Update metadata of MOSS document library item using powershell

Is it possible to update metad开发者_StackOverflowata of an item in SharePoint 2007 document library using powershell?

I'd like to execute a CAML query and then change && update every item in the results list. My goal is to write a single throwaway script instead of writing a console app in VS. Can anyone point me towards a way of doing this?

Thanks, josko

I'm normally able to do anything in sharepoint 2010 just using Powershell and:

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Sharepoint")

But never tried in Sharepoint 2007. However I think you won't have any problem, since it seems Sharepoint Services 3.0 supports the assembly as well, along with SPQuery
