Assuming you're using bash you can check the exit code with:
echo 'res=cpu,total_guarantee=100' > /config/ckrm/class/shares
echo $?
And you can exit if there was an error in many ways:
trap 'echo "Yikes. There was an error."' ERR
set -e (or was it +e ??)
echo 'res=cpu,total_guarantee=100' > /config/ckrm/class/shares
OR
echo 'res=cpu,total_guarantee=100' > /config/ckrm/class/shares || exit
-1
OR
echo 'res=cpu,total_guarantee=100' > /config/ckrm/class/shares
if [ "$?" != "0" ]; then
echo "error"
fi
