Thanks for taking the time to reply

I am trying to work with a firewall ruleset. Every DROP rule should have a partner LOG rule. But from the following, you can see that two rules do not have a corresponding LOG rule. So I am trying to process the file and identify all rules I have a DROP but no LOG. The two offenders in this selection below are in BOLD

Code:

set security firewall name Private-to-AA rule 25 action 'drop'
set security firewall name Private-to-AA rule 9999 action 'drop'
set security firewall name Private-to-AA rule 9999 'log'
set security firewall name Private-to-BB default-action 'drop'
set security firewall name Private-to-BB 'default-log'
set security firewall name Private-to-CC default-action 'drop'
set security firewall name Private-to-CC 'default-log'
set security firewall name Private-to-CC rule 9999 action 'drop'
set security firewall name Private-to-CC rule 9999 'log'
set security firewall name Private-to-DD default-action 'drop'
set security firewall name Private-to-DD 'default-log'
set security firewall name Private-to-DD rule 9999 action 'drop'
set security firewall name Private-to-DD rule 9999 'log'
set security firewall name local default-action 'drop'
set security firewall name local rule 10 action 'drop'
set security firewall name local rule 10 'log'

APF(1)							      General Commands Manual							    APF(1)

NAME

       apf - easy iptables based firewall system

SYNOPSIS

       apf

DESCRIPTION

       This  manual page documents briefly the apf command.  This manual page was written for the Debian distribution because the original program
       does not have a manual page.

       Advanced Policy Firewall (APF) is an iptables (netfilter) based firewall system designed around the essential  needs  of  today's  Internet
       deployed  servers  and the unique needs of custom deployed Linux installations. The configuration of APF is designed to be very informative
       and present the user with an easy to follow process, from top to bottom of the configuration file. The management of APF  on  a	day-to-day
       basis  is  conducted from the command line with the 'apf' command, which includes detailed usage information and all the features one would
       expect from a current and forward thinking firewall solution.

OPTIONS

       apf follow the usual GNU command line syntax, with long options starting with two dashes (`-').	A summary of options is included below.

       -s|--start
	      load all firewall rules

       -r|--restart
	      stop (flush) & reload firewall rules

       -l|--list
	      list all firewall rules

       -t|--status
	      output firewall status log

       -e|--refresh
	      refresh & resolve dns names in trust rules

       -a <HOST CMT|--allow <HOST COMMENT>
	      add host (IP/FQDN) to allow_hosts.rules and immediately load new rule into firewall

       -d <HOST CMT|--deny <HOST COMMENT>
	      add host (IP/FQDN) to deny_hosts.rules and immediately load new rule into firewall
