Crosspost
reads group and article number 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 create the hard, or symbolic, links for
cross posted articles.
Crosspost
is designed to be used by InterNetNews
to create the links as the articles come in.
Normally innd creates the links but by having
crosspost
create the links innd spends less time waiting for disk IO.
In this mode one would start
innd(8)
using the ``-L'' flag.
If
storageapi
is turned on at inn.conf,
crosspost
is not needed since it is for traditional spool.
Crosspost
expects input in the form:
group.name/123 group2.name/456 group3.name/789
with one line per article. Any dots in the input are translated
into ``/'' to translate the news group into a pathname.
The first field is assumed to be the name of an existing copy of the
article.
Crosspost
will attempt to link all the subsequent entries to the first using
hard links if possible or symbolic links if that fails.
By default,
crosspost
processes its input as an INN channel feed written as a ``WR'' entry
in the
newsfeeds (5)
file, for example:
crosspost!:*:Tc,WR:<PREFIX specified with --prefix at configure>/bin/crosspost
To process the history file and re-create all the links for all articles
use:
awk <history -F' ' '(NF > 2){print $3}' | crosspost
(where the ``-F'' is followed by a tab character.)
The ``-D'' flag can be used to specify where the article spool is stored.
The default directory is
<patharticles\ in\ inn.conf> .
By default
crosspost
will fsync(2) each article after updating the links. The ``-s'' flag
can be used
to prevent this.
