4. A modern replacement for the CMD (command) shell

5. PowerShell works with objects

6. PowerShell integrates with the .Net Framework

7. PowerShell is based on a provider-based model

10. Pipelining allow one Cmdlet to return an object as input to anotherC#: X = Class.Method(); Y = OtherClass.Method(X); Z = OtherOtherClass.Method(Y) PowerShell: Class.Method() | OtherClass.Method() | OtherOtherClass.Method()

12. PowerShell vs STSADM

13. PowerShell vs STSADM - Performance Performance benefits for batch operations STSADM Batch Operation PowerShell Cmdlets in Batch Start Thread New STSADM Execution Start Thread Load DLLs Start logging Repeat Start Logging Execute Command Repeat Execute Command Stop logging Stop Logging Stop Thread Close STSADM & Thread

14. PowerShell vs STSADM - Performance PowerShell “Wrapped” STSADM to enable a feature on every SPSite Same command in SharePoint 2010 PowerShell: $rawdata = stsadm.exe -o enumsites -url $WebAppURL $sitexml = [XML]$rawdata $sitesxml.Sites | foreach-object{ $_.Site } | foreach-object{ stsadm -o activatefeature -url$_.url -filename $featureFileName if( $lastexitcode -ne 0 ){ Write-Host “Failure:$lastexitcode " -Fore Red; $failure = $true; } } 12+ Hours (5300 SPSites) 30 Minutes (5300 SPSites) Get-SPSite –Limit ALL –WebApplication $WebAppNameorUrl |%{ Enable-SPFeature$FeatureIdOrName –url $_.Url }

17. Getting Started with PowerShell (1) Execute a Cmdlet (2) Filter results using where clause (3) Add formatting instructions (4) Redirect output to new text file

18. Getting Help in PowerShell

19. Controlling PowerShell with variables, loops, logic, and functions

20. Variables in PowerShell A variable is a place for you to store some value so you can revisit it later. All variables that you create begin with $ Ex: $my_first_variable= “Hello World” Variables Types Loosely typed variables $f = “bar” #implicitly typed as string $ary= 4,2,5,2 #typed as object[] Strongly typed variables [string]$f = “bar” Enhanced Types variables [xml]$d = “<a><b><c>c stuff 1</c><c>c stuff 2</c></b></a>”

21. Looping in PowerShell Classic PowerShell Loop - For Loop $i = 10 For($j = 1; $j-lt $i; $j++){ Write-Host ”$j”; } - ForeachLoop $NumArray= (1,2,3,4,5,6,7,8,9,10)Foreach($Item in $NumArray) {$Item * 3} - While Loop $i =8 While ($i-le 96) { $i+=8; Write-Host$i; } - Do Until Loop $i = 7; do { $i+=7; Write-Host$i; } until ($i-gt 85) ForeachLoop with Pipeline Get-SPSite -Limit All | foreach { Remove-SPSite -identity $_.Id } $_ and is a variable that represents the current object

22. Adding logic in PowerShell Logic is what enables you to do something at a specific point in the program. Statements If/ ElseIf/ Else Switch While Comparison Operators -eq/-ne -lt / -gt -le / -ge -like / -notlike -contains/-notcontains -replace …

23. Working with PowerShell functions FunctionListRootDrive($DriveLetter) { Get-ChildItem–Path $DriveLetter} Function ListRootDrive { Get-ChildItem–Path $Args} FunctionListRootDrive { Get-ChildItem–Path $Args[0] } FunctionBlogUsers($SiteCollection) { Get-SPWeb-Site $SiteCollection| ForEach-Object { Write-Host “Site Title: “ $_.Title if ( $_.Title -eq “Blog” ) { Write-Host “Blog Users:” $_.Users }}}

25. Foreach-Object ~ %

26. Get-ChildItem|foreach-object { $_.Name }

27. Alias: dir|% { $_.Name }

28. Where-Object ~ ?

29. Get-ChildItem|where-object{$_.Length –gt10}

30. Alias: dir|?{$_.Length –gt10}You can find these aliases with the Get-Aliascmdlet

31. Creating your own PowerShell scripts

32. Tools Notepad PowerShell Command Windows PowerShell Integrated Scripting Environment (ISE) PowerGUI - Download from powergui.org

33. How to Create and Run a PowerShell Script The steps to create a script follow: Create the script in Notepad and save with a .PS1 file extension (hello.ps1). Run the script by entering the full path to the script (c:criptsello.ps1), or if it’s in the current directory (.ello.ps1). If the path to the script contains a space, enclose the full path in quotation marks and prefix the entire thing with an ampersand ("C:y scriptsello.ps1").

34. Scripts and Execution Policy Local execution policy must be configured Scripts will not execute under default execution policy of restricted Scripts can execute under execution policy of unrestricted. Scripts that are not signed result in prompting user for permission to execute. Scripts can execute under execution policy of bypass. This mode suppresses prompting user for permission to execute.

35. Editing Scripts using PowerShell ISE Supports Color-coding, IntelliSense and debugging Writing scripts here Run cmdlets or functions here Results

36. Examples of SharePoint Scripting

37. The SharePoint PowerShell Snapin Explicitly load SharePoint PowerShell snap-in from console or script Implicitly load SharePoint PowerShell snap-in by using SharePoint 2010 Management Shell Begin using SharePoint Cmdlets

38. Scheduling Your Scripts Sometimes commands need to be scheduled to run automatically PowerShell Scripts (.ps1) can be scheduled using Task Scheduler Just put the above command into a .bat or .cmd file and schedule it like you would normally schedule a script to be run with Task Scheduler.

39. Demo – Series Of Scripts Run hello.ps1 script How to use PowerShell to create sites. How to use PowerShell to populate items in a List for testing, adding attachments How to use PowerShell to copy items from one list to another. How to use PowerShell to upload documents to a document libraries. How to use PowerShell to backup sites.
