Chksum on two directories then copy if they are not identical or existing
How can I have an intelligent script that will copy from source to destination directory if the file doesnt exist there or the chksum is not match.

Code:
SOURCE directory: 

 for i in `ls`
> do
> echo $i
> md5sum $i
> echo ""
> done
asdasda
00039a616135792fb609d04cf27aed95  asdasda

chksums
5053d1886cbb9a9c5e9399bbc187d030  chksums

zunauthftp.vf6
00039a616135792fb609d04cf27aed95  zunauthftp.vf6

zunauthimap.vf6
6b1815b8f75b651916549dafb5fa347c  zunauthimap.vf6

zunauthpop.vf6
8589e73b814c1241b1c2c887340f711a  zunauthpop.vf6

zunauth.vf6
5590c0992a894493ca126123aa958a2e  zunauth.vf6

zunauweb.vf6
64c5ca1dc4582da68818adae80507c8c  zunauweb.vf6

Code:
Destination:

for i in `ls`
> do
> echo $i
> md5sum $i
> echo ""
> done
chksums
5053d1886cbb9a9c5e9399bbc187d030  chksums

zunauthftp.vf6
00039a616135792fb609d04cf27aed95  zunauthftp.vf6

zunauthimap.vf6
6b1815b8f75b651916549dafb5fa347c  zunauthimap.vf6

zunauthpop.vf6
8589e73b814c1241b1c2c887340f711a  zunauthpop.vf6

zunauth.vf6
5590c0992a894493ca126123aa958a2e  zunauth.vf6

zunauweb.vf6
125993721bfdcc9f8de614a182da0a01  zunauweb.vf6

Code:
In this case, file asdasda(not existing) and zunauweb.vf6(different chksum) should be copied to the destination directory.

locale::codes::langvar

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.
