My shell script that I have so far is

Code:
top_veg_cost=$(cat -n Thanksgiving/Loaded_Mashed_Potatos/Ingredients.csv Thanksgiving/Meat_Loaf/Ingredients.csv Thanksgiving/Pumpkin_Pie/Ingredients.csv | grep vegatable)

echo "$top_veg_cost"

out come I have so far is

Code:
     1  Potato,vegatable,0.89,5
     4  green_onion,vegatable,0.99,3
    11  onion,vegatable,0.89,2
    12  bell_pepper,vegatable,0.89,2
    21  pumpkin_pie_filling,vegatable,2.98,1

when I add a sort command to the script like this

Code:
top_veg_cost=$(cat -n Thanksgiving/Loaded_Mashed_Potatos/Ingredients.csv Thanksgiving/Meat_Loaf/Ingredients.csv Thanksgiving/Pumpkin_Pie/Ingredients.csv | grep vegatable | sort -t, +2 -3n)

echo "$top_veg_cost"

new out come is

Code:
    11  onion,vegatable,0.89,2
    12  bell_pepper,vegatable,0.89,2
     1  Potato,vegatable,0.89,5
     4  green_onion,vegatable,0.99,3
    21  pumpkin_pie_filling,vegatable,2.98,1


I have no idea what command I should add to get the 2 highest cost vegetables which are

Code:
 21  pumpkin_pie_filling,vegatable,2.98,1 
  4  green_onion,vegatable,0.99,3

I might even need to change what I have just not sure

locale::script

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

NAME

       Locale::Script - standard codes for script identification

SYNOPSIS

	  use Locale::Script;

	  $script  = code2script('phnx');		      # 'Phoenician'
	  $code    = script2code('Phoenician'); 	      # 'Phnx'
	  $code    = script2code('Phoenician',
				 LOCALE_CODE_NUMERIC);	      # 115

	  @codes   = all_script_codes();
	  @scripts = all_script_names();

DESCRIPTION

       The "Locale::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924
       four-letter codes will be used.

SUPPORTED CODE SETS

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

	  $script = code2script('phnx','alpha');
	  $script = code2script('phnx',LOCALE_SCRIPT_ALPHA);

       The codesets currently supported are:

       alpha, LOCALE_SCRIPT_ALPHA
	   This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician.  It also includes additions to this set
	   included in the IANA language registry.

	   The Zxxx, Zyyy, and Zzzz codes are not used.

	   This is the default code set.

       num, LOCALE_SCRIPT_NUMERIC
	   This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician.

ROUTINES

       code2script ( CODE [,CODESET] )
       script2code ( NAME [,CODESET] )
       script_code2code ( CODE ,CODESET ,CODESET2 )
       all_script_codes ( [CODESET] )
       all_script_names ( [CODESET] )
       Locale::Script::rename_script  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Script::add_script  ( CODE ,NAME [,CODESET] )
       Locale::Script::delete_script  ( CODE [,CODESET] )
       Locale::Script::add_script_alias  ( NAME ,NEW_NAME )
       Locale::Script::delete_script_alias  ( NAME )
       Locale::Script::rename_script_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Script::add_script_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Script::delete_script_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
