Summary: Learn how to find Windows PowerShell cmdlets that accept an array of strings for parameter input.  How can I find all the Windows PowerShell cmdlets that accept an array of strings for parameter input?

 Import all modules, then use the Get-Command cmdlet and the ParameterName parameter to look for [string[]] (if you use aliases, the first command shortens to gmo -l | ipmo):

Get-Module –list | import-Module

Get-Command –ParameterType [string[]]

The following script counts parameter types—first it counts arrays of strings, then it counts strings (gcm is an alias for Get-Command):
