PowerShell Commands To List SharePoint Features

The more I work with SharePoint 2010 the more I am starting to love PowerShell. My scripting skills are pretty basic (!) but here are a couple of useful little snippets to get back some information from a site that previously I would have spent a while going through the UI or SharePoint Root – mainly as a reminder for myself!

List all installed features on the farm
It’s really straight forward using the Get-SPFeature command to return all installed features. To provide a little more readability to the output it can be sorted as follows:
By feature display name alphabetically,

1
Get-SPFeature | Sort -Property DisplayName

By feature ID,

1
Get-SPFeature | Sort -Property Id

By feature display name alphabetically and grouped by scope,

1
Get-SPFeature | Sort -Property Scope,DisplayName | FT -GroupBy Scope DisplayName,Id

And to write this to a file to allow for viewing in Notepad, Excel etc,

1
Get-SPFeature | Sort -Property Scope,DisplayName | FT -GroupBy Scope DisplayName,Id > c:\AllInstalledFeatures.txt

List all activated site scoped features
Especially in the case of hidden features it’s sometimes necessary to track down if a feature is active on a site collection. Here’s a quick way of seeing which features are activated for an SPSite:

1
Get-SPFeature -Site http://sitecollectionurl | Sort DisplayName | FT DisplayName,Id

List all activated web scoped features
And only slightly modified from the Get-Help Get-SPFeature -examples text, here is a command to list all web activated featres for a site collection:

1
Get-SPSite http://sitecollectionurl | Get-SPWeb -Limit ALL | %{ Get-SPFeature -Web $_ } | SortDisplayName -Unique | FT DisplayName,Id
