hmmm...it doesn't work, this is awk science fiction for me. Reading trough man to try figure out

Code:
#!/bin/bash

NETSTAT=$(netstat -ntp | awk '{ print $4 }' | grep -v "127.0.0.1" | cut -d ":" -f1 | grep "^[0-9]")
APACHE=$(grep -R "<VirtualHost " /etc/apache2/* | cut -d ":" -f2 | cut -d " " -f2 |  cut -d ">" -f1 | grep "^[0-9]")

USE=("${NETSTAT[@]}\n${APACHE[@]}")
USED=$( printf "${USE[@]}" | sort | uniq)
IFCONFIG=$(ifconfig -a | grep -v "127.0.0.1" | grep addr | awk '{ print $2 }' | cut -d ":" -f2 | grep "\.")


awk '{
    c=split(ENVIRON["USED"], used, "\n");
    d=split(ENVIRON["IFCONFIG"], ifconfig, "\n");
 
    for (i=1; i<=c; i++) {use[used  [i]]=used[i]; all[used[i]]=used[i];}
    for (i=1; i<=d; i++) {ifc[ifconfig[i]]=ifconfig[i]; all[ifconfig[i]]=ifconfig[i];}

    for (i in all) {
       if (i in ifc && i in use) common[i]=i;
       if (i in ifc && !(i in use)) ifc_only[i]=i;
       if (!(i in ifc) && i in use) use_only[i]=i;
    }
 
    for (i in common  ) print "Common IPs      : " i;
    for (i in use_only) print "In APACHE only  : " i;
    for (i in ifc_only) print "In IFCONFIG only: " i;
}'

AMANDA-SCRIPTS(7)						    Miscellanea 						 AMANDA-SCRIPTS(7)

NAME

       amanda-scripts - Configuring and using the Script API

DESCRIPTION

       The Script API is a flexible system for invoking user-supplied scripts at various points in the execution of Amanda. This manual page
       describes the operation and configuration of the API. For help writing Script API scripts, see http://wiki.zmanda.com/index.php/Script_API.

SCRIPTS

       This section lists the scripts included with Amanda, see the individual man page for instructions on using them. For complete How-To
       information, consult the Amanda wiki at http://wiki.zmanda.com.

       o   amzfs-snapshot(8), - create/destroy zfs snapshot.

       o   script-email(8), - send email.

       Script properties work just like application properties: they are insensitive to case, and - (dash) and _ (underscore) may be used
       interchangeably.

SCRIPTS OUTPUT PROPERTY

       A pre-dle-amcheck, pre-dle-estimate or pre-dle-backup executed on the client can output property on stdout that are sent to the
       application. If the output line matches "PROPERTY str1 str2", Amanda sets a property called "str1" by the value of "str2", that property is
       sent to the application.
