PowerShell Powershell Modules Module Member Visibility
Example
By default, only functions defined in a module are visible outside of the module. In other words, if you define variables and aliases in a module, they won't be available except in the module's code.
To override this behavior, you can use the Export-ModuleMember cmdlet. It has parameters called -Function, -Variable, and -Alias which allow you to specify exactly which members are exported.
It is important to note that if you use Export-ModuleMember, only the items you specify will be visible.
