expireover - Expire entries from the news overview database
expireover [ -a ] [ -D overviewdir ] [ -f file ] [ -n ] [ -O overview.fmt
] [ -s ] [ -v ] [ -z ] [ file... ]
Expireover expires entries from the news overview database. It reads a
list of pathnames (relative to the spool directory,
<config$_PATH_SPOOL>), from the specified files or standard input if none
are specified. (A file name of ``-'' may be used to specify the standard
input.) It then removes any mention of those articles from the
appropriate overview database.
-z If the ``-z'' flag is used, then the input is assumed to be sorted
such that all entries for a newsgroup appear together so that it can
be purged at once. This flag can be useful when used with the
sorted output of expire(8) 's ``-z'' flag.
-s If the ``-s'' flag is used, then expireover will read the spool
directory for all groups mentioned in the active(5) file, and remove
the overview entries of any articles that do not appear in the
-f To specify an alternate file, use the ``-f'' flag; a name of ``-''
is taken to mean the standard input.
-a The ``-a'' flag reads the spool directory and adds any missing
overview entries. It will create files if necessary. This can be
used to initialize a database, or to sync up a overview database
that may be lacking articles due to a crash. Overchan should be
running, to ensure that any incoming articles get included. Using
this flag implies the ``-s'' flag; the ``-f'' flag may be used to
add only a subset of the newsgroups.
-v To see a list of the entries that would be added or deleted, use the
-n To perform no real updates, use the ``-n'' flag.
-D The ``-D'' flag can be used to specify where the databases are
stored. The default directory is <config$_PATH_OVERVIEWDIR>.
-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.
