Scriptul de ieri l-am extins si i-am adaugat functii de remote shutdown si restart. Ca bonus am adaugat si epic fail si putina validare.

#wakeonlan $computer
function WakeOnLan($computer)
{
	$select=$select |where-object {$_.computername -eq $computer} |Select-Object mac
	if ($select.mac -eq $null)
	{

	}
	else
	{
		$select.mac  -match "(..)(..)(..)(..)(..)(..)" | out-null
		$mac= [byte[]]($matches[1..6] |% {[int]"0x$_"})
		$UDPclient = new-Object System.Net.Sockets.UdpClient
		$UDPclient.Connect(([System.Net.IPAddress]::Broadcast),4000)
		$packet = [byte[]](,0xFF * 102)
		6..101 |% { $packet[$_] = $mac[($_%6)]}
		$UDPclient.Send($packet, $packet.Length)
		echo "workstation $computer is booting up..."
	}
