NAME

       overchan - update the news overview database

SYNOPSIS

       overchan [ -D dir ] [ -c ] [ file...  ]

DESCRIPTION

       Overchan  reads  article  data from files or standard input if none are specified.  (A single dash in the
       file list means to read standard input.)  It uses this information to update the news overview  database.
       Overchan is designed to be used by InterNetNews or the C News ``mkov'' packages to update the database as
       the articles come in.  The database for each newsgroup is stored in a file named .overview in a newsgroup
       directory within the overview database tree.

       Overchan  locks the database file (by locking an auxiliary file) before appending the new data.  To purge
       data after articles have been expired, see expireover(8).

       By default, overchan processes its input as an INN overview stream written  as  a  ``WO''  entry  in  the
       newsfeeds(5) file, for example:

              overview:*:Tc,WO:/usr/lib/news/bin/overchan

       This data consists of a line of text, separated into two parts by a tab.  The first part is a list of all
       relative pathnames where the article has been written, with a single space between entries.   The  second
       part is the data to be written into the overview file, except that the initial article number is omitted.
       The data in the overview files should be expired by running expireover(8).   This  is  normally  done  by
       adding the ``expireover'' flag to the news.daily(8) invocation.

OPTIONS

       -c     To  process  the  output of the mkov(8) program, use the ``-c'' flag.  This format is described in
              the ``nov'' distribution.

       -D     The ``-D'' flag can be used to specify where the databases are stored.  The default  directory  is
              /var/spool/news/over.view.
