How to remove extra lines from Get-WMIObject output powershell


I am running the following query to get the video driver version number

Get-WmiObject Win32_videoController | where {$_.Name -like "Nvidia*"} | Format-table -HideTableHeaders DriverVersion

It returns the data I want plus about 4 extra lines. One before the output and 3 after. It doesn't look like it's going to show up properly in the post.

PS F:\> 
Get-WmiObject Win32_videoController | where {$_.Name -like "Nvidia*"} | Format-table -HideTableHeaders DriverVersion

9.18.13.3250

Solution

  • If you want to determine the driver version, forget about Format-Table. Simply do this:

    Get-WmiObject Win32_VideoController -Filter "Name LIKE 'Nvidia%'" |
      Select-Object -Expand DriverVersion
    

    Note: You can also use the aliases gwmi for Get-WmiObject and select for Select-Object. Beware, though, that aliases may not be present during script execution depending on your environment. They're basically a means to reduce the amount of typing required in an interactive console.
