Comparing sizes in percentages of 2 files in bash
Hi guys, I hope you can enlight me with a script I'm doing for Solaris 10.
Script goes like this:

Code:
#!/usr/bin/bash
fechahoy=`perl /export/home/info/John/fechamod.pl`
fechayer=`perl /export/home/info/John/fecha.pl`

echo $fechahoy
echo $fechayer
DAT1=`ssh ivt@blahblah ls -la /export/home/ivt/inventory/Services_$fechahoy* | awk -F" " {'print $5'}`
DAT2=`ssh ivt@blahblah ls -la /export/home/ivt/inventory/Services_$fechayer* | awk -F" " {'print $5'}`

Script uses another perl script who outputs date as YYYYMMDDHHMMSS (ex. 20110425151745)
Well, then I put ls -la to calculate the size of yesterday's file, and today's file.

Problem is I don't know how to compare the size of yesterday's file ($fechayer) to today's file ($fechahoy) and then, if the difference of the size is 20% less than yesterday, abort script with error.

What would be the algorithm for calculating that difference of size in percentage?

if fechahoy<fechayer by more than 20% --->then abort


Hope you help me, thanks a lot!

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.
