15. Things to know: Permissions

Use Add-SPShellAdmin to give a user above permissions

16. Things to know: Object Disposal
Some cmdlets return huge objects and take up large amount of memory
Objects get disposed at the end of pipeline
Not true for objects stored in a variable
Use a built-in cmdlet as far as possible
Get-SPWeb Identity http://sp2010demo | Set-SPWeb Description This is my demo site

17. Things to know: Object Disposal
Use Dispose() when not using built-in cmdlets
SharePoint 2010 provides cmdlets to workaround this
Start-SpAssignment
Stop-SPAssignment
Objects get associated to an assignment store and get disposed when Stop-Assignment is called

18. Things to know: Execution Policy
By default, PowerShell does not allow scripts to run
Change policy with Set-ExecutionPoilicy
Policy Settings
Restricted (default) scripts will not execute
Unrestricted scripts can execute. Unsigned scripts will prompt user to execute
Bypass (developer mode) scripts can execute, no user prompting to execute
