CMD/Batch获取活动接口名称作为变量 [英] CMD/Batch get active interface name as variable

问题描述

我目前很难弄清楚如何将活动接口名称作为变量输出，以后可以在代码中使用. 我一直在此处 a>一点，如何将cmd输出用作变量，但是我需要活动的特定名称.

I'm currently having a hard time figuring out how to get the active interface names as a variable output which can be later on used in the code. I've been reading here a bit, how to use the cmd output as a variable, but I need the specific names which are active.

我当前的代码:

    @echo off

    netsh interface show interface


    FOR /F "tokens=* USEBACKQ" %%F IN (`netsh interface show interface`) DO (
    SET var=%%F
    )
    ECHO %var%
    Pause

显示以下图像: 我们可以看到由于

Which displays this image: We can see that due to

netsh界面显示界面

netsh interface show interface

，显示了两个已连接的接口和两个未连接的接口.但是，我如何获得外汇. 以太网2和WiFi仅作为变量，例如%% V?

, two connected interfaces and two non connected are shown. However, how do i get f.ex. Ethernet 2 and WiFi as a variable only like %%V ?

推荐答案

以获取所有已连接接口的名称:

to get the names of all interfaces that are connected:

FOR /F "tokens=3,*" %%A IN ('netsh interface show interface^|find "Connected"') DO echo %%B

注意:这取决于语言.

对于独立于语言的解决方案，请使用wmic(具有其自身的陷阱和奇怪之处):

For a language independent solution use wmic (which has it's own traps and oddities):

for /f "tokens=2 delims==" %%a in ('wmic nic where (NetConnectionStatus^=2^) get name /value') do (
  for /f "delims=" %%b in ("%%a") do echo %%b
)

内部for用于处理难看的wmic行结尾

The inner for is to handle the ugly wmic line endings
