NAME
mkhistory - rebuild news history file
SYNOPSIS
/usr/libexec/news/maint/mkhistory
[
-s
sizemultiplier ]
DESCRIPTION
Mkhistory
rebuilds the history file and its auxiliaries to match the articles
in /var/news.
Normally
mkhistory
uses a reasonable default size for the
dbz(3Z)
index database; if the
-s
option is given, the expected number of entries in the history database
is taken to be the number of articles found in /var/news times
sizemultiplier.
Mkhistory
is fairly slow and locks the whole news
system for the duration of the run, so it should not be run casually.
FILES
/etc/news/historyhistory file
/etc/news/history.pagdbm database for history file
/etc/news/history.dirdbm database for history file

BUGS
Mkhistory
is inherently incapable of reconstructing history-file lines corresponding
to expired articles.
Protection against old articles reappearing is thus somewhat limited for
a while after the history file is rebuilt.
