Need Help with Trigger

Hi, I've just started learning Oracle and I have some problem creating trigger. Basically, I typed in something like this in PL/SQL:

>create trigger trig_test

 2 after insert or update
 3 on tab1
 4 begin
 5 select * from tab1;
 6 end;
 7 .

Upon hitting enter, no message is displayed and a PL/SQL prompt is returned. After that, when I perform an insert, nothing from tab1 is displayed; only confirmation message that a row has been inserted. When I perform a select * from sys.user_triggers, the table is empty. (If I had successfully created a trigger, the trigger info will be stored in this table, right?) What did I do wrong?

I sincerely thank anyone who may be able to help.
