Summary: yes, running inews and expire will screw up history

Currently if inews/rnews is running when expirs is running you MAY
loose some articles from the history file.

Here is the shell script I  run from crontab to do the expiring. It works.

#! /bin/sh
# This is how I do it on seismo.
umask 002

# Prevent additions to history file while expire is running
mv /usr/bin/rnews /usr/bin/rnews.x
echo 'exec cat >/usr/spool/news/rnews.$$' >/usr/bin/rnews
chmod 4755 /usr/bin/rnews
/etc/chown news /usr/bin/rnews

# actually expire the articles
cd /usr/lib/news
/usr/lib/news/expire -v2

# get a fresh logfile
cd /usr/spool/log
mv news.5 news.6
mv news.4 news.5
mv news.3 news.4
mv news.2 news.3
mv news.1 news.2
mv news.0 news.1
mv news news.0
cp /dev/null news
/etc/chown news news*

# turn rnews loose
mv /usr/bin/rnews.x /usr/bin/rnews
cd /usr/spool/news
for i in rnews.*
do
	/usr/bin/rnews <$i
	rm -f $i
done
