Bug Regexp and sed problem
Basically it should identify what ever is in between /*< >*/ (tags) and replace dbname ending with (.) with the words in between the tags

i.e.

Code:
    DELETE FROM /*<workDB>*/epd_test./*<multi>*//*<version>*/epd_tbl1 ALL; into 
    
    
   DELETE FROM /*<workDB>*/${workDB}./*<multi>*//*<version>*/${multi}${version}_epd_tbl1 ALL;

one more example

Code:
       DELETE FROM /*<abcDB>*/epd_test./*<multi>*//*<version>*/epd_tbl1 ALL; into 
       
       
   DELETE FROM /*<abcDB>*/${abcDB}./*<multi>*//*<version>*/${multi}${version}_epd_tbl1 ALL;

what I was thinking was to remember /*< as pattern 1 i.e \(\/\*<\) and workDB as one more pattern >*/ as one more pattern and identify until the
period and replace as above? Is this doable

and similarly for dates it replace with in the single quotes with out using from_dt










sample.sql contains:
Code:
 
DELETE FROM /*<workDB>*/epd_test./*<multi>*//*<version>*/epd_tbl1 ALL;

 
INSERT INTO /*<workDB>*/epd_test./*<multi>*//*<version>*/epd_tbl1
SELECT
  *
FROM
  /*<finDB>*/epd_fin.pr_tbl
WHERE
      (   epd_dt >= cast(/*<from_date>*/'2007-01-01' as date)
      AND epd_dt < cast(/*<to_date>*/'2009-09-14' as date)
      )
  OR  (   epd_cre_dt >= cast(/*<from_date>*/'2007-01-01' as date)
      AND epd_cre_dt < cast(/*<to_date>*/'2009-09-14' as date)
      )
      
    ;

output should be:

Code:
 
DELETE FROM /*<workDB>*/${workDB}./*<multi>*//*<version>*/${multi}${version}_epd_tbl1 ALL;

INSERT INTO /*<workDB>*/${workDB}./*<multi>*//*<version>*/${multi}${version}_epd_tbl1
SELECT
  *
FROM
  /*<finDB>*/${finDB}.pr_tbl
WHERE
      (   epd_dt >= cast(/*<from_dt>*/'${from_dt}' as date)
      AND epd_dt < cast(/*<to_dt>*/'${to_dt}' as date)
      )
  OR  (   epd_cre_dt >= cast(/*<from_dt>*/'${from_dt}' as date)
      AND epd_cre_dt < cast(/*<to_dt>*/'${to_dt}' as date)
      )
      
    ;


Thanks in advance

irsend

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.
