I read up on what you were doing with match and RLENGTH and RSTART, but I'm having a little trouble wrapping my head around the code itself.

Bear with me as I try to go through this:
Code:
BEGIN {
  FS="[/]"  #setting the FS to / .. I assume for the /home/dir1/ part of my pattern space..                                         
}
/^--/ {block++;print;next}  #look for -- at the start of line.  Unsure of the significance of incrementing the block... print the -- and move to the next line 
block {
  match($NF, "^.*-.*-[^-][^-]*-")  #regexp matching the "file" portion of my pattern (file-egress-filter-) .. not sure on the exclusion of dashes ([^-])..
  printf("%s\n", substr($NF, 1, RLENGTH-1)) #print newline, then print the line, starting at the first position and the whole string minus the last character.
}
{
  !(block) && ($0 ~ ":") ? match($NF, ":[^:][^:]*$") : match($NF, "-[^-][^-]*$") #if the line was not matched on the previous regexp (block) and contains a : then match on a : then no colon until the end of the line?
  printf("%s\n", substr($NF, RSTART+1)) #kinda lost here... is it saying print 1 position after the match? ..so after the :?
  block=0  #once again, not sure on the significance of the count. 
}

So, I realize that probably way off... I'll play more with awk.

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.
