[UPDATE] See this blog post for up to date SharePoint 2010 PowerShell Reference.
SharePoint has for a long time been a notable absentee at the PowerShell party – but it looks like the wait is now almost over. Technical Preview of the product shared by Microsoft just a few days ago has at least a few cmdlets shipped with it.
To deploy a Feature by using Windows PowerShell, you install it and then enable it by using the following commands.
Enable-SPFeature FeatureId -Url http://server/site/subsite
Judging by these examples, nouns in cmdlets are pre-fixed with “SP” to avoid possible naming conflicts.
I’ll keep you posted on any new developments and public information on PowerShell in SharePoint 2010.
For now, it looks like this is a huge step forward by the SharePoint team making the new version much more manageable. Awesome news and great work!
