13. How can I script with Windows PowerShell? Script against various: Instrumentation: Text, COM, .NET, Cmdlets Object types: WMI, XML, ADO, ADSI Datastores: Filesystem, Registry, Certs, etc Ad-hoc scripts need to be quick and easy Arguments don’t need to be named or typed Scripts don’t need to be signed Production scripts need be to production quality Arguments can be typed, named and have initializers Rich error handling Protection from uninitialized variables Data can be written to multiple streams Output, Error, Debug, Verbose, Warning, Progress Scripts can be digitally signed

14. Simple Scripting Arguments not declared or typed function MyEcho { for ($i = 0; $i –lt $args.count; $i++) { “arg{0} = {1}” –f $i, $args[$i] } }

15. Advanced Scripting function Get-Total ( [String]$property = $(throw "Property Required"), [string]$formatString = "Total {1} = {0}" ) { Begin { $total = 0 } Process { $total += $_.$property } End { $formatString -f $total,$property } } Arguments declared, typed, initialized

16. Sophisticated Scripting function Get-Types ( [ScriptBlock]$AssemblyFilter = {1}, [ScriptBlock]$TypeFilter = {$_.IsPublic –eq “TRUE”} ) { TRAP [System.Exception] {Write-Error “ERROR: $_.Exception”} foreach ($a in [AppDomain]::CurrentDomain.GetAssemblies() | where $AssemblyFilter) { $a.GetTypes() | where $TypeFilter } } • Uses .NET APIs, traps, ScriptBlocks
