使用 PowerShell 在 SharePoint 中的所有网站集上激活/停用功能

我们在 SharePoint 2013 中使用“Enable-SPFeature”和“Disable-SPFeature”PowerShell cmdlet/SharePoint 2016 网站激活或停用功能，如我的另一篇文章：如何激活-停用 SharePoint 中的功能。有时，我们可能必须激活所有网站集的功能或停用所有网站上的功能。这是我的 PowerShell 脚本来执行此操作。

为 SharePoint 中的所有网站集启用一项功能：

就我而言，由于许可限制，我必须在 Web 应用程序下的每个网站集中启用“在客户端应用程序中打开文档”功能，以强制在 Office 客户端（例如 Microsoft Word）而不是 Office Web 应用程序中打开文档。

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue

#variables
#$WebAppURL = "https://intranet.crescent.com"
$FeatureName ="OpenInClient"

#Get the Web Application
$webApp = Get-SPWebApplication -Identity $WebAppURL

#Get all site collections with in the web app
$SitesCollection = $WebApp | Get-SPSite -limit all 

#Iterate through each site 
foreach ($site in $SitesCollection)
{
    #Check if feature is already activated
    $feature = Get-SPFeature -site $site.Url  | Where-object {$_.DisplayName -eq $FeatureName}
    if($feature -eq $null)
    {    
        #Enable the feature 
        Enable-SPFeature -Identity $FeatureName -url $site.url -Confirm:$False
  
        Write-host "Feature Activated on $($site.URL)" -ForegroundColor Green    
    }
    else
    {
        Write-host "Feature is already Active on $($site.URL)" -ForegroundColor Red
    }
}

PowerShell 停用所有站点上的功能：

要求：在 SharePoint 2013 Web 应用程序的所有网站上停用“移动重定向”功能。
