Little script to save and restore ip rules

[Lee Lists <lists@xxxxxxxx>]

Hello,

I would like to have some testers for this script which should save and 
restore ip rules and associated tables.

Thanks

#!/bin/bash
#
# chkconfig: 2345 85 15
# description: save and restore ip rules settings
# config: /etc/sysconfig/iprules

# source function library
. /etc/rc.d/init.d/functions

CONFIG=/etc/sysconfig/iprules

RETVAL=0

case "$1" in
 save)
   echo -n "Saving ip rules:"
   rm $CONFIG > /dev/null 2>&1
   ip ru ls | grep -v "^3276.:" | grep -v "^0:" | sed -e "s/://" -e 
"s/from all//" -e "s/^/ip ru add preference /" |
       echo $LINE >> $CONFIG
   done
   ip ru ls | grep -v "lookup local" | grep -v "lookup main" | grep -v 
"lookup default" | sed -e "s/^.*lookup //" |
       ip ro ls ta $LINE | sed -e "s/$/ ta $LINE/" -e "s/^/ip ro add /" 
>> $CONFIG
   done
   echo
   ;;
 stop)
   echo -n "Stopping ip rules:"
   ip ru ls | grep -v "lookup local" | grep -v "lookup main" | grep -v 
"lookup default" | sed -e "s/^.*lookup //" |
       ip ro flush ta $LINE
   done
   ip ru ls | grep -v "^3276.:" | grep -v "^0:" | sed -e "s/://"  -e 
"s/from all//" -e "s/^/ip ru del preference /"
       /sbin/$LINE
   done
   rm -f /var/lock/subsys/rules
   echo
   ;;
 start)
   echo -n "Starting ip rules:"
   if [ -f /var/lock/subsys/rules ] ; then
           $0 stop
   fi
   # real start
   cat $CONFIG | while read LINE ; do
       /sbin/$LINE
   done
   touch /var/lock/subsys/rules
   echo

   $0 stop
   $0 start
   RETVAL=$?
