I have written following script to get similar functionality to cron-apt configured in download-only mode. I will get notification email if my system is not fully updated. Update rpms are downloaded, so they can be immediately installed.

It is trivial to modify this script to automatically install updates.

#!/bin/bash
#
# show available updates
# up2date version

DOWNLOAD_UPDATES=”yes”

UP2DATE_OUT=”`up2date -l | sed ’0,/^—–/d’`”

if [ "$UP2DATE_OUT" != "`echo -e '\n'`" ]; then

if [ "$DOWNLOAD_UPDATES" = "yes" ]; then

echo ‘Downloading updated RPMs:’
echo ‘————————-’
up2date -u -d

else

echo ‘Out of date packages:’
echo ‘———————’
echo

echo “$UP2DATE_OUT”
echo

fi
