Hello Junaid,

Just want to add here on Scott's comment, Cron has an own reserved syslog facility, so you should have a look into /etc/syslog.conf (or the equivalent file in your distro) to see where messages of facility cron are sent. Also you can check /var/spool/mail/user_name too for same. Let us know is this helps.


EDIT: Also while checking your script I found out that line if diff $TMP $TMP_FILE >/dev/null
I think what you are trying to do here to, not to display the differance in standard output, this command will redirect output to /dev/null so each time condition will be FALSE and if I am right here then you can use following then.

Here is an example which I have tested for same.
Input files:
Code:
cat chumm1
test test1
test
 
cat chumm2
test test1
test20


Now check this following command out.
Code:
if [[ -z $(diff chumm1 chumm2 2&>1 /dev/null)
then
       echo "There are differances.";
else
       echo "there is nothing";
fi

Output will be as follows.
Code:
There are differances.

Also why can't you go for a variable named email_users="x@chumma.com y@chumma.com z@chumma.com .

Code:
echo "Error occurred on `hostname`
        $ERROR
 * This is an auto-generated email *
        " | /bin/mailx -r "noreply@company.com" -s "Error occurred on `hostname`" $email_users < $ERROR

Could you please try same and let us know if that helps.


Thanks,
R. Singh

locale::codes::langext

Locale::Codes::LangExt(3)				User Contributed Perl Documentation				 Locale::Codes::LangExt(3)

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

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

	  $lext = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
