Description

Hi,

I'm doing the PowerShell 3.0 MVA and I saw that in the command below, where the services should be listed first sorted by the status column then by the displayname column, it is sorted in descending order by default. When I ask to sort it using only the displayname column it works correctly.

Command:

Get-Service | Sort-Object status,displayname

Output:

Status Name             DisplayName
------ ----             -----------
Stopped hidserv            Acesso a Dispositivo de Interface H...
Stopped wmiApSrv         Adaptador de Desempenho WMI
Stopped AdobeFlashPlaye... Adobe Flash Player Update Service

I guess that this is by design.

Just do a
(get-Service)[0] | get-member
and you'll find out, that Status is not a String, but a System.ServiceProcess.ServiceControllerStatus, which is an enum (see http://msdn.microsoft.com/de-de/library/system.serviceprocess.servicecontrollerstatus.aspx for documentation).
As Stopped is defined as 0x00000001 and Running is 0x00000004, Stopped will be placed before Running when sorting ascendingly.


If you want to sort by the Status-String, you can simply cast the column to String:
Get-Service | Sort-Object {[string]$_.Status}
