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 Inter-
     NetNews  to  create the links as the articles come in.  Nor-
     mally 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 path-
     name.  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/local/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 /news.

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