Getting the commands available in PowerCLI
Nouns and Verbs

Example of all the commands:
Get-VIcommand

Get-VICommand notice the heading command type - name - definition

Name is the commandlet (lots)

Get-Vicommand | Measure-Object = show you the total number of commandlets in PowerCLI

****You can sort by Groups to view them verb
the verb is the verb before the dash -  wait-|task  = verb is "wait"

Could sort by count = Get-Vicommand | Group-Object verb | Sort count

or even group by noun
