expireover(8): - Expire entries from the news overview database

NAME

   expireover - Expire entries from the news overview database

SYNOPSIS

   expireover  [  -a  ]  [  -D  overviewdir  ]  [  -f  file  ] [ -n ] [ -O
   overview.fmt ] [ -s ] [ -v ] [ -z ] [ file...  ]

DESCRIPTION

   Expireover expires entries from the news overview database.  It reads a
   list  of  pathnames (relative to the spool directory, /var/spool/news),
   from the specified files or standard input if none are  specified.   (A
   file name of ``-'' may be used to specify the standard input.)  It then
   removes any mention of those articles  from  the  appropriate  overview
   database.

OPTIONS

   -z     If  the  ``-z''  flag  is  used, then the input is assumed to be
          sorted such that all entries for a newsgroup appear together  so
          that  it  can  be  purged at once.  This flag can be useful when
          used with the sorted output of expire(8)'s ``-z'' flag.

   -s     If the ``-s'' flag is used, then expireover will read the  spool
          directory  for  all  groups mentioned in the active(5) file, and
          remove the overview entries of any articles that do  not  appear
          in the directory.

   -f     To  specify  an  alternate  file, use the ``-f'' flag; a name of
          ``-'' is taken to mean the standard input.

   -a     The ``-a'' flag reads the spool directory and adds  any  missing
          overview  entries.  It will create files if necessary.  This can
          be used to initialize a database,  or  to  sync  up  a  overview
          database  that may be lacking articles due to a crash.  Overchan
          should be running, to ensure  that  any  incoming  articles  get
          included.   Using  this flag implies the ``-s'' flag; the ``-f''
          flag may be used to add only a subset of the newsgroups.

   -v     To see a list of the entries that would be added or deleted, use
          the ``-v'' flag.

   -n     To perform no real updates, use the ``-n'' flag.

   -D     The  ``-D''  flag can be used to specify where the databases are
          stored.  The default directory is /var/spool/news/over.view.

   -O     The ``-O'' flag may be used to specify an alternate location for
          the  overview.fmt(5)  file;  this  is  normally  only useful for
          debugging.
