There's an easy way to get started with using the command-line interface. That's to get the basic command you need to execute via the GUI, and to modify that command to suit your needs. For example, if you would basically like to get the list of destinatino IP addresses corresponding to a particular flow pattern, but you would like to aggregate the results in a way that are not supported by teh GUI, or to specify additional criteria as part of the filter, then you can run the basic query in the GUI while at the same time obtaining the command. The way to obtain the command is by appending the string ``&v=1'' to the URL in the search string.
