If you have a need in your environment to apply updates without having a new Kernel being applied, then the following should help you accomplish this goal.


This script checks for available updates and removes any kernel related update and applies the rest, and if there are no updates then it will exit with “No Updates Available”.


Copy the text below into a file preferably named or download it here.

# This script is intended to apply updates from rug without installing the kernel updates.

RUGBIN=`which rug`

TMPPatches=`mktemp -t patches.XXXXXXXXXX` || exit 1

if [ -e $RUGBIN ]; then
$RUGBIN lu | sed -e '/--/ d' -e '/Name/ d' -e '/kernel/ d' | awk '{ OFS="-"; print $6,$8 }' | tr "\n" " " | sed -e '$s/-.$//' -e '1s/..//' >> $TMPPatches

if [ "$update" != "" ]; then
echo "Executing rug to patch your system..."

# You can add a -y to supress the yes/no option given
# $RUGBIN in $update -y
$RUGBIN in $update

echo "No Updates Available."

rm $TMPPatches

Once you have this shell script created you can save it in /root/bin or something with the chmod 755 permissions on it. Now you are ready to set it up to run as a Cron Job or use it as you desire.
