如何从 Get-WMIObject 输出 powershell 中删除多余的行 [英] How to remove extra lines from Get-WMIObject output powershell

问题描述

我正在运行以下查询以获取视频驱动程序版本号

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

它返回我想要的数据加上大约 4 行.输出前 1 个，输出后 3 个.它看起来不会在帖子中正确显示.

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

推荐答案

如果要确定驱动程序版本，请忘记 Format-Table.只需这样做:

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

注意:您还可以为 Get-WmiObject 使用别名 gwmi，为 使用别名 select选择对象.但是请注意，根据您的环境，在脚本执行期间可能不存在别名.它们基本上是一种减少交互式控制台所需输入量的方法.

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.
