Hi Guys,

I can't seem to use the -computer switch in powershell when I type a .net frame class e.g :

[System.Environment]::MachineName

[System.Environment]::OSVersion

[System.Environment]::GetEnvironmentVariables()

how can I do this - run these commands on a remote machine?

Also how can I retrieve a list of all that's available under the system class?

thank you in advance.

Parameters like -computername are a feature of specific cmdlets in PS.  Not all cmdlets have that parameter as it wouldn't make sense.  Neither would it make sense for all (or any?) types/classes to be able to reference a remote machine.

Your best option (IMO) for running these on a remote machine is PS Remoting.  Actually, I don't think I see any other option.

If you need to see all the static methods and properties available for a class run something like the following:
[system.environment] | gm -static

Open in new window

Is that what you're referring to?  Also, in case you're not aware, gm is an alias for Get-Member.

thank you, I wanted to include .net framework classes in a script, and there are multiple servers in question.

I have heard that cmdlets are actually .net framework classes, so I am wondering could there be a way to create a new cmdlet in .net and include the -computer switch?/

I really haven't studied it at such a low level.  There are so many .Net Framework classes - I'm not sure what you mean by you wanted to include them in a script.
I have heard that cmdlets are actually .net framework classes
I haven't heard that.  I can't say it isn't true, but it doesn't sound right.  Cmdlets are written in C# if I remember right, and though I'm sure they include references to .Net classes, I feel there's more to it than that.  It's definitely possible to write your own cmdlet (if you know how) and include whatever functionality you want.  However, unless you have the skills and desire to be a PowerShell developer, I would recommend that you use the functionality that is already there (as I mentioned, PS Remoting seems to fit the bill here).

thanks, problem with psremoting is that it has to enabled on every server, and I don't know if there is a quick way to do it without manually having to log into each one?

yea I really want to learn automation at an advanced level, therefore it seems like I need to lean c#.net too to become an expert.

so powershell developers make the cmdlets right for applications? example powercli used for VMware, would have been written by a powershell developer, the netapp storage also has a powershell module and this again would having been written by a powershell developer?

I'll try to answer your posts in order.

You can enable PS Remoting with Group Policy.  There's only two or three settings (depending on environment) that need to be configured.

You can automate a ton without writing your own cmdlets.  It depends on what you want to do.

I believe so, yes. (in answer to your last two posts)
I am not a PS developer, I'm a scripter, so there's little I could tell you about the developer side.
