no quite sure why wasn't working.  anyway worked out blank lines 1 char in length, knows char is? :-)

$result

$linearray =@()

$lines = (($result -replace '((udp|tcp) \d{3})', "`$1`n") -split "`n")

$lines = $lines | select -last 10
foreach ($line in $lines){if ($line.length -gt 1){ $linearray += $line }}
