How to get the latest and new values from the file in perl?
Hi,

I have a file with these following contents..

Code:
StartTimeStamp,EndTimeStamp,Counter1,Counter2,Counter3,Counter4
Aug13 2010 02:49:21,Aug13 2010 02:54:21,9,8,0,0
Aug13 2010 02:59:32,Aug13 2010 03:00:00,0,0,0,0
Aug13 2010 03:00:00,Aug13 2010 03:04:32,9,8,0,0
Aug13 2010 03:07:55,Aug13 2010 03:08:55,0,0,0,0

I am not able to get the last value and current value.

After some process the above file gets appended with new count vaule...

Now the recent contents of the file are:

Code:
StartTimeStamp,EndTimeStamp,Counter1,Counter2,Counter3,Counter4
Aug13 2010 02:49:21,Aug13 2010 02:54:21,9,8,0,0
Aug13 2010 02:59:32,Aug13 2010 03:00:00,0,0,0,0
Aug13 2010 03:00:00,Aug13 2010 03:04:32,9,8,0,0
Aug13 2010 03:07:55,Aug13 2010 03:08:55,0,0,0,0
Aug13 2010 04:07:55,Aug13 2010 04:08:55,1,0,0,0
Aug13 2010 04:10:55,Aug13 2010 04:13:55,2,0,0,0

I have to compare the value before and after run i.e just check the values in file before running and after some process those values get incremented.

I have to compare those values.

How can i do it perl?




Any suggestions?

Regards

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.
