I need a Powershell script that will delete all Ad Groups in a text file with verification.  I have 100's of groups in the text file that include local and global groups.  I will award points asap.

Thanks!

What kinds of verification do you need ?

Do you need a prompt to answer Yes or No before completing the step ?


Easy one liner
gc files.txt | % {
get-adgroup -filter 'Name -like $_ | remove-adgroup -whatif
}

Open in new window


Above will remove without prompting

Alternatively in order to have a clean environment you can also perform the below steps

Query to verify the group exists
Delete all members from the group
Then delete the group from AD

gc files.txt | % {
$gname = $_
Get-ADGroupMember $gname | % {Remove-ADGroupMember $_ $_ -Confirm:$false}
get-adgroup -filter 'Name -like $gname | remove-adgroup 
}

Open in new window

I don't need a confirmation.  Your second script will work, but...

I tried running the 2nd script, but got this error...


get-adgroup -filter 'Name -like $gname | remove-adgroup}
+                     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The string is missing the terminator: '.
At C:\test\deletegroups.ps1:1 char:19
+ gc groups.txt | % {
+                   ~
Missing closing '}' in statement block.
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
