2. Welcome!
We’re here to get you up and running with PowerShell – as quickly as possible.
99% of what you’ll see applies to v2 and v3; we’ll point out some specific v3 coolness as we go
Please ask questions as we go, although we are on a tight schedule, so some stuff we may need to pick up at the end.

3. Quick Introductions Don Jones Jeffrey Snover

Inventor of Windows PowerShell

4. Let’s Begin! PowerShell is a command-line interface (CLI)…
…that contains a rich, yet simplified scripting language for automating complex, multi-step tasks
Built on the .NET Framework
Extensible, so various products and technologies can be managed by “snapping in” tech-specific extensions
Most importantly… it’s discoverable! It can teach you how to use itself!

5. Letting PowerShell Teach You How to Use PowerShell
The Help System, Modules, and More

6. The Pipeline
PowerShell has an extremely powerful pipeline that works unlike anything that’s really been done before
It carries the output of one command to the input of the next… but it does so in an amazingly flexible way
If you can master the pipeline (and the help system helps!)

7. The PowerShell Pipeline
ByValue. ByPropertyName, and ByJoveThatsAmazing

8. Speaking of CIM…
PowerShell remains the most effective way to access Windows Management Instrumentation, which provides a wealth of management information
V2 and v3 both have the “WMI” cmdlets, which utilize the old-school DCOM/RPC protocol for communications
V3 Introduces “CIM” cmdlets, which use the same WMI back-end info repository, but communicate over WS-MAN

9. (And why WS-MAN is your new best friend)
WMI and CIM
(And why WS-MAN is your new best friend)

10. And oh, You WANT WS-MAN!
First, it’s auto-enabled in Windows Server 2012
It’s also the basis for PowerShell’s awesome-est feature, Remoting
We’ll do a quick Remoting demo, but Don has an entire “Remoting in Depth” session that you just gotta check out.

11. PowerShell Remoting and WS-MAN

12. Objects You may have heard that PowerShell is an object-oriented shell
People make a big deal of this because it enables a lot… but conceptually it’s pretty simple
Ever see an Excel spreadsheet? It’s just a data structure, right? Well, that’s all objects are. Data structures, in memory.
Every PowerShell command (well, most) produces objects… and PowerShell will even show you everything about them

13. Object-Oriented Shell
It’s all just data!

14. But You Know…
Not every technology lends itself well to a static set of predefined commands
Take IIS, or SQL Server, or anything else that’s extensible. How do you know what commands admins will need when you don’t even know everything that might be added into the product?
The answer: Providers. PowerShell providers can make any storage – even configuration stores – look like a disk drive. You get to use familiar commands with them!

15. PSProviders and PSDrives
Adapting storage to look like a file system

16. Lots of Smarts
PowerShell includes a full set of comparison operators that, combined with a filtering cmdlet, let you remove things from the pipeline.
It’s what’s left at the end of the pipeline that gets displayed.

17. Comparing and Filtering
Help about_comparison_operators is your friend!

18. Hate Syntax? Yeah, it’s harder than clicking buttons in a GUI.
And in large part you can still use a GUI if you want to, even though it may just be running PowerShell commands under the hood.
But think about where companies are headed… and think about your value to your organization.

19. Would You Rather be a Button Monkey… or a ToolMaker?
If you do something more than once… automate it.
PowerShell finally gives us a way to do that.

20. Become a ToolMaker
Not a Button Monkey!

21. More Fun Tips Why “cmdlet?” Formatting? Make it the last thing you do.
Neat tricks with double quotes.
Why you should avoid Write-Host
