Hey all,
Since we are on the yum topic...I have a little shell script that I put
in /etc/cron.daily/, that checks for updates and emails root if updates
are available. Otherwise, if no updates are available, it is silent.
Here it is:
########################
#!/bin/sh
PATH=/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/usr/local/sbin
yum check-update >>/dev/null
STATUS=$?
if [ "$STATUS" -eq 100 ]; then
echo "CentOS RPM updates are available" | mail -s "Updates
Available" root
fi
#########################
If you want it to actually email your personal email address, either
change "root" to your email address, or better yet -- set up
/etc/aliases to forward root's email to your personall address. If you
do that be sure to run newaliases when you are done editing that file.
