Filter record from a file
Reposting since I didnt not get any reply.

I have a problem while filtering records from a file. Can somebody help please?

For eg: Consider the below files
Record file:
Code:
0003@00000000000190@20100401@201004012010040120100401@003@
0003@00000000000200@20100329@201003292010032920100329@003@
0003@00000000000550@20100401@201004012010040120100401@048@
0003@00000000000910@20100401@201004012010040120100401@017@
0004@00000000001401@20100328@201003282010032820100328@300@
0004@00000000001401@20100401@201004012010040120100401@010@
0004@00000000001431@20100401@201004012010040120100401@010@
0005@00000000001441@20100329@201003302010033020100330@300@
0005@00000000001830@20100328@201004012010040120100401@300@
0005@00000000002080@20100329@201003292010032920100329@003@

Filter File:
Code:
0004@300@20100328@20100329
0005@300@20100328@20100329

Code:
awk -F\@ 'NR==FNR{f[$1,$3,$5];next}($1SUBSEP$3SUBSEP$2 in f) {print $0}' $Record $Filter

This will not work since we are comparing 1st position to 1st, 3rd to 3rd and 5th to 2nd.

But if the filter file was like below this code would have worked.

Code:
 awk -F\@ 'NR==FNR{f[$1,$3,$5];next}($1SUBSEP$3SUBSEP$5 in f) {print $0}' $Record $Filter

Code:
0004@300@20100328@20100329@300
0005@300@20100328@20100329@300

Could somebody help me to figure out how we can make the first process work?

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.
