Adding an IF statment?

Question

I have the following (functioning) script, which applies a FSRM quota template to a user wihtin the specified group.
I receive an error if the quota exists - how do I stop this behavior? (IF statement?)
If quota? dir? exists -exit? skip? --not sure about the command. I only want it to apply if it does NOT exist.
$group = [adsi]"LDAP://CN=<blank>"
$groupSearcher = New-Object DirectoryServices.DirectorySearcher($group)
$groupSearcher.PageSize = 1000
$results = $groupSearcher.FindOne()
#$results.properties.item("member")
$members = $results.properties.item("member")
foreach ($member in $members) {
$user = [adsi]"LDAP://$($member)"
$userSearcher = New-Object DirectoryServices.DirectorySearcher($user)
$userSearcher.PageSize = 1
$results = $userSearcher.FindOne()
$sAMAccountNames = $sAMAccountNames + $results.properties.item("sAMAccountName")
foreach ($sAMAccountName in $sAMAccountNames) {
Write-Host "Quotas being modified for $($sAMAccountName)"
New-FsrmQuota -Path "E:\Users\$($sAMAccountName)" -Template:"UserSQ"

Hi,
You could turn this into a function and then pass in the group name and the template, but this is a lazier way to do this:
Get-ADGroupMember -Identity 'GroupName' | ForEach {
If (!(Get-FsrmQuota -Path "E:\Users\$($_.SamAccountName)" -ErrorAction SilentlyContinue)) {
Write-Host "Quotas being modified for $($_.SamAccountName)"
New-FsrmQuota -Path "E:\Users\$($_.SamAccountName)" -Template:"UserSQ"
Else {
Write-Host "Quota was already set for $($_.SamAccountName)"
Get-ADGroupMember -Identity 'OtherGroupName' | ForEach {
If (!(Get-FsrmQuota -Path "E:\Users\$($_.SamAccountName)" -ErrorAction SilentlyContinue)) {
Write-Host "Quotas being modified for $($_.SamAccountName)"
New-FsrmQuota -Path "E:\Users\$($_.SamAccountName)" -Template:"OtherUserTemplate"
Else {
Write-Host "Quota was already set for $($_.SamAccountName)"
Get-ADGroupMember -Identity 'SomeOtherGroupName' | ForEach {
If (!(Get-FsrmQuota -Path "E:\Users\$($_.SamAccountName)" -ErrorAction SilentlyContinue)) {
Write-Host "Quotas being modified for $($_.SamAccountName)"
New-FsrmQuota -Path "E:\Users\$($_.SamAccountName)" -Template:"YouGetTheIdea"
Else {
Write-Host "Quota was already set for $($_.SamAccountName)"
Just create 8 blocks and go from there. I'm using Get-ADGroupMember from the AD module as opposed to the ADSI method you were using to get the group members. It's just a tad shorter. =]
