Delete data in the RTDB.
This directive gives the user a way to delete simple entries from the database. The general form of the directive is as follows:
UNSET <string name>[*]
This directive cannot be used with complex objects such as geometries
and basis sets. Complex objects are stored using a structured naming
convention that is not matched by a simple wild card. A wild-card
specified at the end of the
string <name> will cause all entries whose
name begins with that string to be deleted. This is very useful as a way
to reset modules to their default behavior, since modules typically
store information in the database with names that begin with module:.
For example, the SCF program can be restored to its default behavior by
deleting all database entries beginning with scf:, using the directive
The section on fragment guess has an example using unset on a water dimer calculation.
The following example makes an entry in the database using the SET directive, and then immediately deletes it using the UNSET directive:
set mylist 1 2 3 4 unset mylist
