How do I retrieve the available commands from a module?

Question

To know which PowerShell modules are available on a machine I use the command

Get-Module -ListAvailable

This returns a list with module-type, -name and the exported commands. But the exported commands are always empty and just displaying {}. Why is this not displayed?

Do I have to use another parameter or is there another cmdlet or method to retrieve the available commands?

Solution 1

Exported commands are not available if the module is not loaded. You need to load the module first and then execute Get-Command:

Import-Module -Name <ModuleName>
Get-Command -Module <ModuleName>

Solution 2

Use the parameter -ListAvailable

Get-Module <moduleName> -ListAvailable | % { $_.ExportedCommands.Values }

"<moduleName>" is optional. Omit to show all available modules.
