Question

我正在使用Powershell v3.0的RC 我想知道如何查询和显示返回对象中的列表（如Get-Module -ListAvailable结果中的“ExportedCommands”属性）：

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...

Answer 1

嗯..一切都取决于两个因素：

你的收藏实际上是什么（在这个命令中 - 你可以字典）
你想看它还是行动。

在这种情况下，知道这是一个字典集合，你可以：

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

..或者你可以找到那些钥匙 - 但是你会忘记模块。或者你可以改变它：

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

但同样：这只是显示数据。如果你想对它进行操作，format- *对你没有帮助，你应该使用select（可能是wit -expand参数）。

OP的帖子中的问题是，PowerShell默认只显示此类重复组中的前N个值。因此，对于导出的命令，您只能看到前4个（默认值为4）。要更改此设置，只需将更高的值设置为varible $ FormatEnumerationLimit。根据Format-Table的功能，您可能还需要在显式管道上指定-wrap，如下所示：

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