我基本上想要一个Windows批处理脚本,通过一个服务器列表,并检查每个服务器与一个ping,如果它在线。 服务器列表应该是一个简单的纯文本文件,应该看起来像这样:
... "Google" www.google.com "Node1" 221.12.123.1 "Download Server" dl.myserver.com "Login Server" login.myserver.com ...
这是一个简单的程序应该做的事情:
输出应该如下所示:
... Google: online Stackoverflow: online Node1: online Download Server: offline Login server: offline ...
我只想知道这是甚至可以在(Windows)批处理和如何做到这一点。 如果批量不可能,我应该使用哪种编程语言? 是否有可能在Python中编程?
我也会非常感激,如果有人可以发布代码如何做到这一点,谢谢!
@echo off setlocal enableextensions enabledelayedexpansion for /f usebackq^ tokens^=1^,2^ delims^=^" %%a in ("servers.txt") do ( call :isOnline %%b && set "status=online" || set "status=offline" echo %%a : !status! ) endlocal exit /b :isOnline address setlocal enableextensions disabledelayedexpansion :: a temporary file is needed to capture ping output for later processing set "tempFile=%temp%\%~nx0.%random%.tmp" :: ping the indicated address and get errorlevel ping -w 1000 -n 4 %~1 > "%tempFile%" && set "pingError=" || set "pingError=1" :: When pinging, :: :: we get errorlevel = 1 when :: ipv4 - when any packet is lost.

这可以很容易地批量完成,只需要一些for /f
循环, echo
语句, if
语句, goto
/ call
语句和使用ping
命令。
1.将列表中所有服务器的描述列表打印到屏幕上。
您可以使用echo
声明,如echo "Google" www.google.com
2. ping第一台服务器服务器4次,如果一次ping成功,应该返回在线,如果所有4个ping失败,它应该离线。
在一个for /f
循环中[比如for /f "tokens=5 delims==, " %%p in (
]),你可以使用ping
命令和4个trys像这样ping -n 4 www.google.com
3.打印列表中第一个服务器旁边的在线或离线打印
你可以使用和if
statemenet在这里,如: if "%status%"=="online" echo Google: online
或只是echo Google: %status%
4.对列表中的所有其他服务器运行第2步和第3步。
您可以在此处使用goto
或call
语句(使用它像一个函数),例如: call :server_status_function www.google.com
