Hello cola,

Could you please try following and let me know if this helps you.
Solution 1st: To get by 2nd field in code.
Code:
awk '{print $2}'   Input_file

Solution 2nd: Considering your Input_file has only 2 fields so getting the last field of it then.
Code:
awk '{print $NF}'   Input_file

Solution 3rd: Using cut command for this task may help too.
Code:
cut -d" " -f2   Input_file

Thanks,
R. Singh

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

NAME
Locale::Codes::LangVar - standard codes for language variation identification SYNOPSIS
use Locale::Codes::LangVar; $lvar = code2langvar('acm'); # $lvar gets 'Mesopotamian Arabic' $code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm' @codes = all_langvar_codes(); @names = all_langvar_names(); DESCRIPTION
The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, 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 variations. 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: $lvar = code2langvar('en','alpha-2'); $lvar = code2langvar('en',LOCALE_CODE_ALPHA_2); The codesets currently supported are: alpha This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian. This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA". This is the default code set. ROUTINES
code2langvar ( CODE [,CODESET] ) langvar2code ( NAME [,CODESET] ) langvar_code2code ( CODE ,CODESET ,CODESET2 ) all_langvar_codes ( [CODESET] ) all_langvar_names ( [CODESET] ) Locale::Codes::LangVar::rename_langvar ( CODE ,NEW_NAME [,CODESET] ) Locale::Codes::LangVar::add_langvar ( CODE ,NAME [,CODESET] ) Locale::Codes::LangVar::delete_langvar ( CODE [,CODESET] ) Locale::Codes::LangVar::add_langvar_alias ( NAME ,NEW_NAME ) Locale::Codes::LangVar::delete_langvar_alias ( NAME ) Locale::Codes::LangVar::rename_langvar_code ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangVar::add_langvar_code_alias ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangVar::delete_langvar_code_alias ( CODE [,CODESET] ) These routines are all documented in the Locale::Codes::API man page.
