EXPUNGE {objects}

Use commas to delimit more than one object.

Arguments:

  {objects}             One or more objects to expunge.

Overview:

The EXPUNGE command erases any {objects} marked deleted and
removes them from their containers.  If {objects} is an
undeleted container, its subobjects are searched for deleted
objects to expunge.  EXPUNGE has no effect on an undeleted
object itself.  An expunged object is not recoverable.
