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.
