The error tells you what is wrong. You are either missing a `}` or you have an extra somewhere. Since I am nice, I copied your code into my editor and took a look. You had 2 extra brackets. Download VScode with the bracket colorizer extension to avoid these
issues in the future. Here is what your code should look like.
Invoke-Command -ComputerName (Get-Content c:\temp\test-servers.txt) -ScriptBlock {get-wmiobject win32_process | where-object {($_.name -like "powershell.exe") -and ($_.name -like "notepad.exe")}} | select name,PSComputerName,@{n="owner";e={$_.getowner().user}} | Format-Table name,PSComputerName,owner -AutoSize
Break the code down to make it more readable like below:
$scriptBlock = {
get-wmiobject win32_process | where-object {($_.name -like "powershell.exe") -and ($_.name -like "notepad.exe")}
}
$computerNames = Get-Content c:\temp\test-servers.txt
Invoke-Command -ComputerName $computerNames -ScriptBlock $scriptBlock | select name,PSComputerName,@{n="owner";e={$_.getowner().user}} | Format-Table name,PSComputerName,owner -AutoSize
