What is PowerShell?
V2 Community Technology Preview (CTP)
Learning PowerShell
Automating with PowerShell
Windows PowerShell
New 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
The Difference is OBJECTS!
Get-Process | Where { $_.handles –gt 500 } | Sort handles | Format-Table

Access existing instrumentation
Bind to COM objects
$fso = New-Object -ComObject Scripting.FileSystemObject
$m = [System.Runtime.InteropServices.Marshal]
$word = $m::GetActiveObject("Word.Application")
Invoke methods/access properties
$fso.GetDrive(“C:”)
$fso.VolumeName = “System Drive”
Understand/extend instrumentation
Extend and discover properties/methods
Update-TypeData Office.Word.Types.ps1xml
$fso | Get-Member
Manipulate and format results
Define and import custom formating
Update-FormatData Office.Word.Format.ps1xml
$word.RecentFiles | Sort name | Format-Table
Allows more simpler/more powerful COM scripts because of
utilities and formatting
PowerShell provides native WMI support
Get-WmiObject
Allows for inspection of WMI namespace
Get-WmiObject –list [-Namespace xx]
Get-WmiObject –Class xx –Namespace xx –Property xxx – Filter xxx –
ComputerName xxx –Credential xxx
Native language support
[WMI] “\\JPSDESK10\root\cimv2:Win32_Process.Handle="0“
[WMICLASS] "ROOT\cimv2:WIN32_PROCESS"
[WMISEARCHER]"select * from Win32_process WHERE Name = 'calc.exe'"
PowerShell provides native access to any .NET class
Create any object
[reflection.assembly]::LoadWithPartialName("System.Windows.Fo
rms")
$d = New-Object System.DateTime 2006,12,25
Access Properties/Invoke Methods
$d.DayOfWeek
$d.AddDays(-30)
Access Statics
[DateTime]::Now
[DateTime]::IsLeapYear(2006)
Allows admins to easily access and leverage a huge API set because
of scriptability, utilities and formatting
PowerShell provides native XML support
Native datatype
$x=[xml]"<a><b><c>TEST</c></b></a>“
$b =[xml](type c:\i386\mssecure.xml)
Native syntax to access “data” view of properties
$b.BulletinDataStore.Bulletins.Bulletin[0]
Access to XML methods
$b.BulletinDataStore.SelectNodes(“//Patch”)
XML properties available through PSBase property
$b.BulletinDataStore.PSBase.innerXml
Invoke existing tools
Existing command run directly after variables are expanded
Harvest data from existing tools
Parse output into variables using text utilities.
Pipe data to SELECT and use –FIRST and –LAST
Select-String <REGEX> <Path>
Dir | Select-String <REGEX>
[DateTime]”12/25/2006 7:00”
([DateTime]”12/25/2006 7:00”).AddDays(-30)
Use functions/scripts to wrap the commands and convert output to objects or
provide standard syntax
Safely process text
Use CLR types via Windows PowerShell to safely parse text
[URI]” http://blogs.msdn.com/powershell/archive/2006/04/25/583234.aspx”
Allows admins to get 2-10x more power out of existing commands
because of scriptability
