I'm trying to run a PowerShell from command prompt but received an error.
PS in command prompt:
powershell -command "Get-Date (Invoke-Command { (New-Object -com """Microsoft.Update.AutoUpdate""").Results.LastInstallationSuccessDate} -ErrorAction SilentlyContinue).date -format yyyyMMdd | Out-File -FilePath C:\temp\winupdatelatest.txt"
Error:

The intention is to create a folder on a remote computer C drive.
I'm trying to run this:
$stageSvrs | %{
Invoke-Command -ComputerName $_ -ScriptBlock {
$setupFolder = "c:\Support\test1"
Write-Host "Creating Support Folder"
New-Item -Path $setupFolder -type directory -Force
Write-Host "Folder creation complete"
}
}
but I get the following error:
Invoke-Command : Cannot validate argument on parameter 'ComputerName'. The argument is null or empty.
Provide an argument that is not null or empty, and then try the command again.

Well, i'm trying to execute a script with another credentials and i got the next error:
You cannot call a method on a null-valued expression.
At C:\Automation\SoftwareInstallation\runas_test\whoami_test.ps1:10 char:1
+ Write-Host $result.StandardOutput.ReadToEnd()
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : InvokeMethodOnNull
This is my code:
$username = 'idb\frida_automation_scc'
$pass = Get-Content -Path C:\Automation\SoftwareInstallation\runas_test\settings.txt -Raw
$password = ConvertTo-SecureString $pass -AsPlainText -Force
$MyCredential=New-Object -TypeName PSCredential -ArgumentList $username, $password
$result=Start-Process -NoNewWindow powershell.exe -ArgumentList "-file C:\Automation\SoftwareInstallation\runas_test\whoami_test2.ps1" -Credential $MyCredential -PassThru -RedirectStandardOutput test1.txt
Write-Host $result.StandardOutput.ReadToEnd()
And this is the another command:
$result= whoami
Write-Host $result
return $result
I don´t know why this error happens if the command are well written and the script brought back the value in a .txt file.
I am running this Script to get the directory listing
It was working few days ago but I keep having this error

Not sure what I am doing wrong here - probably a stupid mistake, but I put a condition around the Start-Job statement, and powershell still gives the following error:

In v3 add $using:

You have already used a variable for a script block once with $testScriptBlock. You could just do that again for -InitializationScript?
$anotherSB = [scriptblock]::create("$commonElements = (Get-Content -Path $commonElementsLocation)")
$result += Start-Job -InitializationScript $anotherSB -ScriptBlock $testScriptBlock -ArgumentList "testing" | Wait-Job | Receive-Job
When I run the following command in command line
powershell.exe "Import-Module ActiveDirectory;New-ADUser -name "rr"
-path "OU=Test,DC=Example,DC=com"
I get the error below:
New-ADUser : Cannot convert 'System.Object[]' to the type 'System.String' required by parameter 'Path'. Specified method is not supported.

Try this:
powershell.exe "Import-Module ActiveDirectory;New-ADUser -name 'rr' `
-path 'OU=Test,DC=Example,DC=com'"
