BASH, HASH and AWK

Hi,

I am working on this idea that I want to process some information from a command dump.

Using the dump I will search for a string. If it finds the string, it must post a
different/associated string to output/logfile.
Example:
'Find "cookie jar"' then 'echo "carpool/tomorrow" > logfile'

It does not stop with 1 string to search for, it will have around 100 different
strings to search for, and everyone have some other content assigned to it, thus it
should be some clever loop.
I COULD have written one grep for each value, but since it is growing by the day,
I find that a waste of lines and bytes.

To prevent an infinite loop, it should remove what it has already found from the
sourcelist of what to search for or somehow mark it as processed.
(The sourcelist is overwritten each time the PC boots with an updated one)

The tricky bit for me is both how I can arrange it with a HASH table, I've done
something similar in PERL, but in BASH/AWK I am unable to do this. The system is very
limited and its not permitted toexpand on its available apps by any byte atm.

I've drawn out how I think the design is going to work.

In itself, there are several commands it will search the output for, but I am used to
having a launch script, that then uses a "core search" script with the variables that
designs it to that and that output file, predefined variables file and logfile.
It gives control and scalabillity ;-)

(The pink area is where the core script loops in itself to search for every available word)

Is this hard to acomplish?
I've written some BASH scripts in the past, aswell as some BATCH and PERL scripts,
though nothing close to this complexity.

dump

dump(n) 																   dump(n)

__________________________________________________________________________________________________________________________________________________

NAME

       dump - Dump information about Tcl interpreter in TkCon

SYNOPSIS

       dump method ?-nocomplain? ?-filter pattern? ?--? pattern ?pattern ...?

_________________________________________________________________

DESCRIPTION

       The  dump  command  provides  a way for the user to spit out state information about the interpreter in a Tcl readable (and human readable)
       form.  It takes the general form:

       dump method ?-nocomplain? ?-filter pattern? ?--? pattern ?pattern ...?

       The patterns represent glob-style patterns (as in string match pattern $str).  -nocomplain will prevent dump from throwing an error  if	no
       items matched the pattern.  -filter is interpreted as appropriate for the method.  The various methods are:

       dump command args
	      Outputs one or more commands.

       dump procedure args
	      Outputs one or more procs in sourceable form.

       dump variable args
	      Outputs  the values of variables in sourceable form.  Recognizes nested arrays.  The -filter pattern is used as to filter array ele-
	      ment names and is interepreted as a glob pattern (defaults to {*}).  It is passed down for nested arrays.

       dump widget args
	      Outputs one or more widgets by giving their configuration options.  The -filter pattern is used as to filter the config options  and
	      is interpreted as a case insensitive regexp pattern (defaults to {.*}).
