Batch script: how to check for admin rights

Question

How do I check if the current batch script has admin rights?

I know how to make it call itself with runas but not how to check for admin rights. The only solutions I've seen are crude hack jobs.

Answer 1

You could always do something like this

mkdir "%windir%\system32\test" 2>nul
if "%errorlevel%" == "0" (rmdir "%windir%\system32\test" & echo Is admin) else (echo Not an Admin)

Not the best of ways but works for me all the time.

Answer 2

This is the best kludge I could think of, using standard commands:

net user %username% | findstr /r Administrator.
if %errorlevel% == 1 (
echo This is not an admin account
) else (
echo This is an admin account
)
