RegEx with Powershell wrong? - windows

Question

So I have this PowerShell one-liner that gives me back my groups:
$groups = Get-ADPrincipalGroupMembership userName | ForEach-Object {Write-Host $_.Name -BackgroundColor Red} |Out-String; $groupsWithSpaces = foreach ($groups in $groupsWithSpaces) {Select-String -AllMatches '[\\s+,]' | Write-Host}; Write-Host $groupsWithSpaces
How am I using the regex wrong? I am trying to return only groups that have a whitespace on the end. I am always returning every group, and I only want the ones that have white space on the end. I can get true/false, but...help please.
Thanks!

Answer 1

In your regex you were escaping one of the slashes. Making it so you were looking for groups with a literal slash followed by at least on letter s.
If you are just trying to find the group with spaces in them this would work
Get-ADPrincipalGroupMembership username |
Where-Object{$_.Name -match "\s"} |
select -ExpandProperty Name |
Write-Host -BackgroundColor red
I formatted it for easy reading
If you wanted to see the whole list with the empty ones standing out you could also use and if statement
Get-ADPrincipalGroupMembership username | select -ExpandProperty Name | ForEach-Object{
If( $_ -match "\s"){
Write-Host $_ -BackgroundColor red
} Else {
Write-Host $_
}
}

I think this is the false variable --> $groupsWithSpaces = foreach ($groups in -->HERE<--$groupsWithSpaces-->HERE<--) {Select-String -AllMatches '[\\s+,]' | Write-Host}; Write-Host $groupsWithSpaces.
Work this one?
$groups = Get-ADPrincipalGroupMembership userName | ForEach-Object {Write-Host $_.Name -BackgroundColor Red} |Out-String; $groupsWithSpaces = foreach ($group in $groups) {If ($group[-1] -eq " ") {Write-Host $group}}; Write-Host $groupsWithSpaces
