FOR /F issue running from a text file

I seem to experience an issue with the code underneath:

@echo off
FOR /F "tokens=1" %%a IN (logs\reachable.txt) do echo %%a && set ip=%%a && call :process


:process

FOR /F "usebackq tokens=2 delims=[]" %%i in (`ping -n 1 %ip%`) 开发者_运维知识库do set myip=%%i && set ip=
echo %myip%


call :end

:end
exit /b

The code is working fine but the last one in reachable.txt (ping) is displayed twice.

Does anybody have an idea how to resolve this?

Thanks in advance.

It's because, once your first for loop is done, it's dropping through to the code beneath.

Replace:

@echo off
FOR /F "tokens=1" %%a IN (logs\reachable.txt) do echo %%a && set ip=%%a && call :process

:process
rem will be called from 'for' above AND when 'for' is done

with something like:

@echo off
FOR /F "tokens=1" %%a IN (logs\reachable.txt) do echo %%a && set ip=%%a && call :process
goto :eof

:process
rem will be called from 'for' above but NOT after 'for' is done

so that it doesn't drop through.
