How to Verify Administrative Rights in a Windows Batch Script

| Comments

While working on automated provisioning of a Jenkins slave server on Windows, I needed to verify that one of my batch scripts was running with administrative privileges.

Turns out this problem is easy to solve these days as long as you don’t need to support XP. Thanks to and31415 on SO for the great post on using fsutil!

@ECHO OFF
SETLOCAL ENABLEEXTENSIONS

:: verify we have admin privileges
CALL :IsAdmin || (ECHO %~n0: ERROR - administrative privileges required && EXIT /B 1)

ECHO "Hello, Admin!"

:EXIT
EXIT /B

:: function to verify admin/UAC privileges

:IsAdmin
IF NOT EXIST "%SYSTEMROOT%\system32\fsutil.exe" (
  ECHO %~n0: WARNING - fsutil command not found; cannot verify adminstrative rights
) ELSE (
  "%SYSTEMROOT%\system32\fsutil.exe" dirty query "%SystemDrive%" >NUL 2>&1
)
EXIT /B
