In nutanix command-line interface (ncli) commands, each entity has a unique set of actions, but a common action across all entities is LIST.

This is how the Command Format Nutanix Command-Line Interface look like:

ncli> entity action parameter1=value parameter2=value ...

entity can be replaced by cluster or disk, both are Nutanix entities. Other Nutanix entities can also replace entity.
 
action can be replaced by any valid action for the preceding entity.

An example of a command requesting for a list of all storage pools in the cluster looks like this:  
ncli> storagepool list

Some action requires parameters to limit its scope. Thus, parameters are found at the end of the command.
