Each of the files consisted of 7 columns: the first three columns are the same in each file and the other 4 columns are the actual data (but we need to use only the last three of those). The merging would mean to keep the first three columns and then add the the last three columns of each file matched by the first column. For example, infile1 could be

Code:
a b c 1 2 3 4
d e f 5 6 7 8
g h j 9 10 11 12

infile2 could be:

Code:
a b c 11 3 4 5 
g h j 9 8 7 6
d e f 1 2 3 4

infile3 could be

Code:
d e f 2 3 4 5
a b c 5 6 7 8
g h j 9 10 11 12



then the after the merging step1, the outfile1 would look like like this:

Code:
a b c 1 2 3 4 3 4 5
d e f 5 6 7 8 2 3 4
g h j 9 10 11 12 8 7 6

then after adding infile3, the outfile2 would look like this:

Code:
a b c 1 2 3 4 3 4 5 6 7 8
d e f 5 6 7 8 2 3 4 3 4 5
g h j 9 10 11 12 8 7 6 10 11 12

I hope this clears things up.

Many thanks!

locale::codes::langext

Locale::Codes::LangExt(3)				User Contributed Perl Documentation				 Locale::Codes::LangExt(3)

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.
