Moss 2007 StsAdm Reference Poster by Microsoft
All SharePoint developers and administrators will be familiar with the Stsadm.exe command line tool in the bin folder of the "12 hive", normally located at: C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN\STSADM.EXE. This tool has many available operations and an extensibility model. For a nice poster on all available operations (Moss2007 SP1) and available properties, see http://go.microsoft.com/fwlink/?LinkId=120150.
Although Stsadm is a nice mechanism for managing SharePoint, we really need a PowerShell interface to do all these same operations. There are already some first small PowerShell libraries available, and also Gary Lapointe is starting a PowerShell library. See this blog post for his first steps in this direction.
