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

       expire - Usenet article and history expiration program

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

       Expire scans the history(5) text file <pathdb in inn.conf>/history and uses  the  informa-
       tion  recorded in it to purge itself or old news articles.  And if the article whose stor-
       age method has self expire functionality, the control file  is  ignored	except	``/remem-
       ber/''  line  for that article by default.  In this case, expire probes the article to see
       if it still exists.  If it does not exist, expire purges the relevant entries.  To disable
       this,  use  the	``-N''	flag.	If ``groupbaseexpiry'' in inn.conf is true, expire always
       treats all stored articles whose storage method have self expire functionality  regardless
       of  its	actual	method.   In this case ``-e'', ``-k'', ``-N'', ``-p'', ``-q'', ``-w'' and
       ``-z'' flags are ignored.

       Note that expire never purges articles which do not match any entry.

       -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  suc-
	      cessfully completed the expiration.  The calling script should install the new his-
	      tory file and un-pause the server.  The ``-r'' flag should be used with this  flag.
	      -f  To  specify an alternate history file, use the ``-f'' flag.  This flag is valid
	      if ``-d'' flag is used together, and the output will be written to this file.   The
	      default without ``-f'' flag is ``history.''

       -g     If  the  ``-g''  flag is given, then a one-line summary equivalent to the output of
	      ``-v 1'' and preceded 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(3)	database to determine the size of the new one.	If ``-d'' flag is
	      not used together, and the output file name will be with an  extension  of  ``.n.''
	      The default without ``-h'' flag is <pathdb in inn.conf>/history.

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

       -N     If the article whose storage method has self expire functionality, then the control
	      file is ignored for that article by default.  If the ``-N'' flag	is  used,  expire
	      still uses the control file in this case.

       -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  expira-
	      tion  programs that base their decisions on the article's posting date.  To use the
	      article's posting date, use the ``-p'' 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.

       -t     If the ``-t'' flag is used, then expire will generate a list  of	the  tokens  that
	      should  be removed on its standard output, and the new history file will be left in
	      history.n, history.n.dir, history.n.index and history.n.hash.  This flag be  useful
	      for  debugging  when  used  with the ``-n'' 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  mes-
	      sages  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 num-
	      ber 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'' and ``-t'' flags to see how  dif-
	      ferent 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 delayrm 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 <pathetc in inn.conf>/expire.ctl is read.
