Passing array to -FilePath parameter in PowerShell

Question

I'm using invoke-command to execute a list of scripts on remote servers. I'm using a variable array to specify the scripts.

$Modules = Get-Content "Modules\Modules.txt"
$ModulePath = "Modules\" + $Module
Invoke-Command server -FilePath $ModulePath

This gives me an error: Invoke-Command : The value of the FilePath parameter must be a Windows PowerShell script file. Enter the path to a file with a .ps1 file name extension and try the command again. Parameter name: filePath

If I replace the array with the absolute path to an individual script file, it works without issue.

Thanks!

Have you tried outputting $ModulePath to see exactly what it is you're sending to that parameter? — mjolinor

I have. The string output is the full path to the script file. — user3638757

No, it takes a single string only

-FilePath <String>

Maybe try something like this:

Get-Content "Modules\Modules.txt" | foreach { invoke-Command "Modules\$_" }

Tried that with same results. Interesting to note. If I change $ModulePath to the full path of a single script it works. For example: $ModulePath = ".\Modules\Test.ps1"

Ok, that's right. My bad there. PowerShell will attempt to run from either its program folder or System32 (if in admin mode) if you don't specify the current dir. Glad it's working for you.
