Hi Don,

I tried using :

sed -e 's/^"/^B/' -e 's/"$/^B/' -e 's/",/^B,/g' -e 's/,"/,^B/g' -e 's/"//g' -e 's/^B/"/g'
but i could see that all the double quotes are replaced by
^B
and also eliminating the last double quote in the data file.

Input:

Code:
   221100,37.20,"C","0073/1454","44019120","16395","16395/14103000","Safety   Workwear - "Screwfix","","Screwfix Direct   Ltd","10/10/2014","2520",""

Output:

Code:
   ^B221100^B,37.20,^BC^B,^B0073/1454^B,^B44019120^B,^B16395^B,^B16395/14103000^B,^BSafety   Workwear - Screwfix^B,^B^B,^BScrewfix Direct Ltd^B,^B10/10/2014^B,^B2520^B,^B

Expected Output:

Code:
   221100,37.20,"C","0073/1454","44019120","16395","16395/14103000","Safety   Workwear - Screwfix","","Screwfix Direct   Ltd","10/10/2014","2520",""

If you can see in the output , the last column with null value has been replaced only with a single double quote.

Please help me to resolve this issue.

Regards,
Lavanya.

locale::script

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

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. The ones currently supported are:

       alpha
	   This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician.

	   This code set is identified with the symbol "LOCALE_SCRIPT_ALPHA".

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

	   This is the default code set.

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

	   This code set is identified with the symbol "LOCALE_SCRIPT_NUMERIC".

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 man page.
