       expire - Usenet article and history expiration program


       expire  [  -d dir ] [ -e ] [ -f file ] [ -g file ] [ -h file ] [ -i ] [
       -l ] [ -n ] [ -p ] [ -q ] [ -r reason ] [ -s ] [ -t ] [ -v level ] [ -w
       number ] [ -x ] [ -z file ] [ expire.ctl ]


       Expire  scans  the  history(5) text file /var/lib/news/history and uses
       the information recorded in it to purge old news articles.


       -d     If the ``-d'' flag is  used,  then  the  new  history  file  and
              database  is  created  in the specified directory, dir.  This is
              useful when the filesystem does not  have  sufficient  space  to
              hold  both  the  old  and  new history files.  When this flag is
              used, expire leaves the server paused and creates a  zero-length
              file  named  after  the  new  history file, with an extension of
              ``.done'' to indicate that it  has  successfully  completed  the
              expiration.   The  calling script should install the new history
              file and un-pause the server.  The ``-r'' flag  should  be  used
              with this flag.

       -e     If  the  ``-e''  flag  is  used, then as soon as the first cross
              posting of the article expires, all copies of it are removed.

       -f     To specify an alternate history file, use the ``-f'' flag.

       -g     If the ``-g'' flag is given, then a one-line summary  equivalent
              to the output of ``-v1'' and preceeded by the current time, will
              be appended to the specified file.

       -h     To specify an alternate input text history file, use the  ``-h''
              flag.   Expire  uses  the  old dbz(3z) database to determine the
              size of the new one.

       -i     To ignore the old database, use the ``-i'' flag.

       -l     Expire normally just unlinks each file if it should be  expired.
              If  the  ``-l''  flag is used, then all articles after the first
              one are treated as if they could be symbolic links to the  first
              one.   In  this  case,  the first article will not be removed as
              long as any other cross-posts of the article remain.

       -n     If innd is not running, use the ``-n'' flag and expire will  not
              send the ``pause'' or ``go'' commands.  (For more details on the
              commands,  see  ctlinnd(8)).   Note  that  expire   only   needs
              exclusive  access  for a very short time — long enough to see if
              any new articles arrived since it first hit the end of the file,
              and to rename the new files to the working files.

       -p     Expire  makes  its decisions on the time the article arrived, as
              found in the history file.  This means articles are often kept a
              little  longer  than  with  other  expiration programs that base
              their decisions on the  article's  posting  date.   To  use  the
              article's posting date, use the ``-p'' flag.

       -q     Expire  normally  complains  about  articles  that are posted to
              newsgroups not mentioned in the active file.  To  suppress  this
              action, use the ``-q'' flag.

       -r     Expire  normally  sends a ``pause'' command to the local innd(8)
              daemon when it needs exclusive access to the history file, using
              the  string  ``Expiring''  as  the  reason.  To give a different
              reason, use the ``-r'' flag.  The process ID will be appended to
              the reason.  When expire is finished and the new history file is
              ready, it sends a ``go'' command.

       -s     If the ``-s'' flag is used, then expire  will  print  a  summary
              when  it  exits showing the approximate number of kilobytes used
              by all deleted articles.

       -t     If the ``-t'' flag is used, then expire will generate a list  of
              the files that should be removed on its standard output, and the
              new history file will be left in history.n and history.n.dir and
              history.n.pag.  This flag be useful for debugging when used with
              the ``-n'' and ``-s'' flags.  Note that if the  ``-f''  flag  is
              used,  then  the  name  specified  with  that  flag will be used
              instead of history.

       -v     The ``-v'' flag  is  used  to  increase  the  verbosity  of  the
              program,  generating  messages  to  standard  output.  The level
              should be a number, where higher numbers result in more  output.
              Level  one  will  print  totals of the various actions done (not
              valid if a new history file is  not  written),  level  two  will
              print  report  on each individual file, while level five results
              in more than one line of output for every line processed.

       -w     Use the ``-w'' flag to ``warp'' time so that expire thinks it is
              running  at  some  time  other then the current time.  The value
              should be a signed floating point number of the number  of  days
              to use as the offset.

       -x     If  the ``-x'' flag is used, then expire will not create any new
              history files.  This is  most  useful  when  combined  with  the
              ``-n'', ``-s'', and ``-t'' flags to see how different expiration
              policies would change the amount of disk space used.

       -z     If the ``-z'' flag is used, then articles are not  removed,  but
              their  names  are  appended  to  the  specified  file.   See the
              description of expirerm in news.daily(8).

       If a filename is specified, it is taken as the control file and  parsed
       according  to the rules in expire.ctl(5).  A single dash (``-'') may be
       used to read the file from standard input.  If no  file  is  specified,
       the file /etc/news/expire.ctl is read.
