我正在使用 Powershell v3.0 的 RC 我想知道如何在返回的对象中查询和显示列表（例如结果中的“ExportedCommands”属性Get-Module -ListAvailable）：

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：

  • 您的收藏实际上是什么（在此命令中-您可以使用字典）
  • 你想看到它还是采取行动。

在这种情况下，知道这是一个字典集合，您可以：

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

.. 或者您可以直接使用这些键 - 但您将失去对模块的跟踪。或者你可以反转它：

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

但同样：这只是为了显示数据。如果要对其进行操作， format-* 将无济于事，您应该改用 select （可能带有 -expand 参数）。

OP 帖子中的问题是，默认情况下，PowerShell 仅显示此类型重复组中的前 N ​​个值。因此，对于导出的命令，您只能看到前 4 个（默认为 4 个）。要改变这一点，只需为变量 $FormatEnumerationLimit 设置一个更高的值。并且根据 Format-Table 的能力，您可能还需要在指向 FT 的显式管道上指定 -wrap，如下所示：

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