Removes modules from the current session.

Syntax

Description

The Remove-Module cmdlet removes the members of a module, such as cmdlets and functions, from the current session.

Description
-----------
This command removes the FileTransfer and PSDiagnostics modules from the current session.

The command uses a pipeline operator (|) to send the module names to Remove-Module. It uses the Verbose common parameter to get detailed information about the members that are removed.

The Verbose messages show the items that are removed. The messages differ because the BitsTransfer module includes an assembly that implements its cmdlets and a nested module with its own assembly. The PSDiagnostics module includes a module script file (.psm1) that exports functions.







Example 4

C:\PS>$a = get-module BitsTransfer

C:\PS> remove-module -moduleInfo $a

Description
-----------
This command uses the ModuleInfo parameter to remove the BitsTransfer module.
