PowerShell 技能连载 - 免费的 PowerShell 帮助手册

即便是有经验的 PowerShell 用户也会经常忽略 PowerShell 强大的帮助系统，它类似 Linux 中的 man page。您所需要做的只是一次性下载帮助文件。要下载帮助文件，您需要在提升权限的 PowerShell 中运行以下代码：

PS> Update-Help -UICulture en-us -Force

当帮助文件下载完以后，以下是一个很棒的基础列表，展示 PowerShell 语言的几乎所有细节：

PS> Get-Help about* | Select Name, Synopsis

您甚至可疑用这行代码创建您自己的 PowerShell 帮助查看器：

Get-Help about* |
    Select-Object -Property Name, Synopsis |
    Out-GridView -Title 'Select Topic' -OutputMode Multiple |
    ForEach-Object {
    Get-Help -Name $_.Name -ShowWindow
    }

当运行这行代码时，PowerShell 将搜索帮助主题并打开一个网格视图。只需要按住 CTRL 并选择所有您想阅读的主题，然后单击确认。选中的主题将会在独立的帮助查看窗口中打开。
