Powershell script how to set a condition?

Question

PowerShell

Good afternoon. There is a script in which there is an addition of groups from a csv file

foreach($group in $Groups)
{
$create_group = New-ADGroup -Name $group.GroupName -groupScope $group.GroupScope -Path $group.ou
}

How to write a condition for checking existing groups?
There is also a code for adding a user to a group. Data is taken from csv file

foreach($line in $UserGroup)
{
$userGroup=$line.ADUsers -split ";"
$groupsList = $line.ADGroup

foreach($user in $line)
{
Add-ADGroupMember -Identity $groupsList -Members $userGroup
}
}

How can I add a user to a group and indicate this group to him as the primary (primary)?

Answer 1

1. Google "powershell if group exists".
2. Google "powershell how to add user to group" and "powershell change primary group".

Answer 3

1. Do you need it at all? well, there is already such a group, well, it will give an error ... what will change for the result?
2.

Set-ADUser -Replace @{primaryGroupID = $primaryGroupToken}

, where $primaryGroupToken is the corresponding attribute of the desired group.
