在ping输出中将IP与文本分开?

本文介绍了在ping输出中将IP与文本分开?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我希望能够运行一个批处理文件，该文件将找到连接到路由器的每个设备的IP地址，然后从中查找其主机名.到目前为止，我的情况如下:

I'd like to be able to run a single batch file that would find the IP address of every device connected to my router, and then find their hostnames from it. What I have so far is below:

@echo off set /a n=0 :repeat set /a n+=1 echo 192.168.1.%n% ping -n 1 -w 500 192.168.1.%n% | FIND /i "Reply">>devices.txt if %n% lss 254 goto repeat type devices.txt goto :hostname

这将找到所有可能的地址，并将它们写入文本文件devices.txt. 但是，我现在得到以下结果:

This finds all the possible addresses and writes them to a text file, devices.txt. However, I now end up with the following:

Reply from 192.168.1.82: bytes=32 time=5ms TTL=255

批处理文件的下一部分是:

The next part of the batch file goes:

:hostname ping -a %ip% -l 1 -n 1 >> hostnames.txt

这会ping在devices.txt中找到的IP，并在hostnames.txt中返回结果-至少，我希望这样做.

This pings the IPs found in devices.txt and returns the result in hostnames.txt - or at least, I'd like it to.

在将IP地址写入devices.txt时，我需要以某种方式将IP地址与其他文本分开，然后将其分配为变量，以便下一部分可以使用它.

Somehow I need to separate the IP address from the other text when writing it to devices.txt, and then assign it as a variable so it can be used by the next part.

我可以用一个简单的功能来做这两个事情吗?

Is there a simple function I can use to do either of these things?

推荐答案

尝试一下:

@echo off setlocal set "p=ping -n 1 -w 500 192.168.1" for /l %%a in (1,1,254) do ( for /f "Tokens=3 delims=: " %%b in ( '%p%.%%a^|Find /i "TTL="' ) do ( echo Pinging %%b echo %%b>>devices.txt for /f "tokens=2" %%c in ( 'ping -a %%b -l 1 -n 1^|Find /i "pinging"') do ( echo %%c >>hostnames.txt ) ) )

我们首先创建一个以1为增量从1到254的For/L循环，然后在ping命令上运行for循环，该命令在返回行上获取第三个标记并将其放入变量％在这种情况下为％b.然后，我们回显%% b中包含的ping IP地址，并将其写入devices.txt.然后，我们运行另一个ping来提取第二个令牌，它是我们要ping的计算机的主机名，并将其写到hostnames.txt中.

We start by creating a For /L loop that goes from 1 to 254 in increments of 1. Then we run a for loop on a ping command that takes the third token on the return line and puts it into a variable, %%b in this case. We then echo out pinging IP address contained in %%b and write it to devices.txt. Then, we run another ping to extract the second token which is the hostname of the computer we're pinging and write it out to hostnames.txt.
