How to test Get-ChildItem for no files as part of Invoke-Command?

I have the following script:

try {
Invoke-Command -Computer $Server -ScriptBlock { 
    param ($dir, $name)
    Get-ChildItem -Path $dir | 
        Where {$_.Name -Match "$name"} | 
            Remove-Item -confirm:$false -Recurse -Verbose 
} -ArgumentList $Directory, $DB

    Write-Host "`r`nsuccessfull! " -foregroundcolor yellow -backgroundcolor black
}
catch {
    write-host "`r`nFAILED!" -foregroundcolor red -backgroundcolor black
    Write-Host "$($error[0])`r`n" -foregroundcolor magenta -backgroundcolor black
}

if no files exist to delete...it currently still says "successful" as output...can i refine this to say "there was no files to delete" else "successfully deleted x number of files"?

also, the recurse on verbose is needed because otherwise i am forced to manually confirm even with confirm parameter. I think its because there are many sub items inside the target folder(s) i am looking to delete...

however, i get a TON of verbose messages for every single one of those items saying

VERBOSE: Performing the operation "Remove Directory" on target \name1\subitem

VERBOSE: Performing the operation "Remove Directory" on target \name1\subitem1

VERBOSE: Performing the operation "Remove Directory" on target \name1\subitem2

can i make it so that it just prints verbose on a folder level instead for every single item?

VERBOSE: Performing the operation "Remove Directory" on target \name1

Assign your file list to a variable that you can then inspect. Throwing everything through the pipeline is fine for quick-and-dirty, but not so much if you want to extract status information at various points.

$delfiles = Get-ChildItem -Path $dir | Where {$_.Name -Match "$name"} 
If ($delfiles) {
    Write-Host "There are $($delfiles.count) to delete " 
    $delfiles | Remove-Item -confirm:$false -Recurse #put a try/catch here maybe
    Write-Host "`r`nsuccessful! "    
}
else {
    write-host "there were no files to delete"
}
