Activating Feature in Web, SiteCollection, WebApplication Scopes using PowerShell in SharePoint 2013

In this article, let us see how to make a generic script, which has the capability to activate the feature in three scopes. In the previous article, we saw only with the SiteCollection and WebApplication. I thought of making it a more generic and will be helpful across all the projects.

Now the CSV will be looks like below.

Based on the Scope column, the next column needs to be filled.

i.e., if the Scope is Site, then Give the SiteCollectionURL etc.,

Now, the script :-

 $LogTime = Get-Date -Format yyyy-MM-dd_hh-mm
 $LogFile = ".FeatureActivation-$LogTime.rtf"
 
 
 cls
