在将参数传递给 PS 文件时，如何使用 invoke-command 从 windows 命令行运行 PS 文件？

Question

How do I use invoke-command to run a PS file from the windows command line while passing parameters to the PS file? This is my script:

#TestParams2.ps1

param (
    [string]$Server,
    [string]$FileFolderName,
    [string]$VerValue
)

$Server
$FileFolderName
$VerValue

And this is how I'm trying to call it:

powershell.exe invoke-command -FilePath 'C:\temp\TestParams2.ps1' -ArgumentList 'myserver','\\server1\folder name\file.txt','9999'

And when I run it, I get this:

Invoke-Command : Parameter set cannot be resolved using the specified named parameters.
At line:1 char:1
+ invoke-command -FilePath 'C:\temp\TestParams2.ps1' -ArgumentList 'mys ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Invoke-Command], ParameterBindingException
    + FullyQualifiedErrorId : AmbiguousParameterSet,Microsoft.PowerShell.Commands.InvokeCommandCommand

How should I call the script?

Answer 1

zdan's answer contains the crucial pointer: the -FilePath parameter is only meant to be used in the context of remoting , so you cannot use it unless you also specify the -ComputerName parameter.

However, using -ComputerName just so you can target the local machine is (a) inefficient and (b), more importantly, requires running as admin (elevated).

You don't need Invoke-Command at all; instead, call your script with the -File CLI parameter , passing the arguments as usual, separated with spaces:

powershell.exe -File C:\temp\TestParams2.ps1 myserver "\\server1\folder name\file.txt" 9999

If you also need to bypass the effective execution policy :

Caveat : If the effective execution policy is controlled by a Group Policy , it cannot be overridden.

powershell.exe -ExecutionPolicy Bypass -File C:\temp\TestParams2.ps1 myserver "\\server1\folder name\file.txt" 9999

Note that -ExecutionPolicy Bypass must be placed before the -File parameter (applies analogously to use of the -Command parameter) - anything after -File is considered the target script path plus any arguments to pass through to it.

Answer 2

The error is complaining that the set of parameters that you supplied to invoke-command is not complete such that it could not resolve which parameter set to invoke-command to apply.

In this case, when you specify the -FilePath argument, you must supply -ComputerName as well:

powershell.exe invoke-command -FilePath 'C:\temp\TestParams2.ps1' -ArgumentList 'myserver','\\server1\folder name\file.txt','9999' -ComputerName localhost

Answer 3

You have 2 options here.

Option 1: Specify the arguments on your call

powershell.exe invoke-command -FilePath 'C:\temp\TestParams2.ps1' -Server 'myserver' -FileFolderName'\\server1\folder name\file.txt' -VerValue '9999' 

Option 2: Enable positional parameters

Change your Script params to:

param (
    [Parameter(Position = 0)]
    [string]$Server,
    [Parameter(Position = 1)]
    [string]$FileFolderName,
    [Parameter(Position = 2)]
    [string]$VerValue
)

Then call your script like this:

powershell.exe invoke-command -FilePath 'C:\temp\TestParams2.ps1' 'myserver' '\\server1\folder name\file.txt' '9999'
