Chapter 1. New Features and the Exchange Management Shell > What Is a Cmdlet?
What Is a Cmdlet?
The cmdlet (pronounced “command let”) is a basic tenant of Exchange Management Shell. It always is formatted as a verb-noun combination. (There are never any spaces between the verb and the noun.) The verb is an action and the noun is the object on which you perform the action. Unless a pipe character (|) appears in the statement, there cannot be more than one cmdlet in a single statement. Everything you do in Exchange Management Shell starts with a cmdlet. Some cmdlets have only a few parameters associated with them (such as the Mount-Database cmdlet), whereas others have many parameters that may be associated with them (such as the New-Mailbox cmdlet). The following table illustrates how two cmdlets could have many differences in terms of their available parameters.
| Mount-Database parameters:

(There are many more configuration options necessary when you create a mailbox versus when you simply need to mount a database.) |
