How to split command output in Windows command prompt?

Question

Is there a split command in Windows, to split command output? My command is:

ipconfig | findstr /i \"Default gateway\" | findstr [0-9]
         


        

Answer 1

On my computer, there are two gateways returned, one for IPv4 and one for IPv6. The findstr doesn't distinguish between them. However, for me IPv4 is returned before IPv6. This batch file extracts the IP address for the gateway from the findstr output:

@echo off

setlocal ENABLEDELAYEDEXPANSION

for /f "tokens=2 delims=:" %%i in ('ipconfig ^| findstr "Default gateway"') do (
  if not defined _ip set _ip=%%i
)
for /f "tokens=1 delims= " %%i in ("!_ip!") do (
  set _ip=%%i
)

echo !_ip!

endlocal & set yourvar=%_ip%

I split it into two separate for commands (instead of nesting the for commands) so that I could just grab the first 'gateway' returned from the findstr. The result has a leading space, so the 2nd for command removes the leading space. The & set yourvar=%_ip% at the end is how you pass a local variable outside of the local block, but you don't have to use that...
