifications on my phone) if a single ip cannot be pinged. I have been attempting to modify the script to ping multiple addresses, with little luck. I'm having trouble trying to figure out how to ping a down server while the script keeps watching the online servers. any help would be greatly appreciated. I haven't done much shell scripting so this is quite new to me.

谢谢

推荐答案

最简单的方法是将此脚本与另一个创建N个进程的脚本包装在一起.假设您的脚本称为"watchip"，然后将文本输入另一个脚本

The simplest approach is to wrap this script with another one that creates N processes. Assume your script is called "watchip", then put into another script the text

watchip 10.0.1.1 &
watchip 10.0.1.2 &
watchip 10.0.1.3 &
etc

，然后在watchip中将localip设置为$ 1.

and set localip to $1 inside watchip.
