overchan - update the news overview database
overchan [ - | file
]
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
was originally designed to be used by InterNetNews or the C News ``mkov'' packages
to update the database as the articles come in. For current inn, the database
is stored by overview method. This can be done within innd(8)
but, still
overchan(8)
can do this, if <useoverchan in inn.conf> is ``true'' and appropriate
setup is done in newsfeeds(5)
. file, for example:
overview!:*:Tc,WnteO:<pathbin
in inn.conf>/overchan
This data consists of a line of text, separated into
four parts by a space. The first part is a token for the article. The second
part is time when the article was received. The third part is time when
the article will be expired(which represents Expires header.) The fourth
part is the data to be stored. 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.
