Today Denis St-Pierre informed me that this change of working directory also occurs when a batch file is running in elevated mode in Windows Vista, Windows Server 2008 or Windows 7. Without this PUSHD command, the start/working directory of the batch file will be changed to %windir%\System32. I use PUSHD "%~dp0" ever since, as the first command in any batch file that could be run from a UNC path. Remember Reinhard Irnberger's PUSHD trick to automatically map a drive if a UNC path is specified?.He is back with Add.bat, a batch file to add 2 positive integers of up to 2000 digits each (I did test that!). Remember Brian Williams' big number math batch files?.Write-Error "This script must be executed in admin mode." -ErrorAction Stop
If ( -not ($currentPrincipal.IsInRole( ::Administrator ) ) ) $currentPrincipal = New-Object ( ::GetCurrent( ) ) ::Test If script has Admin Priviledges/is elevatedĮCHO you are NOT Administrator. On Error Goto 0 'Turn error reporting back on (and clears Err object)

Here are some code snippets to check inside the script. Noobs admins don't always right-click and run as administrator so you must check.

With Windows 7 you have 2 security token when you login with admin. Sometimes you have to be running with admin privileges to get something done. This time, he sent me a couple of script snippets to check if the current script is running with administative (elevated) privileges:
Denis St-Pierre often shares the results of his research.>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"Įcho Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"Įcho UAC.ShellExecute "%~s0", "", "", "runas", 1 > "%temp%\getadmin.vbs" Here is how I use it, in Evan's routine /site/eneerge/scripts/batchgotadmin that elevates a batch script itself: So it yields the same errorlevel now as when run without Admin privileges. Not enough storage is available to process this command. trick for checking for elevation suddenly stopped to work for me:Ĭopyright (c) 2006 Microsoft Corporation. I'm not sure the problem could not have been solved ( AT depends on a service that is often disabled I often use OPENFILES instead to check for elevated privileges), but it did make him look for and find a way to not only check elevation level, but raise it as well: The great advantage of this method compared to using OPENFILES is that the WHOAMI method will work in both 32-bit or 64-bit processes in 64-bit Windows.Īaron Thoma had a problem using Denis St-Pierre's elevation check. Whoami /groups | find "12288" || echo Not Elevated Whoami /groups | find "12288" & echo Elevated Or if you prefer to solve this as complicated as possible, use the short command name:įOR %%A IN ("somecommand") DO CMD /C %%~sA "argument1" "argument2"Īnother brilliantly simple way to check for elevated privileges, by Kevin Ridenhour: Jacques Bensimon ran into this quirk when trying to use a batch command in a context menu.Īfter searching and experimenting for a long time, he came up with a brilliantly simple solution: don't let the first character be a doublequote, just insert an before the first doublequote (sorry, whitespace won't work):īased on Jacques' findings I started doing some experiments, and found the following alternative work-arounds:ĬMD /C ("somecommand" "argument1" "argument2")ĬMD /C ""somecommand" "argument1" "argument2"" If the command line following CMD /C or CMD /K starts as well as ends with a doublequote, that entire command line is interpreted as a single (command) string. Note the missing outer doublequotes in the error message. 'somecommand" "argument1" "argument2' is not recognized as an internal or external command, operable program or batch file. It will return an error message like this one: Solutions found on .Įvery now and then a real "jewel" is sent to me by mail or otherwise.Ī selection of these tricks will be displayed on this page.ĬMD /C "somecommand" "argument1" "argument2" Many clever tricks are mentioned on my other pages, e.g. VoltCraft Energy Logger 3500 Configuration.Exploring the Youless LS120 Energy Monitor.
