How to get the Nic name by batch processing
This article will explain in detail how to obtain the network card name for batch processing. Xiaobian thinks it is quite practical, so share it with you as a reference. I hope you can gain something after reading this article.
The code is as follows:
:: Use ipconfig /all to get the name of the network card.
FOR /F "tokens=2*" %%i IN ('ipconfig/all^|find /i "Ethernet adapter "') DO set name=%%j
:: Use the for command to remove the colon after the network card name.
FOR /F "tokens=1* delims=:" %%i in ("%name%") do set NIC name =%%i
Apply the above script to modify DNS, for example, yesterday the national DNS server crashed, DNS changed to 202.96.199.132 to restore normal Internet access.
Modify DNS Fragments
The code is as follows:
FOR /F "tokens=2*" %%i IN ('ipconfig/all^|find /i "Ethernet adapter "') DO set name=%%j
FOR /F "tokens=1* delims=:" %%i in ("%name%") do set NIC name =%%i
netsh -c interface ip add dns name="%NIC name %" addr=202.96.199.132 index=1
netsh -c interface ip add dns name="%NIC name %" addr=202.96.64.38 index=2
Modify IP, subnet mask, gateway, DNS code
The code is as follows:
FOR /F "tokens=2*" %%i IN ('ipconfig/all^|find /i "Ethernet adapter "') DO set name=%%j
FOR /F "tokens=1* delims=:" %%i in ("%name%") do set NIC name =%%i
netsh -c interface ip set address name="%NIC name %" source=static addr=192.168.1.215 mask=255.255.255.0
netsh -c interface ip set address name="%NIC name %" gateway=192.168.1.1 gwmetric=0
netsh -c interface ip add dns name="%NIC name %" addr=202.96.209.133 index=1
netsh -c interface ip add dns name="%NIC name %" addr=202.96.209.5 index=2
