In a similar way, the "<" character before a tab can be used to automatically fill in the default value
for a parameter if no value has yet been set. For example:
add LogReceiverSyslog example Address=example_ip LogSeverity=< (tab)
Will fill in the default value for LogSeverity:
add LogReceiverSyslog example Address=example_ip
LogSeverity=Emergency
However, if the "." character is used instead:
add LogReceiverSyslog example Address=example_ip LogSeverity=. (tab)
A list of all possible values is given:
add LogReceiverSyslog example Address=example_ip
LogSeverity=Emergency,Alert,Critical,Error,Warning,Notice,Info
This list can then be edited with the back arrow and backspace keys.
Object Categories
It has been mentioned that objects are grouped by type, such as IP4Address. Types themselves are
grouped by category. The type IP4Address belongs to the category Address. The main use of
categories is in tab completion when searching for the right object type to use.
If a command such as add is entered and then the tab key is pressed, NetDefendOS displays all the
available categories. By choosing a category and then pressing tab again all the object types for that
category is displayed. Using categories means that the user has a simple way to specify what kind of
object they are trying to specify and a manageable number of options are displayed after pressing
tab.
Not all object types belong in a category. The object type UserAuthRule is a type without a category
and will appear in the category list after pressing tab at the beginning of a command.
The category is sometimes also referred to as a context.
Selecting Object Categories
With some categories, it is necessary to first choose a member of that category with the cc (change
category) command before individual objects can be manipulated. This is the case, for example,
with routes. There can be more than one routing table, so when adding or manipulating a route we
first have to use the cc command to identify which routing table we are interested in.
Suppose a route is to be added to the routing table main. The first command would be:
gw-world:/> cc RoutingTable main
gw-world:/main>
Notice that the command prompt changes to indicate the current category. We can now add the
route:
gw-world:/main> add Route Name=new_route1 Interface=lan Network=lannet
To deselect the category, the command is cc on its own:
gw-world:/main> cc
