I have a powershell script that occasionally fails on systems that aren't running it with the correct account.

What I want to do is put a check at the beginning of the script to check that the user running the script has admin rights.

In Linux bash scripts I'd use something like this:

if [ "$(id -u)" != "0" ]; then

 I've run a few internet searches but I've not been able to find anything...
What is the powershell equivelant to this?

any help would be much appreciated

Hi,

Here's one method you can use:

Hi The Bellsprout,

In addition, the function below may be helpful for you to check whether the user running the script has the admin right

function Test-IsAdmin {
    try {
        $identity = [Security.Principal.WindowsIdentity]::GetCurrent()
        $principal = New-Object Security.Principal.WindowsPrincipal -ArgumentList $identity
        return $principal.IsInRole( [Security.Principal.WindowsBuiltInRole]::Administrator )
    } catch {
        throw "Failed to determine if the current user has elevated privileges. The error was: '{0}'." -f $_
    }
}

I hope this helps.
