@echo off 


SC QUERY "ServiceName" 

echo %ERRORLEVEL%

rem 这两种写法是等价的，建议使用下面的写法，比较符合直觉
rem IF not ERRORLEVEL 1 GOTO EXIST
if %ERRORLEVEL%==0 GOTO EXIST
  GOTO NOTEXIST
  

  
:NOTEXIST
ECHO not exist "ServiceName" service


echo "test"

GOTO END

:EXIST

ECHO exist "ServiceName" service
GOTO END

:END
