Extracting substring within string between 2 token within the string
Hello.


First best wishes for everybody.


here is the input file ("$INPUT1") contents :
Code:
BASH_FUNC_message_begin_script%%=() {  local -a L_ARRAY;
BASH_FUNC_message_debug%%=() {  local -a L_ARRAY;
BASH_FUNC_message_end_script%%=() {  local -a L_ARRAY;
BASH_FUNC_message_error%%=() {  local -a L_ARRAY;

This simple sed command works well for some kind of tokens.
These tokens work well

Code:
TOKEN1="^BASH_FUNC_"
TOKEN2="\%\%\=\(\)"
#
# # between but excluding TOKEN1 and TOKEN2
#
sed -e 's/'$TOKEN1'\(.*\)'$TOKEN2'.*/\1/'  "$INPUT1"

Which return :
Code:
message_begin_script
message_debug
message_end_script
message_error

Another working example
Code:
#
# # between but including TOKEN1 and excluding TOKEN2
#
sed -e 's/\('$TOKEN1'.*\)'$TOKEN2'.*/\1/'  "$INPUT1"

which return
Code:
BASH_FUNC_message_begin_script
BASH_FUNC_message_debug
BASH_FUNC_message_end_script
BASH_FUNC_message_error

Now I have another token2 of this kind : TOKEN2="local -a L_ARRAY"
And I got an error
Code:
TOKEN1="^BASH_FUNC_"
TOKEN2="local -a L_ARRAY"
#
# # between but excluding TOKEN1 and TOKEN2
#
sed -e 's/'$TOKEN1'\(.*\)'$TOKEN2'.*/\1/'  "$INPUT1"

Code:
sed -e 's/'^BASH_FUNC_'\(.*\)'local -a L_ARRAY'.*/\1/'  "/tmp/MY_INPUT1.txt" 
sed: -e expression #1, char 24: unterminated `s' command

I have tried to escape space and '-' without success
Any help is welcome

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.
