NAME

mkhistory - rebuild news history file

SYNOPSIS

/usr/lib/news/maint/mkhistory [ -s sizemultiplier ]

DESCRIPTION

Mkhistory rebuilds the history file and its auxiliaries to match the articles in /var/spool/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/spool/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.

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.
