Finding Features Packed in SharePoint Solution

Features

A Feature is a container of various defined extensions for SharePoint Server 2010 and is composed of a set of XML files that are deployed to front-end Web servers and application servers. You can deploy a Feature as part of a solution package and you can individually activate a Feature in SharePoint Server sites.

Features are packages of functionality that you can activate and deactivate in a SharePoint Farm. They have the following four possible scopes.

Farm: A Farm level feature, as the name suggests, is something that affects the entire Farm.

Web Application: A web application feature can be activated so that it only affects a single web application and a typical example is a feature that modifies the web.config file.

Site: A site scoped feature can be activated so that it only affects a site collection, an example being the deployment of a master page to the master pages catalogue.

Web: Finally, a web scoped feature can be activated for a single site, for instance setting the default master page for that site.

Features make it easier to activate or deactivate functionality in the course of a deployment and administrators can easily transform the template or definition of a site by turning on or turning off a specific Feature in the user interface.

Feature packed in SP solution

The following piece of code finds the feature packed in given solution:

$solution = ""

[string]$solution = Read-Host "Enter the Solution name: [e.g. MyCustomSolution.wsp]"

try {
    Write-Verbose "Getting solution features ..."

    $features = @()

    $solution1 = Get-SPSolution -Identity $solution -ErrorAction SilentlyContinue

    foreach ($grp in Get-SPFeature | where {$_.SolutionID -eq $solution1.id} | Group-Object SolutionId) {
    foreach ($fd in $grp.Group | sort DisplayName ) {
        $feature = New-Object -TypeName PSObject -Property @{
        SolutionName = $solution1.Name
        SolutionId = $solution1.Id
        FeatureName = $fd.DisplayName
        FeatureId = $fd.Id
        FeatureScope = $fd.Scope
        }
        $features += $feature
        }
        }
        Write-Output $features

      }
catch [Exception] {
    Write-Error $Error[0]
    $err = $_.Exception
    while ( $err.InnerException ) {
        $err = $err.InnerException
        Write-Output $err.Message
        }
      }
