Powershell script to check whether SharePoint 2010 Feature is activated for a particular Sub-site

The Powershell script below checks whether any given feature, in this case its the PublishingWeb Feature is activated or not for a particular Sub-Site.


Here I have shown 2 approaches: 1st one checks the Feature Folder Name and 2nd approach checks the FeatureID activated for that particular Sub-site. Choose the way best suitable in your case.


Add-PsSnapin Microsoft.SharePoint.PowerShell


## SharePoint DLL
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")


$featureFolderName = "PublishingWeb"
$subSiteURL = "http://sharepointfix/sites/home/USA"


#Approach 1 - Check using Feature Name
#Get Feature ID based on the Feature Name and ensure whether its already activated or not at the current sub-site scope
$FeatureID = Get-SPFeature -Web $subSiteURL | Where {$_.DisplayName -eq $featureFolderName}


if($FeatureID -ne $null)
     {
      #Approach 2 -  Check using Feature ID
      #Check whether Feature to be activated is already activated for this sub-site
      if (Get-SPFeature -Web  $subSiteURL | Where {$_.ID -eq $FeatureID.Id})
      {
       Write-Host $featureFolderName "is already activated at :" $subSiteURL 
       }
      else
      {
       Enable-SPFeature -Identity $featureFolderName -Confirm:$false -Url $subSiteURL 
       Write-Host $featureFolderName "has been activated at :" $subSiteURL
      }
     }
else
{
      Enable-SPFeature -Identity $featureFolderName -Confirm:$false -Url $subSiteURL 
      Write-Host $featureFolderName "has been activated at :" $subSiteURL 
}
