fi
NOW=$(date +%Y%m%d%H%M)
tmsh save /sys config
echo "backing up to /config/bigip.conf.${NOW}"
cp -a /config/bigip.conf /config/bigip.conf.${NOW}
echo replacing $(grep -c "^ */Common/$1\$" bigip.conf) instances of $1 with $2
sed -e "s~^\( */Common\)/$1$~\1/$2~g" \
 < /config/bigip.conf.${NOW} \
 > /config/bigip.conf
echo "# test with this:"
echo "tmsh load /sys config verify"
echo "# do this if /config/bigip.conf looks good"
echo "tmsh load /sys config"
