Invoke-Command AsJob参数设置不起作用

Question

I am able to do

Invoke-Command -ScriptBlock { Z:\\prog.bat }

However, when I do

Invoke-Command -ScriptBlock { Z:\\prog.bat } -AsJob

I keep getting

Invoke-Command : Parameter set cannot be resolved using the specified named parameters. At line:1 char:1 + Invoke-Command -ScriptBlock { z:\\prog.bat } - ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidArgument: (:) [Invoke-Command], ParameterBindingException + FullyQualifiedErrorId : AmbiguousParameterSet,Microsoft.PowerShell.Commands.InvokeCommandCommand

My intention is to run Z:\\Prog.bat in the background since I will be executing this thru Ansible

Per the comments, this error message is telling you that it's not possible for PowerShell to know which Parameter Set you are trying to use. A Parameter Set is a collection of Parameters that are used together, some mandatory and some optional. Some cmdlets have a single set, some cmdlets have different combinations allowing them to be used in different ways.

You are using -ScriptBlock and -AsJob . Invoke-Command has quite a large number of Parameter Sets and to make your call of these parameters unique you need to use them with one of these parameters:

• -Session
• -ComputerName
• -ConnectionUri
• -VMId
• -VMName
• -ContainerID

Eg:

Invoke-Command -ScriptBlock { Z:\prog.bat } -AsJob -Computername SomeComputer

Alternatively if you're just attempting to run a script block as a background job on your local machine, don't use Invoke-Command instead consider using Start-Job :

Start-Job { Z:\prog.bat }
