Specifies the module members that are exported. The Export-ModuleMember cmdlet specifies the module members that are exported from a script module (.psm1) file, or from a dynamic module created by using the New-Module cmdlet. Module members include cmdlets, functions, variables, and aliases. This cmdlet can be used only in a script module file or a dynamic module. If a script module does not include an Export-ModuleMember command, the functions and aliases in the script module are exported, but the variables are not. When a script module includes Export-ModuleMember commands, only the members specified in the Export-ModuleMember commands are exported. You can also use Export-ModuleMember to suppress or export members that the script module imports from other modules. An Export-ModuleMember command is optional, but it is a best practice. Even if the command confirms the default values, it demonstrates the intention of the module author.
