In the final part of our mini-series, we add pipeline awareness to our super-fast Test-OnlineFast function. You now can pipe computer names into the function like this:
PS> 1..200 | ForEach-Object { "192.168.189.$_" } | Test-OnlineFast
Address Online DNSName Status
------- ------ ------- ------
192.168.189.200 True DESKTOP-7AAMJLF.fritz.box Success
192.168.189.1 True fritz.box Success
192.168.189.65 True mbecker-netbook.fritz.box Success
192.168.189.29 True fritz.repeater Success
192.168.189.64 True android-6868316cec604d25.fritz.box Success
192.168.189.112 True Galaxy-S8.fritz.box Success
192.168.189.142 True Galaxy-S8.fritz.box Success
192.168.189.129 True iPhonevMuzaffer.fritz.box Success
192.168.189.10 False Request Timed Out
192.168.189.100 False Request Timed Out
(...)
Of course, you can still use the function with plain parameters as well:
PS> Test-OnlineFast -ComputerName google.de, microsoft.com, 127.0.0.1 Address Online DNSName Status ------- ------ ------- ------ 127.0.0.1 True DESKTOP-7AAMJLF Success google.de True google.de Success microsoft.com False Request Timed Out
And you can even use results from other cmdlets, provided you select the property you want to pass on to the function. The line below pings all computers in your Active Directory (you better limit this a bit or else might run out of resources):
PS> Get-ADComputer -Filter * | Select-Object -ExpandProperty DnsHostName | Test-OnlineFast
