ARCHIVE(8)                                                    System Manager's Manual                                                   ARCHIVE(8)

NAME

       archive - Usenet article archiver

SYNOPSIS

       archive [ -a archive ] [ -f ] [ -i index ] [ -m ] [ -r ] [ input ]

DESCRIPTION

       Archive  makes  copies of files specified on its standard input.  It is normally run either as a channel feed under innd(8), or by a script
       before expire(8) is run.

       Archive reads the named input file, or standard input if no file is given.  The input is taken as a set of lines.  Blank  lines  and  lines
       starting  with  a  number sign (``#'') are ignored.  All other lines should specify the name of a file to archive.  If a filename is not an
       absolute pathname, it is taken to be relative to /var/spool/news.

       Files are copied to a directory within the archive directory, /var/spool/news/news.archive.  The default is to create a hierarchy that mim-
       ics  the input files; intermediate directories will be created as needed.  For example, the input file comp/sources/unix/2211 (article 2211
       in the newsgroup comp.sources.unix) will be copied to /var/spool/news/news.archive/comp/sources/unix/2211.

OPTIONS

       -a archive
              If the ``-a'' flag is used then its argument specifies the directory to archive in instead of the default.

       -f     If the ``-f'' flag is used, then all directory names will be flattened out, replacing the slashes with periods.  In this  case,  the
              file would be copied to /var/spool/news/news.archive/comp.sources.unix/2211.

       -i     If  the  ``-i''  flag  is used, then archive will append one line to the specified index file for each article that it copies.  This
              line will contain the destination name and the Message-ID and Subject headers.

       -m     Files are copied by making a link.  If that fails a new file is created.  If the ``-m'' flag is used, then the file will  be  copied
              to the destination, and the input file will be replaced with a symbolic link pointing to the new file.

       -r     By default, archive sets its standard error to /var/log/news/errlog.  To suppress this redirection, use the ``-r'' flag.

EXIT STATUS

       If  the input is exhausted, archive will exit with a zero status.  If an I/O error occures, it will try to spool its input, copying it to a
       file.  If there was no input filename, the standard input will be copied to /var/spool/news/out.going/archive and the  program  will  exit.
       If  an input filename was given, a temporary file named input.bch (if input is an absolute pathname) or /var/spool/news/out.going/input.bch
       (if the filename does not begin with a slash) is created.  Once the input is copied, archive will try to rename this temporary file  to  be
       the name of the input file, and then exit.

EXAMPLES

       A typical newsfeeds(5) entry to archive most source newsgroups is as follows:

              source-archive
                   :!*,*sources*,!*wanted*,!*.d
                   :Tc,Wn
                   :/usr/lib/news/bin/archive -f -i 
                       /usr/spool/news/news.archive/INDEX
