Determine completed % for a query

Question

Oracle 9.2.0.8
SQL*Plus
I have a huge table. If I delete some records from that table, because of a huge number it's not completing in 1 hr. then I kill the session.
Is there any way to know how may records has been processed (deleted), before I kill the session?
In this case, after 1 hr if it has processed 80% of records I can determine how much time it's going to take.
Giving generic example as I am facing this situation may times.
Thanks

Hi,
USe this query regularly and you find a big difference in used or free space.
