powershell - Get-WmiObject to combine to outputs

Question

I was executing below script to obtain the server patch version of Skype for business servers.

I need the output as server patch name, version and computername.

$x = Get-Content "E:empservers.txt" 
foreach ($y in $x) 
{
Invoke-Command -ComputerName $y -scriptblock {Get-WmiObject -query ‘select name, version from win32_product’ | where {$_.name -like “*Skype for Business server 2015, core*”}} | Select-object name, Version, @{Name='ComputerName';Expression={$y}} | ft -AutoSize
}

But I am receiving output as below

Name                                            Version      ComputerName

I don't need my header tiles in every line of output. Any suggestions?

Answer 1

• You are getting headers for each computer because the select statement is inside the foreach loop.

• Invoke-command accepts multiple computers so you dont need a foreach loop.

• use server-side filtering where possible.

  $x = Get-Content "E:empservers.txt" 
  Invoke-Command -ComputerName $x -scriptblock {Get-WmiObject -query "select name, version from win32_product where name like 'Skype for Business server 2015, Core%'"} | 
   Select-object PSComputerName,name, Version
  

For future:

• Use Get-CimInstance because Get-wmiobject is deprecated.
• Do not use win32_product because it can potentially lead to msi corruption. Use the registry instead.
