PowerShell and SharePoint

Windows PowerShellNew command-line shell and scripting language

• As interactive and composable as BASH/KSH

• As programmatic as Perl/Python/Ruby

• As production oriented as AS400 CL/VMS DCL

• Allows access to data stores as easy to access as filesystem

Why powershell ??

Have better solution than standard « cmd.exe » (Evolution of MS-DOS)Replace Perl, KixStart or VBScript scripts, for execute simple tasks

PowerShell :Object OrientedCan use .Net objectsGive many command

Object oriented

In classical environment, command execution results in text

In PowerShell each result is object. We can use also the attributes and methods

Characteristics

.Net powered

Can call WSH, COM, and WMI objects with .Net objects

Many Commandlets

Standard in commands and parameters

PowserShell commands

PowerShell commands named « cmdlets »  (ie: command-applets).

One verb and a name with a dash (-),

Generic verb list(Get, Set, Add, Remove, etc.) with diferent name like Path, Variable, Item, Object etc.

Lot of name possible for commands

Parameters

Diferent solutions for use parametersget-command -Name [string] -Type [CommandTypes] -Verb [string] -Noun [string]

Use “” if parameter have a space or special char

Basic commands

First of all: « Get-Command ».

For help: Get-Help with command.

More help on command: « Get-Help Get-Command –detailed » with some examples « Get-Help Get-Command –full » with all technical informations

Aliases

Command « Short Name» Alias «my_cmd» for the command « very-long-command-to-write».

Help shell Unix or cmd.exe users with their uses …

ls, more, pwd, etc. ls is the command alias for Get-ChildItem which shows the file or folder list.

Variable use

A PowerShell variable is define by the prefix $ with the name and can receive value

We can create the named variable $current-process and store the active process list

$current_process = Get-Process

The Pipe

Action between commands

PowerShell built for transition data between commands without change (more text transform)

Get-Process | where { $_.handlecount -gt 400 } | Format-List

Conditions and operators

Condition in PowerShell, we can use operators If, ElseIf and Else

$current_process = Get-ProcessIf ($current_process.count -lt 50){        Write-Host « Low server load";}Elseif (($current_process.count -ge 50) -and ($current_process.count -lt 80)){        Write-Host « Middle server load";}Else{        Write-Host « High server load";}

Loop use

We can create loop in PowerShell as While, Do While, For or Foreach.

$var = 1 // One variable set to 1while ($var -le 50) {$var; $var += 1} // while the value is not equal to 50, we add 1

for ($var = 1; $var -le 50; $i++) //

{$var} // each steps we show the variable value

Objects use

WMI objectsInclude in PowerShell in standard, no creation needGet-WmiObject –list

.NET and COM objectsCreate a new object for a variablePS C:\> $xls = New-Object -ComObject Excel.ApplicationWe can use the methods and properties

PowerShell V2 Goals

Reduce the cost and effort to:Use PowerShell

Get, learn, share scripts

Layer applications on PowerShellGUI, web, workflow, etc.

Manage anything/everythingServers, clients, distributed systems, applications, web services, cloud services, raw HW, other OSes, everythingUsing any and all mechanisms (WMI, .Net, native code, web services, WSMAN)

Pre-requisites

Microsoft .NET Framework 2.0

Windows PowerShell remoting et background jobs needs WinRM 2.0 CTP3 : Only for Vista SP1 and W2008

Windows PowerShell Integrated Scripting Environment (ISE) and Out-GridView cmdlet needs Microsoft .NET Framework 3.5 SP1
