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.
