    echo false

)

I want make netstat stetment output stored in variable d, and d became parameter from If cluse, What wrong with my file ?

Answer 1

You don't need to set a variable in your case.

This should work :

netstat -an | find /c "0.0.0.0:80" && echo true || echo False

But if you need to have this value in a variable you can do like this :

@echo off
for /f %%a in ('netstat -an ^| find /c "0.0.0.0:80"') do set D=%%a
if %D% equ 2 (
echo true
) else (
echo false)
