In order to master SharePoint 2010, you will have to get comfortable utilizing PowerShell (aka SharePoint 2010 Management Shell). There are so many commands (or command-lets as they are called) that interact with SharePoint that it makes it nearly impossible to remember them all. Use this PowerShell command to output a list of all cmdlets that are found within the SharePoint 2010 namespace:
Get-Command –PSSnapin “Microsoft.SharePoint.PowerShell” | format-table name > C:\SP2010_PowerShell_Commands.txt
If you would like a little more detail, then try this one:
Get-Command –PSSnapin “Microsoft.SharePoint.PowerShell” | select name, definition | format-list > C:\SP2010_PowerShell_Commands.txt
Note: You may also type gcm as the alias for Get-Command.
