One of the nice things about the Get-AWSPowerShellVersion cmdlet is the ListServiceVersionInfo switch parameter. It returns properties for the Service (as in the AWS Service offering name), the Noun Prefix, and API Version. Yes, there really are spaces in those last two property names; however, they’ve been fixed in my function. I had been hoping for an easier way to determine the prefixes used in the AWS cmdlets, and here we have it. I actually considered parsing cmdlet names myself, so a huge thanks to AWS, for making sure that wasn’t necessary.

It’s almost as though this should have been its own cmdlet—a get the version cmdlet and a get the noun prefixes cmdlet. Therefore, I’ve wrapped this command and its parameter in a quick and easy-to-use function for my user base. Copy, paste, and try it out; it’s all yours. Super simple.

Function Get-AWSNounPrefix {
<#
.SYNOPSIS
    The function returns the AWS PowerShell cmdlet noun prefixes, along with the corresponding AWS Service.

.DESCRIPTION
    The function returns the AWS PowerShell cmdlet noun prefixes, along with the corresponding AWS Service name. This function utilizes the AWSPowerShell module's Get-AWSPowerShellVersion function.
