    Hi All,

    I'm trying to bulk create some new security groups by utilising the names of some existing ones in our AD.

    Essentially, all I'm looking to do is read in the name of the existing group and then append "-Shared" to the end of it when creating the new one.

    I'm thinking this will do the trick, however being a little cautious I wanted to throw this out there for review before I hit the button as -WhatIf doesn't work with script blocks.

    Get-ADGroup -Filter {name -like "<ExistingGroup>*"} | Select-Object name | ForEach-Object {New-ADGroup -Name "$_.-Shared" -DisplayName "$_.-Shared" -Description "Shared folder" -Path "<DistinguishedPathName>" -GroupCategory Security -GroupScope DomainLocal}

    Any expert advice would be greatly appreciated!

    Cheers.

    I would format the code better so that you can clearly see what's going on. The below code will get all the groups that have a category of "Seucrity" and put "-shared" onto the end of the name. Note that I am only writing to the console what the output would be, you would replace this with the "New-ADGroup" commandlet.

    $ExistingGroups = Get-ADGroup -Filter "(groupcategory -eq 'Security)"

foreach ($I in $ExistingGroups){
    $PreGroupName = $i.name
    
    Write-Host "$PreGroupName-Shared"
}

    Hope this helps :)
