I get a lot of output on my screen.If I want only those lines which have physical addeess in text output or say line that have DNS Servers only in ouput. Then is there an easy way to do a grep on these in outout in Windows 10 cmd. Or suppose in above output I want to see only output for section Vmnet8

then how can I grep it?

Answer 1

I want only those lines which have physical addeess

ipconfig|findstr /r ":: [0-9]\."

filters for lines that contain :: (for IPv6 addresses) or <number><dot> (for IPv4 addresses)

(as you mentioned being a "Linux-Guy" - don't expect too much from findstr REGEX. It's just a small crippled subset of real REGEX - see findstr /? )

Answer 2

Download the free MOBAXTERM then navigate through your windows OS same as if you are using Linux. Then you will be able to use grep etc.

Answer 3

With the introduction of Windows Subsystem for Linux ( WSL ), you can use grep directly on ipconfig .

** I have limited knowledge on grep . Here is a basic example usage:

1. On the classic Windows Command Prompt , run:

   C:\\> ipconfig /all | wsl grep 'IPv4'

2. On a Linux Terminal ( eg Ubuntu on WSL ), run (notice the .exe extension):

   $ ipconfig.exe /all | grep 'IPv4'

Sample output

 IPv4 Address. . . . . . . . . . . : 192.198.100.1(Preferred)
 IPv4 Address. . . . . . . . . . . : 192.198.15.9(Preferred)
 IPv4 Address. . . . . . . . . . . : 192.198.89.1(Preferred)
