Powershell Quick Hit - Doing it X times, again....

Continuing with the theme of using an easy array (1..20) with a forEach to do a code block a defined number of times, I cobbled this together yesterday. I can't figure out how to get the output on a single line yet, but it works; will ping entire subnet and report which ones respond.

(1..255) | % {
"192.168.0.$($_)"; Test-Connection "192.168.0.$($_)" -quiet -count 1 | % {
IF($_ -eq $True){"IP above pings"}

The % is an alias for ForEach
