Internal data regarding the given newsgroups are displayed.

Overview records are retrieved. The artnumrange parameter may be a single article number, or a range of articles in the format
low-high

- -M
Same as -m, and also displays memory pool statistics for each database file.

Displays information about the given database, as returned by the Berkeley DB db->stat() call. This operation may take a long time on busy systems (several minutes or more).
Warnings
ovdb_stat may be safely killed with the INT, TERM, or HUP signals. It catches those signals and exits cleanly. Do not kill ovdb_stat with other signals, unless absolutely necessary, because it may leave stale locks in the database environment.
