Great Powershell One-liners

Or, 'highly useful things you can do in Powershell':

Watching the last 20 lines of the last (log?) file in a directory:
(gci)[-1] | gc | select-object -last 20
Finding where .Net is installed:
(get-itemproperty HKLM:\software\microsoft\.netframework).InstallRoot
Pinging a URL [1]:
$temp = (new-object net.webclient).DownloadString($url)
if ($?) { write-host Passed -foregroundcolor "green" }
Getting the DNS suffix for a machine:
(Get-WmiObject -class "Win32_ComputerSystem").Domain

[1] Ok, that one's not a one-liner.

[2] But it could be :

[PoSH]> if ((new-object net.webclient).DownloadString($url)) {write-host Passed -foregroundcolor "green
