Complex string operation (awk, sed, other?)
I have a file that contains RewriteRules for 200 countries (2 examples for 1 country below):

Code:
RewriteRule ^/at(/|/index.html|)$ http://%{HTTP_HOST}/locate/index.html?locale=de_AT [R=301,L]

#&

RewriteRule ^/at_english(/|/index.html|)$ http://%{HTTP_HOST}/locate/index.html?locale=en_AT [R=301,L]

I have another list of redirects for the mobile versions of these sites in the following format:
Code:
RewriteRule ^/at_engilsh(/|/index.html|)$ http://%{HTTP_HOST}m.website.com/www.website.com/at_engilsh [R=301,L]

Bear in mind the at_english is just 1 of the country codes, there are many more.

So my goals is to go from

Code:
RewriteRule ^/at_english(/|/index.html|)$ http://%{HTTP_HOST}/locate/index.html?locale=en_AT [R=301,L]

#to

RewriteRule ^/at_engilsh(/|/index.html|)$ http://%{HTTP_HOST}m.website.com/www.website.com/at_engilsh [R=301,L]

I'm supplying the awk / pseudo code for one way I've thought to do it.

Code:
awk '
{
newurl="m.website.com/www.website.com/"
one=substr($0,1,14)
two=substr($1,13,37)
rest=substr($4,1)

# The line below this comment is the section I'm having difficulty with because 
#I have country codes in multiple formats at / at_engilsh / at_french
#I want to select all characters between ^/ ---> (  
code=substr($2,1) 
     

printf ("%s%s%s%s%s %s\n", one,code,two,newurl,code, rest)
}' input

So I either need help converting the pseudo code into actual code, or suggestions on a better way to do this operation.

Thank you for any help

locale::country

Locale::Country(3pm)					 Perl Programmers Reference Guide				      Locale::Country(3pm)

NAME

       Locale::Country - standard codes for country identification

SYNOPSIS

	  use Locale::Country;

	  $country = code2country('jp' [,CODESET]);	   # $country gets 'Japan'
	  $code    = country2code('Norway' [,CODESET]);    # $code gets 'no'

	  @codes   = all_country_codes( [CODESET]);
	  @names   = all_country_names();

	  # semi-private routines
	  Locale::Country::alias_code('uk' => 'gb');
	  Locale::Country::rename_country('gb' => 'Great Britain');

DESCRIPTION

       The "Locale::Country" module provides access to several code sets that can be used for identifying countries, such as those defined in ISO
       3166-1.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 3166-1
       two-letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying countries. 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:

	  $country = code2country('jp','alpha-2');
	  $country = code2country('jp',LOCALE_CODE_ALPHA_2);

       The codesets currently supported are:

       alpha-2, LOCALE_CODE_ALPHA_2
	   This is the set of two-letter (lowercase) codes from ISO 3166-1, such as 'tv' for Tuvalu.

	   This is the default code set.

       alpha-3, LOCALE_CODE_ALPHA_3
	   This is the set of three-letter (lowercase) codes from ISO 3166-1, such as 'brb' for Barbados. These codes are actually defined and
	   maintained by the U.N. Statistics division.

       numeric, LOCALE_CODE_NUMERIC
	   This is the set of three-digit numeric codes from ISO 3166-1, such as 064 for Bhutan. These codes are actually defined and maintained
	   by the U.N. Statistics division.

	   If a 2-digit code is entered, it is converted to 3 digits by prepending a 0.

       fips-10, LOCALE_CODE_FIPS
	   The FIPS 10 data are two-letter (uppercase) codes assigned by the National Geospatial-Intelligence Agency.

       dom, LOCALE_CODE_DOM
	   The IANA is responsible for assigning two-letter (uppercase) top-level domain names to each country.

ROUTINES

       code2country ( CODE [,CODESET] )
       country2code ( NAME [,CODESET] )
       country_code2code ( CODE ,CODESET ,CODESET2 )
       all_country_codes ( [CODESET] )
       all_country_names ( [CODESET] )
       Locale::Country::rename_country	( CODE ,NEW_NAME [,CODESET] )
       Locale::Country::add_country  ( CODE ,NAME [,CODESET] )
       Locale::Country::delete_country	( CODE [,CODESET] )
       Locale::Country::add_country_alias  ( NAME ,NEW_NAME )
       Locale::Country::delete_country_alias  ( NAME )
       Locale::Country::rename_country_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Country::add_country_code_alias	( CODE ,NEW_CODE [,CODESET] )
       Locale::Country::delete_country_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.

       alias_code ( ALIAS, CODE [,CODESET] )
	   Version 2.07 included 2 functions for modifying the internal data: rename_country and alias_code. Both of these could be used only to
	   modify the internal data for country codes.

	   As of 3.10, the internal data for all types of codes can be modified.

	   The alias_code function is preserved for backwards compatibility, but the following two are identical:

	      alias_code(ALIAS,CODE [,CODESET]);
	      rename_country_code(CODE,ALIAS [,CODESET]);

	   and the latter should be used for consistency.

	   The alias_code function is deprecated and will be removed at some point in the future.

	   Note: this function was previously called _alias_code, but the leading underscore has been dropped. The old name was supported for all
	   2.X releases, but has been dropped as of 3.00.
