I recover the parameters from a file of configuration in this way:

Code:
##### Constants
# recover properties from file
. ../cfg/init.cfg

these are the values:

Code:
 
DIRLIST="20101227 20101228 20101229"
OUTDIR_MOD1="/data/remote/filter/output/"
dir_log="="/data/remote/filter/log/"

works on 44 directory and round 660000 file(compressed) what they contain 1500 rows each.
LIST_1_$RepDate.tmp (LIST_1_20110126_102312.tmp) it contains the list of the files
to elaborate, this is a part of the content:

Code:
 
NC_AN01MSC_GSM_20101227_5493*
NC_AN01MSC_GSM_20101227_5507*
NC_AN01MSC_GSM_20101227_5508*

the character "*" to end line he has on purpose put, because it serves in this format
for an following operation sql:
Code:
#########################################
# F.ne: Updateout
#########################################
UpdateOut()
{
isql -U$USER_DB -P$PWD_OPER -S$SERVER -D$DB_OPER w1000 << THEEND >> ${LogFILENAME}
set nocount on
go
UPDATE $DB_OPER..KPI_FILTERED set NUM_CDR_OUTPUT=${1}
WHERE FILE_NAME LIKE '${2}'
go
quit
THEEND
}

all this correctly works...the variables arrive cleaning up, the problem I think both
this operation:

Code:
CDRO_TOT=`echo "$CDRO - $CDRHDTR" | bc`

do you know a faster and effective method(no expr)?

I in advance thank you,
Germano

irsend

IRSEND(1)							   User Commands							 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.
