I wrote a PowerShell module recently as part of an update to a service we provide to customers. I needed to dump out all of the comments so they could be submitted for review. I wanted to ignore comment based help sections.
Here's how I did it with the aid of RegEx...
$a = gc "X:\Dev\Modules\BOOM\BOOM.psm1" $a | select-string -Pattern "^\s*#[^#>]"
The same technique could be used to check another module, a lengthy script or a detailed advanced function. Have fun!
