Description:
37
+
This attribute is used to unregister and delete a previously
38
+
created trigger from the list of available triggers. In order to
39
+
achieve this, one should write a positive integer into the
40
+
associated file, representing the id of the trigger that needs
41
+
to be removed. If the trigger can't be found, an invalid
42
+
argument message will be returned to the user.
