Search & replace content using awk/gsub
Hi,
I have two files master.txt & reference.txt. Sample below

Master.txt
Code:
2372,MTS,AP
919848001104,Airtel,DL
0819,MTS,MUM
919849788001,Airtel,AP
1430,Aircel MP,20

Reference.txt
Code:
2372,919848701430,46467
919848002372,2372,47195
2372,919849788001,59027
0819,028803,1
0819,029801,1
0819,2372,1

Output which is coming is as follows:
Code:
MTS AP,91984870Aircel MP,46467
91984800MTS AP,MTS AP,47195
MTS AP,Airtel,AP59027
MTS MUM,028803,1
MTS MUM,029803,1
MTS MUM,MTS AP,1

Requirement:
Only the exact match of each separator field should be replaced in reference text,i.e, output should look like as follows

MTS AP,919848701430,46467
919848002372,MTS AP,47195
MTS AP,Airtel,AP59027
MTS MUM,028803,1
MTS MUM,029803,1
MTS MUM,MTS AP,1

Code is
awk -F, '
NR==FNR {rep[$1]=$2" "$3; next}
{ for (r in rep) gsub(r,rep[r],$0); print $0}' Master.txt Reference.txt

Please help in getting the code changed as per the required output for the exact match length

locale::codes::langext5.18

Locale::Codes::LangExt(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangExt(3pm)

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or
       a constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
