Hi r/powershell,

I would like to know if there is a more elegant way to do this:

• $group_valid contains one ore more strings
• $Identity.Groups contains one or more strings
• the script should only run if one or more strings from $Identity.Groups are valid

Like this:

$group_valid = Get-Content -path "$PSScriptRoot\group_valid.txt"

$access = $false

foreach ($group in $group_valid) {
    if ($Identity.Groups -contains $group) {
        $access = $true
        break
    }
}

if(-not $access) {
    exit
}

# Do stuff

If $group_valid would only contain a sinlge string, this would work:

$group_valid = Get-Content -path "$PSScriptRoot\group_valid.txt"

if ($Identity.Groups -notcontains $group_valid) {
    exit
}

# Do stuff

Which is so much less 'overhead' and slick. Which options do I have?
