oldbid

     The 'oldbid' command is used to invoke the process which
deletes old message-id's (or bids) in the Historyfile.  The default
location of Historyfile is /spool/history.  Do not confuse this
file with the NNTP History database, stored in /spool/news/history
by default!

    oldbid  [interval  age_in_days]

     Begin the oldbid process every <interval> hours, and delete
     those bids which are older than <age_in_days> days.  If no
     arguments are provided, the current oldbid interval and age
     are displayed.


          Example:  To expire bids every 24 hours, that are 30 days
          old, use:  oldbid  24  30
