Overview of PowerShell Introduction to PowerShell Scripting

Language Tools Script Authoring SharePoint Management Console SharePoint CmdLets

NYC Code Camp

I will be presenting on LightSwitch and Silverlight at the NYC Code Camp 6 (Autumn 2011)

Saturday October 1st

Interactive Command Shell Programmatic (Script) Execution

Environment Dynamic Scripting Language Extensible (CmdLets, .Net etc…) Hosted (i.e. NuGet) Management tool for Servers

“A shell is the piece of software that lets you access the functionality provided by the operating system. “ Bruce Payette - Co-Designer and Implementer of the PowerShell language. Example

Windows Explorer Command.com Cmd.exe Bash (Unix) PowerShell

Interactive Environment with .Net Automation Tool Easy to use Available on all Windows SKUs starting with

XP SP2 and Windows 2003 Management tool for Servers

Productivity Gains – One Liner

Common Parameters -Verbose -Debug -WarningAction -WarningVariable -ErrorAction -ErrorVariable -OutVariable -OutBuffer

Risk Mitigation Parameters (certainly critical in a production environment)

What-If -Confirm

Wildcard support.

All names and parameter value can support wildcard. Pipeline

Much more about this later.

Command vs. Expression mode parsing Echo 1+1

1+1 Everything returns a value “String”

Variable $ Prefix

i.e. $var = “Hello Sharepoint” Type System All .Net types as well as Custom Types

Help Get-Help (or -? Following any command) Get-Help about_<<anyname>> Get-Help –Examples Get-Help –Full

High level task oriented abstraction Verb-XXNoun Verbs: Get, Set, New, Write, Read

Nouns: Drive, Variable, Provider, Site, Collection Get-Verb Predefined Commands When Starting Remember these: Get-Help

Get-Member

Get-Command

Get-Help As it says, it helps!!!

Get-Command Get information about what can be invoked

Get-Member Show what can be done with an object

Get-Module Show packages of commands

GetType Discover details about an object’s type information.

Out-Host Out-Null Out-Printer Out-String Out-GridView

The best part about PowerShell

Output of one CmdLet is Input into next CmdLet in pipeline.

Uses the Pipe operator |

Output and Input are objects, not text like traditional shells.

Example

▪ Get-Command | Get-Member

▪ Get-Process | Out-GridView

Case-Insensitive Variables: begin with $ (i.e. $a = “test”) Script Blocks using {} Array $a = 1,2,3 $a[1]

Hashtable $h = @{a=1; b=2}

Scope – Functions and Script Blocks Security Context aware Remoting - WSMan

If then else If ($a –eq “test”) { “It’s a test”} else {“Not”}

While loop and Do While loop $i = 1; While ($i –lt 10) {$i++}

$i =5; do {$i} while (--$i) For loop for ($i=0; $i –lt 10; $i++) { “5 * $i is $(5 * $i)” }

Foreach loop Foreach ($i in 1..10) {“`$i is $i”}

Foreach CmdLet

1..10 | ForEach-Object {“begin”} {$_ * 2} {“end”}

Where Cmdlet

1..10 | Where-Object {$_ -gt 4 -and $_ -lt 10}

Arithmetic Operators

+ * - / %

Assignment Operators

=, +=, -=, *=, /=, %=

Get-Location and SetLocation Copy-Item Remove-Item Move-Item Rename-Item Set-Item New-Item Get-Content

Pretty much the same as CMD

> replace file

>> Append to file

2> File is replaced with error messages

2>> Error text is appended to file

2>&1 Error messages are written to output pipe

A module is a package that contains Windows PowerShell commands, such as cmdlets, providers, functions, variables, and aliases

Need to create module folder new-item -type directory -path

$home\Documents\WindowsPowerShell\

Modules

Copy the module to the Modules folder. Start using a module (import-module etc…)

Standard Providers Windows PowerShell providers are Microsoft .NET Framework-based

programs that make the data in a specialized data store available in Windows PowerShell so that you can view and manage it

Get-PSProvider | Select -Property Name WSMan - Alias Environment FileSystem Function Registry Variable Certificate

Get-PSDrive New-PSDrive

New-PSDrive -Name Y -PSProvider FileSystem -Root c:\temp

Remove-PSDrive Remove-PSDrive

Try a non-disk PSDrive like cert: Dir Cert:

A Script file is a text file with .ps1 extension containing one or more PowerShell command

A Script is a simple mechanism to re-use functionality.

To run a script on a remote computer, use the Invoke-Command and provide remote computer name as a parameter.

Scripts can accept parameters. To run a script in the current session, we Dot-

Source the . .\Script1.ps1 We can Scope Local or Global.

Single Line: # Multi Line:

<#

#>

Comments can be used to automatically generate help

A function is a script block containing list of statements

function small_files ($size = 1kB) { Get-ChildItem c:\Temp | where { $_.length -lt $size -and

!$_.PSIsContainer} } small_files

To control how a function uses the pipeline, you use Begin, Process and End.

function pipelineFunc {

process {"The value is: $_"}

}

1,2,3 | pipelineFunc

Advanced functions allow you to write CmdLets using scripts instead of compiled code.

try

{

$wc = new-object System.Net.WebClient

$wc.DownloadFile("http://www.contoso.com/MyDoc.doc","c:\MyDoc.doc")

}

catch [System.Net.WebException],[System.IO.IOException]

{

"unable to download MyDoc.doc from http://www.contoso.com."

}

catch

{

"An error occurred that could not be resolved."

}
