Some addendum on modules

If you add modules like  PSUserTools from Microsoft you receive some enhanced functionality. You also receive some well conceived script.  After you have imported your modules ('import-module'), you can use a function like that below to list all the exported commands:

function Global:get-module_exports {

[CmdletBinding()]

Param(

[Parameter(Mandatory=$true)]

$ModName

          )

$commands=(get-module $ModName).ExportedCommands

[Array[]]$list=(($commands).Values) | %{$_.Name} | Sort

$list

}
