查询子集

我使用PowerShell的3.0 的RC我想知道如何在返回的对象（在Get-Module -ListAvailable结果像“ExportedCommands”属性）查询和显示列表：查询子集

PS H:\> get-module -ListAvailable 


    Directory: C:\Windows\system32\WindowsPowerShell\v1.0\Modules 


ModuleType Name        ExportedCommands 
---------- ----        ---------------- 
Manifest AppLocker       {Set-AppLockerPolicy, Get-AppLockerPolicy, Test-AppLockerPolicy, Get-... 
Manifest BitsTransfer      {Add-BitsFile, Remove-BitsTransfer, Complete-BitsTransfer, Get-BitsTr... 
Manifest CimCmdlets       {Get-CimAssociatedInstance, Get-CimClass, Get-CimInstance, Get-CimSes...

嗯..这一切都取决于两个因素：

什么你的收集实际上是（在这种命令 - 你可以字典）
你想看到它或行事就可以了。

在这种情况下，知道这是一本字典收藏，您可以：

Get-Module -ListAvailable | 
    Format-List Name, @{ 
     Name = 'ExportedCommands' 
     Expression = { 
      $_.ExportedCommands.Keys -join "`n" 
     } 
    }

..或者你可以得到这些钥匙 - 但比你将会失去跟踪模块。或者你可以扭转这种局面：

Get-Command | Sort Module | Format-Table Name -GroupBy Module

但再次：这仅仅是显示数据。如果你想对它进行操作，format- *不会帮助你，你应该使用select（可能是wit -expand参数）。

OP的帖子中的问题是，默认情况下，PowerShell仅显示重复此类型的组中的前N个值。因此，对于导出的命令，您只能看到前4个（默认值为4）。要改变这一点，只需为变量$ FormatEnumerationLimit设置一个更高的值即可。并根据格式，表格的能力，你可能还需要指定-wrap上明确管FT，如下所示：

PSH [C:\foo]: $FormatEnumerationLimit = 99 
PSH [C:\foo]: get-module -ListAvailable | ft -wrap
