Excellent!!! May I make one suggestion? Add $HOSTNAME in a couple
places, so if you have multiple computers you know which one needs to
be updated.
########################
#!/bin/sh
PATH=/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/usr/local/sbin
yum check-update >>/dev/null
STATUS=$?
if [ "$STATUS" -eq 100 ]; then
echo "CentOS RPM updates are available for $HOSTNAME" | mail -s "Updates
Available for $HOSTNAME" root
fi
