Have you ever heard about PowerShell Accelerators?

It is what makes it easy to handle stuff like XML files, WMI Objects or Active Directory Objects.

We use it for pre-defining variable and calculations types too.


for example we can read a XML file using [xml] and get-content

PS C:\> $xml = [xml] (Get-Content myXMLFile.xml)

by using this method we are able to parse the XML into real PS objects, and therefore we can acess the parts by using the dot net way.

PS C:\> $xml.Config.ServerName


This will read the ServerName Tag inside the Config tag.

Problem is that there is a lot of these, and no official complete list.

One of the reasons is that, new accelerators might become available, when you import modules.

But by using these few lines of code you will get the complete list of available accelerators:

$acceleratorsType = [type]::gettype("System.Management.Automation.TypeAccelerators")
$acceleratorsType::Add("accelerators", $acceleratorsType)

On my windows 7 PC I have the following list (no extra modules is loaded)

As you can see , there is a lot of them!

you can even create your own. Read this blog post

On of the cooler ones is [adsisearcher].

All it need is a AD query as input I you will have the result in the variable.

Actually if you are familiar with .net programming, you know that types in .net is named fx:
