Scripting with COMAccess 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 instrumentationExtend and discover properties/methods

Update-TypeData Office.Word.Types.ps1xml$fso | Get-Member

Manipulate and format resultsDefine 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

Scripting with WMIPowerShell provides native WMI supportGet-WmiObject

Allows for inspection of WMI namespaceGet-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'"

Scripting with .NETPowerShell provides native access to any .NET classCreate any object

[reflection.assembly]::LoadWithPartialName("System.Windows.Forms")$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

Scripting with XMLPowerShell provides native XML supportNative 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

Scripting with TextInvoke existing tools

Existing command run directly after variables are expanded

Harvest data from existing toolsParse 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 textUse 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
