Agenda


• Do as I say not as I do

• Ask questions

• Be patient!

• Pray to the demo & Cloud gods

Rules for today


•It isn't:– Fire and forget– A packaged executable – Developer-centric– Too hard for an ITPro

•It is:– Command line environment– Microsoft technology holistic– A swiss army knife with a chain saw– The future of ITPro's world

What is it?


• Windows PowerShell is Microsoft's task automation framework, consisting of a command-line shell and associated scripting language built on .NET Framework. PowerShell provides full access to COM and WMI, enabling administrators to perform administrative tasks on both local and remote Windows systems.

– Definition from Wikipedia

• What is it really– PowerShell is an object-based, not text-based, command-line interface for Microsoft

Technologies

• What does that mean:

–Results in PowerShell can be acted upon, not just read from

• Started internally at Microsoft in 2002• Demo'ed at PDC in 2003 - early stage• Private beta• Public Beta in June 2005• April 2006 changed the name to PowerShell• PowerShell v1 for RTW on Nov 14 2006• PowerShell v2 was released in Aug 2009 as a part of Win7 & Server 2008 R2• PowerShell v3 was released as a part of Win8 & Server 2012• PowerShell v4 is coming as a part of Server 2012 R2

History


• Why did Microsoft create PowerShell & move more to a PowerShell world than a GUI world?

• What is it used for:– Deployment

– Configuration

– Management

– Administration

– Development

The Why


•The "hardware"• PowerShell Console vs PowerShell ISE

•The terminology

• Shell• Command-lets - "cmdlets"• Variables• Pipeline• Scripts• Functions• Modules

The Basics


• Main building block of PowerShell• Mini Commands that perform one action• Actually .NET Classes that can easily be created if new functionality is required• The output of one cmdlet can be piped into further cmdlets • Equality test with expressions such as –eq –lt –match

cmdlets


• Script

– A script module is a file (.psm1) that contains any valid Windows PowerShell code.

• Binary

– A binary module is a .NET Framework assembly (.dll) that contains compiled code.

• Manifest

– A module manifest is a Windows PowerShell data file (.psd1) that describes the contents of a module and determines how a module is processed.

• Dynamic

– A dynamic module is a module that does not persist to disk.

• created using New-Module, intended to be short-lived and cannot be accessed by Get-Module

12

Modules


• Instances of classes•Have properties and methods

13

Objects


•Properties and Methods of an object– Properties – what an object is

– Methods – what you can do with the object

14

Members


•Chain of object processing•Output becomes input

15

PipeLine


•Get-verb– Gets approved Windows PowerShell verbs

•Get-member– Listing the Properties and Methods of a Command or Object

• •Get-history

– If you didn’t start transcript, you can still review your history before closing your Shell or ISE window

Functional Explanation


•Use variables•Only one thing at a time•Comment your scripts•Create scripts using an ISE\IDE, execute in shell•Dispose of your objects \ code•Test before using in Production•Write re-usable scripts

The Do’s


• Vary your variables• Hard code your scripts• Take code from the internet or vendor & just RUN in your environment• Assume that code is not harmful… it is.• Run your code in an IDE\ISE and expect everything to work

The Do Not’s


• Comment

– #

• Add

– +

• Equal

– =

– -eq

• Not Equal

– !

– -ne

– -not

19

PowerShell Syntax


• ()– Curved brackets (Parenthesis) are used for required options, compulsory arguments, or control structures

• {}– Curly brackets are used for block expression within a command block

– Used to open a code block

• []– Square Brackets are used to denote optional elements or parameters

– Also used for math functions

Simple Hard Demos


• Why Run-As Administrator

• How to configure icon settings

22

Run-as Administrator


• Using PowerShell to add a server to a farm

• Writing your own scripts using functions

23

Add-Server2Farm

PowerShell vs PowerShell ISE


• PowerShell vs PowerShell ISE

• Methods– Start-transcript

– PowerShell Profiles

Transcription


Creation script– New folders

– New files • .ps1

• .bat

– Adds content to files

– Adds shortcut to the All Users Startup folder
