Hello Gents,

I've started studying powershell, i bought Learn Windows Powershell in a Month of Lunches, so please excuse my newbie questions.

So, i'm at chapter 9, the pipeline deeper and i'm always confused when i see the following:

1- Typename, when you do get-member, Don always emphasize the need to have an eye on that but i'm not sure what that is, and how can i use that information with piping

2- Since i don't have programming background the following also confuse me when i look at the parameters of a Cmdlet
Can someone please explain me what are the following:
a- Accept pipeline input? True (ByPropertyName) —- what is by propertyname and how different it is from ByValue
b- -DisplayName —- what is String ? and how different it is from SwitchParameter

3- In the help file, what are INPUTS and OUTPUTS, for example:
INPUTS
System.ServiceProcess.ServiceController, System.String
You can pipe a service object or a service name to this cmdlet.

OUTPUTS
System.ServiceProcess.ServiceController
This cmdlet returns objects that represent the services on the computer.

The problem is when i google them, i get a lot of scripts lol, so it's kind of hard to find an explination.

Thanks in advance ! 🙂

Jeff and I literally wrote a book about all that. "Learn PowerShell Scripting in a Month of Lunches." Available now on Manning.com :). Most of that's also covered in the about_ help files.
