This is a summary of the session:Administrating SharePoint 2010 with PowerShell held by Zach Rosenfield at the SharePoint 2009 conference.

If you have followed this blog before you know that a little now and then I talk about PowerShell, not as much as my colleague Niklas on powershell.nu but anyway. PowerShell in SharePoint 2010 will be The administration tool to really handle your environment. The strengths of PowerShell is that it can deal with the .net library objects directly, it has performance benefits for batch operations and in 2010, you are able to do it from remote!

The figure on how many commandlets that will be included in SharePoint 2010 is different from each session but I choose to believe PowerShell Guru Zach when he says 652.

This session was one long (but very good) demo on how PowerShell works and what you can do with it. The answer is everything. And improvements done for 2010 is as mentioned the remote interface which makes it possible to do it from your client. The Performance has significantly been improved and one that that I liked very much was the parameter –whatif. That makes it possible to run your command, see the output from it but the command was not actually executed. This makes it possible to try your commands out first and not screw up your environment completely
