Question: How can I see all of the Help examples for cmdlets from a specific module?

Answer: After you have updated your Help in Windows PowerShell 3.0, use the Get-Command cmdlet to retrieve all cmdlets from a specific module, pipe the results to the Foreach-Object cmdlet, and use the Get-Help cmdlet inside the script block. Following is an example for the PrintManagement module:

Get-Command -Module PrintManagement| Foreach-Object {get-help $_.name -Examples}

Here is a shorter version of the same command:

gcm -mo *print* | % {get-help $_.name -ex}

List PowerShell modules
To obtain a listing of all modules that are available on the system but are not loaded into the Windows PowerShell console, you can use the Get-Module cmdlet with the −ListAvailable parameter, as shown here:

PS C:\> Get-Module –ListAvailable

Does this module support Updatable Help?
Some modules support Updatable Help and others do not. Fortunately, there’s an easy way to tell which modules support Updatable Help.

If the HelpInfoUri property of a command (such as cmdlet, function, CIM command, or workflow) has a value, and the value is valid (that is, it begins with “http” or “https”), the module supports Updatable Help.

PS C:\> Get-Module -ListAvailable | where HelpInfoUri

The HelpInfoUri property of each module object comes from the HelpInfoUri key in the module manifest. Following is the module manifest of the NetQos module, and you can see the HelpInfoUri key:

PS C:\> cat (get-module -list netqos).path
