I am creating sites through powershell and creating the groups for them. I have a situation where if the group is already existing group then I have to add that group to the site. Coz might be possible the site is not present and the group is present. For ex: the site name is "xyz" and the group name is "xyz_admin". Here if the group is already existing group while creating the site then I have to add it to the site.
I am adding the group like this:
Add-SPGroup.ps1 -url $url -Group ($webname+"_admins") -Role "Fuld kontrol" -Owner $global:loginName
but it gives me an error when the group is present.
Any help is appreciated in this aspect.
Thanks in advance.
