Windows7 Batch，第一次For循环后如何中断 [英] Windows7 Batch, how to break after first For loop

问题描述

我正在编写一个简单的脚本来检索作为IP给出的本地地址.

I'm writing a simple script to retreive my localhost address given as IP.

要获取我的IPv4地址(Win7)，我编写了简单的FOR循环，但结果是我从最后一个循环而不是第一个获取了IP.

To get my IPv4 address (Win7) I've written simple FOR loop, but as a result i get the IP from last loop instead of first one.

这是批处理代码:

cls
for /f "tokens=1-2 delims=:" %%a in ('ipconfig^|find "IPv4"') do (
  set ip=%%b
)
set ip=%ip:~1%
echo %ip%

这将返回:

(set ip= 192.168.1.101 )
(set ip= 192.168.88.1 )
(set ip= 192.168.137.1 )
set ip=192.168.137.1
echo 192.168.137.1
192.168.137.1

我需要的是第一个循环的结果:

What i need is the result of first loop:

192.168.1.101

推荐答案

那该代码又没有任何循环呢?

And what about this code without any loop ?

@Echo off
For /f "tokens=2 delims= " %%a in ('arp -a ^|findstr /i "Interface"') do (set IP=%%a)
Echo The IP adress is : %IP%
pause
