Agenda
• Introduction to PowerShell• Why PowerShell for SharePoint?• When use PowerShell?• PowerShell vs STSADM• Getting started with PowerShell• Controlling PowerShell with variables, loops,
logic, and functions• Creating your own PowerShell scripts • Scheduling your PowerShell scripts• Demo• Q&A
Introduction to PowerShell
• What is Shell?Working with a command-line interface, often called a shell
• What is PowerShell? A modern replacement for the CMD (command)
shell PowerShell works with objects PowerShell integrates with the .Net Framework PowerShell is based on a provider-based model
A powerful scripting environment for administration
PowerShell Fundamentals
• Scripts– PowerShell code in a PS1 (similar to .bat files)
• CmdLets– A PowerShell command is called CmdLets– Like Features in SharePoint, performs a task– Can be compiled or in script
Ex: Get-Process and Stop-Process
• Snapins– Like Solutions in SharePoint, they hold a lot CmdLet– Compiled into dlls
Ex: Microsoft.SharePoint.Powershell
• Pipelining • Formatting features• Provider-based model for accessing resources
The Pipeline
• What is Pipeline?The most unique feature of PowerShellPipelining allow one Cmdlet to return an object as
input to another
• C#: – X = Class.Method();– Y = OtherClass.Method(X);– Z = OtherOtherClass.Method(Y)
• PowerShell:– Class.Method() | OtherClass.Method() |
OtherOtherClass.Method()
Why PowerShell for SharePoint 2010?
• Automated build and deploy• Rapid prototyping• Remoting interface• Administration automation• Easy for controlling, manipulating and
modifying our SharePoint environment• PowerShell support effectively replaces
STSADMSTSADM.EXE
We’ll miss you old friend
PowerShell vs STSADM
STSADM is SharePoint-specific command interface
PowerShell is a generic scripting interface
Extensible with compiled code only Extensible via script interface into .Net objects
Limited scripting using VBScript/JavaScript Cmd
Is an extensible scripting environment
Output is basic text or Xml Output is rich objects to a pipeline
STSADM does not allow you to access file system, registry and so on
PowerShell gives you access to the file system, registry, data source…
STSADM in MOSS 2007 support 182 Commands
PowerShell in SharePoint 2010 support 652 cmdlets +
PowerShell vs STSADM - Performance
• Performance benefits for batch operations

New STSADM Execution
Start Logging
Execute Command
Load DLLs
Stop Logging
Close STSADM & Thread

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 \n" -Fore Red; $failure = $true; }}
Get-SPSite –Limit ALL –WebApplication $WebAppNameorUrl |%{ Enable-SPFeature $FeatureIdOrName –url $_.Url }
12+ Hours(5300 SPSites)
30 Minutes(5300 SPSites)
When use PowerShell?
• When you want to make your team more agile- Automation, automation, automation
• Development phase - Using PowerShell to save time for Build/Deploy/Test Cycle
• Testing phase– Using the PowerShell scripts to stand up an environment
for running tests

Who should learn PowerShell?
• SharePoint Admins/Devs should learn PowerShell basics
• Why you should learn PowerShell?
1. Microsoft says it’s important2. You can’t do everything from the GUI any more3. It can make your life easier4. Most Microsoft products will eventually use it5. Microsoft certification exams contain PowerShell
questions6. Improve your job7. It’s not going away anytime soon
Getting Started with PowerShell
(4) Redirect output to new text file
(2) Filter results using where clause
(1) Execute a Cmdlet
(3) Add formatting instructions
Getting Help in PowerShell
Controlling PowerShell with variables, loops, logic, and functions
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 TypesLoosely 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>”
Looping in PowerShell
• Classic PowerShell Loop- For Loop
$i = 10 For($j = 1; $j -lt $i; $j++){ Write-Host ”$j”; }
- Foreach Loop$NumArray = (1,2,3,4,5,6,7,8,9,10)Foreach ($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)
• Foreach Loop with PipelineGet-SPSite -Limit All | foreach { Remove-SPSite -identity $_.Id }$_ and is a variable that represents the current object
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– …
Working with PowerShell functions
• Function ListRootDrive($DriveLetter){ Get-ChildItem –Path $DriveLetter }
• Function ListRootDrive{ Get-ChildItem –Path $Args }
• Function ListRootDrive{ Get-ChildItem –Path $Args[0] }Function BlogUsers($SiteCollection) {Get-SPWeb -Site $SiteCollection | ForEach-
Object { Write-Host “Site Title: “ $_.Titleif ( $_.Title -eq “Blog” ) { Write-Host “Blog
Users:” $_.Users}}}
PowerShell Aliases
PowerShell commands are usually long. However, PowerShell has aliases. You can use aliases to save yourself the time and effort of typing cmdlets
Get-ChildItem ~ dir Foreach-Object ~ %
Get-ChildItem | foreach-object { $_.Name } Alias: dir | % { $_.Name }
Where-Object ~ ? Get-ChildItem | where-object {$_.Length –gt 10} Alias: dir | ? {$_.Length –gt 10}
You can find these aliases with the Get-Alias cmdlet
Creating your own PowerShell scripts
Tools
1. Notepad2. PowerShell Command3. Windows PowerShell Integrated
Scripting Environment (ISE)4. PowerGUI
- Download from powergui.org
How to Create and Run a PowerShell Script
The steps to create a script follow:1. Create the script in Notepad and save
with a .PS1 file extension (hello.ps1).2. Run the script by entering the full path to
the script (c:\scripts\hello.ps1), or if it’s in the current directory (.\hello.ps1).
3. 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:\my scripts\hello.ps1").
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.
Editing Scripts using PowerShell ISE
• Supports Color-coding, IntelliSense and debugging

Run cmdlets or functions here

Examples of SharePoint Scripting
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
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.
PowerShell -command “c:\PowerShellScripts\BackupSPSite.ps1”
