actually that's the least of my problems now. i believe i'll be able to figure that out at the end. but the only other question i have is, lets say the first time i run this command, i get and output similar to this:

Code:
first run:
/data/projects/file01,300lines,130lines matching 'Customer.*Processed'

(note, this is just one file out of many that would be in the output.)

now, the above output is saved to a file called /tmp/results.txt
the second time i run this command, say 5 minutes later, there'd be a line in the output similar to:

Code:
second run:
/data/projects/file01,410lines,139lines matching 'Customer.*Processed'

now, i dont want to search through each file again. i want to begin from the point where the last scan left off.

in the first run, there were 300 lines in the file named '/data/projects/file01. I want it so that, the next time i run the script, awk can begin from line 301 to the end of the file. and i want to have this happen for all the files it finds in the directory. this way, only the first run will be slow. all runs after that will be fast.

here's my attempt to modify your code:
Code:
lastlinenumber=$(awk -F"," '{print $2}' /tmp/results.txt | sed 's/lines//g')

awk    -v LLNUM=${lastlinenumber}  'FNR == 1               {if (NR > 1) {print fn, "text1", fnr, "text2", nl}
                                 fn=FILENAME; fnr = 1; nl = 0}
                                {fnr = FNR}
         /customer.*processed/  && NR>LLNUM {nl++}
         END                    {print fn, "text1", fnr, "text2", nl}
        ' file?

if while comparing the most recent list of files in the latest scan, it finds a file that didn't exist in the previous scan, it'll scan that file in its entirety because it would be considered new.

IRSEND(1)								FSF								 IRSEND(1)

NAME

       irsend - basic LIRC program to send infra-red commands

SYNOPSIS

       irsend [options] DIRECTIVE REMOTE CODE [CODE...]

DESCRIPTION

       Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such
       as TV boxes, HiFi sets, etc.

       DIRECTIVE can be:
	  SEND_ONCE	    - send CODE [CODE ...] once
	  SEND_START	    - start repeating CODE
	  SEND_STOP	    - stop repeating CODE
	  LIST		    - list configured remote items
	  SET_TRANSMITTERS  - set transmitters NUM [NUM ...]
	  SIMULATE	    - simulate IR event

       REMOTE is the name of a remote, as described in the lircd configuration file.

       CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file.

       NUM is the transmitter number of the hardware device.

       For the LIST DIRECTIVE, REMOTE and/or CODE can be empty:

	  LIST	 ""    ""   - list all configured remote names
	  LIST REMOTE  ""   - list all codes of REMOTE
	  LIST REMOTE CODE  - list only CODE of REMOTE

       The SIMULATE command only works if it has been explicitly enabled in lircd.

       -h --help
	      display usage summary

       -v --version
	      display version

       -d --device
	      use given lircd socket [/var/run/lirc/lircd]

       -a --address=host[:port]
	      connect to lircd at this address

       -# --count=n
	      send command n times

EXAMPLES

	  irsend LIST DenonTuner ""
	  irsend SEND_ONCE  DenonTuner PROG-SCAN
	  irsend SEND_ONCE  OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
	  irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
	  irsend SEND_STOP  OnkyoAmpli VOL-DOWN
	  irsend SET_TRANSMITTERS 1
	  irsend SET_TRANSMITTERS 1 3 4
	  irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"

FILES

       /etc/lirc/lircd.conf
	      Default lircd configuration file.  It should contain all the remotes, their infra-red codes and the corresponding timing	and  wave-
	      form details.

DIAGNOSTICS

       If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:
       "irsend: could not connect to socket"
       "irsend: Connection refused" (or "Permission denied").

SEE ALSO

       The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory.
