Remoting

PSSession

Functions Functions is a script block containing list of statements function small_files ($size = 100MB) {

Get-ChildItem c:\ | where { $_.length -lt $size -and

!$_.PSIsContainer}

}

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

function pipelineFunction {

process {"The value is: $_"}

}

1,2,3 | pipelineFunction

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

Scripts 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.

Error Handling Terminating vs. Nonterminating Errors

Trap

Throw – Sometime useful for parameters

function hi ($name=$(throw '$name is required')) {"Hi $name"}

Errors Handling – as in C# try { $wc = new-object System.Net.WebClient $wc.DownloadFile("http://www.contoso.com/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." }

Snapins, Providers and Drives Get-PSProvider | Format-List Name, PSSnapin

Get-PSSnapin

Get-PSProvider

Get-PSDrive

PowerShell Modules Get-Module –ListAvailable

Import-Module ActiveDirectory

SharePoint Management Shell SharePoint Management Shell differs slightly from

the Standard PowerShell:

Runspace Threading $Host.Runspace.ThreadOptions = "ReuseThread“

SharePoint Specific Snap-In Add-PSSnapin Microsoft.SharePoint.PowerShell

Threading & Proper Object Disposal $Host.Runspace.ThreadOptions = "ReuseThread"

Get-SPAssignment –Global

$spWeb = Get-SPWeb -Identity $url

$spWeb.TreeViewEnabled = $True

$spWeb.Update()

Stop-SPAssignment –Global
