crosspost(8)


NAME

   crosspost - create the links for cross posted articles

SYNOPSIS

   crosspost [ -D dir ] [ -s ] [ file...  ]

DESCRIPTION

   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.

   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,Ap,WR:/usr/lib/news/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 /var/spool/news.

   By  default  crosspost  will  fsync(2)  each article after updating the
   links.  The ``-s'' flag can be used to prevent this.
