Tools Compare two files and write data to second file using awk
Hi Guys,

I wanted to compare a delimited file and positional file, for a particular key files and if it matches then append the positional file with some data.

Example:

Delimited File
--------------
Code:
Byer;Amy;NONE1;A5218257;E5218257
Byer;Amy;NONE1;A5218260;E5218260

Positional File
--------------
Code:
190004000153E5218257010000000980002425852013
190004000153E5218258010000003850002425852013
190004000153E5218259010000012190002425852013
190004000153E5218260010000003850002425852013
190004000153E5218261010000012190002425852013

If the fifth filed in the delimited file is found in the positional file at position 13 then we have to append the fourth field from the delimited file into the positional file, at the end of the respective record.

Expected output
===============
Code:
190004000153E5218257010000000980002425852013A5218257
190004000153E5218258010000003850002425852013
190004000153E5218259010000012190002425852013
190004000153E5218260010000003850002425852013A5218260
190004000153E5218261010000012190002425852013

Script Used
===========
Code:
awk 'BEGIN{FS = ";"};FNR==NR{A[$5] = $4}
FNR!=NR{if ((x = substr($0,13,8)) in A) print $0 A[x];else print A[x]}' $1 $2 > $3


The above awk command is not working properly. It is not appending the desired data in the positional file.

Please help.

Thanks in advance!!

Thanks,
Ajay

locale::script

Locale::Script(3perl)					 Perl Programmers Reference Guide				     Locale::Script(3perl)

NAME

       Locale::Script - standard codes for script identification

SYNOPSIS

	  use Locale::Script;

	  $script  = code2script('phnx');		      # 'Phoenician'
	  $code    = script2code('Phoenician'); 	      # 'Phnx'
	  $code    = script2code('Phoenician',
				 LOCALE_CODE_NUMERIC);	      # 115

	  @codes   = all_script_codes();
	  @scripts = all_script_names();

DESCRIPTION

       The "Locale::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924
       four-letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying scripts. The ones currently supported are:

       alpha
	   This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician.

	   This code set is identified with the symbol "LOCALE_SCRIPT_ALPHA".

	   The Zxxx, Zyyy, and Zzzz codes are not used.

	   This is the default code set.

       numeric
	   This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician.

	   This code set is identified with the symbol "LOCALE_SCRIPT_NUMERIC".

ROUTINES

       code2script ( CODE [,CODESET] )
       script2code ( NAME [,CODESET] )
       script_code2code ( CODE ,CODESET ,CODESET2 )
       all_script_codes ( [CODESET] )
       all_script_names ( [CODESET] )
       Locale::Script::rename_script  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Script::add_script  ( CODE ,NAME [,CODESET] )
       Locale::Script::delete_script  ( CODE [,CODESET] )
       Locale::Script::add_script_alias  ( NAME ,NEW_NAME )
       Locale::Script::delete_script_alias  ( NAME )
       Locale::Script::rename_script_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Script::add_script_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Script::delete_script_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes man page.
