Ask everyone The content in 1.txt is: 123123 The content in 1.bat is: type 1.txt \|find "123123" echo %ERRORLEVEL% echo.type 1.txt \|find "123123" echo %ERRORLEVEL% The result returns 0 and 1, why not 0 and 0??

What is the purpose of the building "echo.type 1.txt"?

I'm not sure what you're up to, but the execution of echo.type 1.txt \|find "123123" is wrong, so it returns "1" type 1.txt \|find "123123" echo %ERRORLEVEL% echo "type 1.txt \|find "123123"" echo %ERRORLEVEL% pause

Thanks! Now it's okay. I want to use HOST to block URLs (block those that pop up a lot of ads when opening a web page) set list1=.\Website.txt 'Inside are ad URLs set list2=%windir%\system32\drivers\etc\hosts for /f "tokens=1,2 delims==" %%i in (%list1%) do ( set Website=%%i type !list2! \|find "!Website!" 1>2>nul if !ERRORLEVEL! neq 0 ( echo.127.0.0.1 !Website!>>!list2!) )
