OVERVIEW.FMT(5) 						File Formats Manual						   OVERVIEW.FMT(5)

NAME
overview.fmt - format of news overview database DESCRIPTION
The file /etc/news/overview.fmt specifies the organization of the news overview database. Blank lines and lines beginning with a number sign (``#'') are ignored. The order of lines in this file is important; it determines the order in which the fields will appear in the database. Most lines will consist of an article header name, optionally followed by a colon. A trailing set of lines can have the word ``full'' appear after the colon; this indicates that the header should appear as well as its value. If this file is changed, it is usually necessary to rebuild the existing overview database using expireover(8) after removing all existing overview files. The default file, show below, is compatible with Geoff Collyer's ``nov'' package: Subject: From: Date: Message-ID: References: Bytes: Lines: ## Some newsreaders get better performance if Xref is present #Xref:full HISTORY
Written by Rich $alz <rsalz@uunet.uu.net> for InterNetNews. Intended to be compatible with the nov package written by Geoff Collyer <geoff@world.std.com>. This is revision 1.6, dated 1996/09/06. OVERVIEW.FMT(5)

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. HISTORY
Written by Rob Robertson <rob@violet.berkeley.edu> and Rich $alz <rsalz@uunet.uu.net> for InterNetNews. This is revision 1.9, dated 1996/10/29. SEE ALSO
