What's the proper PowerShell verb/pattern for get-or-create?

Question

I want to create a few PowerShell functions that create an item, or return existing item if it is already there. E.g. database login, folder, etc.

What is a proper verb for this? There is no Ensure in Approved Verbs, and I am not sure what else would be applicable. I considered New-X -IfExists ReturnExisting but I would prefer to follow a common pattern instead of inventing my own.

Are there any built-in PowerShell commandlets that do get-or-create so that I can copy the approach?

Answer 1

Per the approved verb listing:

New vs. Set
The New verb is used to create a new resource. The Set verb is used to modify an existing resource, optionally creating the resource if it does not exist, such as the Set-Variable cmdlet.
