Question

在PowerShell中，输入“pnputil.exe -e”后，我会得到一个驱动程序信息列表，如下所示。我需要从列表中获取类监视器的已发布名称，并将“oem8.inf”存储到$monitor_name中。我可以使用哪个命令来搜索class = monitor并将其发布的名称提取到变量中。因为“已发布名称”属性有空格，所以我不知道如何使其工作。

Published name :            oem8.inf    
Driver package provider :   HP
Class :                     Monitors
Driver date and version :   07/25/2013 2.2.0.0    
Signer name :               Microsoft Windows Hardware Compatibility Publisher

Published name :            oem6.inf
Driver package provider :   Canon
Class :                     Printers
Driver date and version :   06/21/2006 6.1.7600.16385
Signer name :               Microsoft Windows

Published name :            oem1.inf
Driver package provider :   Microsoft
Class :                     Printers
Driver date and version :   06/21/2006 10.0.14393.0
Signer name :               Microsoft Windows

Answer 1

ConnorLSW's helpful answer是要走的路，他的方法说明了一个重点：

如果您使用 PowerShell cmdlet ，则无需字符串操作以提取信息 - PowerShell的对象 - 与传统的输出文本解析技术相比，面向本质的解决方案可以提供更强大，更方便的解决方案。

如果需要，PowerShell还具有强大的字符串解析功能：

$monitor_name = pnputil.exe -e | Select-String -Context 2 'Class :\s+ Monitors' | 
  ForEach-Object { ($_.Context.PreContext[0] -split ' : +')[1] }

通过输入样本，可以得到：

oem8.inf

Answer 2

您可以使用WMI通过Get-WMIObject cmdlet（别名gwmi）执行此操作：

gwmi Win32_PnPSignedDriver | ? DeviceClass -eq "MONITOR"

将返回一些详细信息，您可以使用以下内容将其缩小到InfName：

gwmi win32_PnPSignedDriver | ? DeviceClass -eq "MONITOR" | Select InfName

InfName
-------
oem30.inf
oem30.inf

也标记 mklement0 有用的答案。如果您只需要监视器的所有对象数据，您可以这样做。

Clear-Host
(PNPUtil /Enum-Drivers /class Display | 
Select-Object -Skip 2) | 
Select-String -Pattern 'Monitors' -Context 3,4
# Results

根据需要进行挑选，或者，创建并使用自定义对象以相同的方式获取您的属性，然后只需选择即可。例如：

Clear-Host
((PNPUtil /Enum-Drivers /class Display | 
Select-Object -Skip 2) | 
Select-String -Pattern 'Class Name:' -Context 3,4) | 
ForEach {
    [PSCustomObject]@{
        PublishedName = $PSItem.Context.PreContext[0] -replace '.*:\s+'
        OriginalName  = $PSItem.Context.PreContext[1] -replace '.*:\s+'
        ProviderName  = $PSItem.Context.PreContext[2] -replace '.*:\s+'
        ClassName     = ($PSitem | Select-String -Pattern 'Class Name:') -replace '.*:\s+'
        ClassGUID     = $PSItem.Context.PostContext[0] -replace '.*:\s+'
        DriverVersion = $PSItem.Context.PostContext[1] -replace '.*:\s+'
        SignerName    = $PSItem.Context.PostContext[2] -replace '.*:\s+'   
    }
}
# Results
<#
PublishedName : oe...
OriginalName  : amd...
ProviderName  : AMD
ClassName     : Sys...s
ClassGUID     : {4d...
DriverVersion : 02/...

ProviderName  : West...
ClassName     : WD D...
ClassGUID     : {8496e8....

或者表格格式，或者保存到csv。

Clear-Host
((PNPUtil /Enum-Drivers /class Display | 
Select-Object -Skip 2) | 
Select-String -Pattern 'Class Name:' -Context 3,4) | 
ForEach {
    [PSCustomObject]@{
        PublishedName = $PSItem.Context.PreContext[0] -replace '.*:\s+'
        OriginalName  = $PSItem.Context.PreContext[1] -replace '.*:\s+'
        ProviderName  = $PSItem.Context.PreContext[2] -replace '.*:\s+'
        ClassName     = ($PSitem | Select-String -Pattern 'Class Name:') -replace '.*:\s+'
        ClassGUID     = $PSItem.Context.PostContext[0] -replace '.*:\s+'
        DriverVersion = $PSItem.Context.PostContext[1] -replace '.*:\s+'
        SignerName    = $PSItem.Context.PostContext[2] -replace '.*:\s+'
