sed command working different in linux environment.
Hi
I tried running the code
Code:
scrname=`whence $0 | sed -e 's/\.\///g'`

where $0 is substituted by cm_dsjobrun.sh
in unix env then the value it returns me is

SCRNAME=/data/ds/dpr_ebicm_uat/etl/cm3_0/scripts/shell/cm_dsjobrun.sh

whereas i ran the same code on linux env

The value its returning me as in scrname as ''

I am not able to figure out why this is happening, could you all please help me. What changes should i make in the command so that it will return me the same output as it is giving in unix enviornment i.e .
Code:
SCRNAME=/data/ds/dpr_ebicm_uat/etl/cm3_0/scripts/shell/cm_dsjobrun.sh

Please help

Thanks.

I read on the whence command one point i would like to share is it detects it detects commands and aliases, and searches your path.
So my script path is searched properly in unix env... whereas this is not happening in the linux enviornment.
Could you all please help me in modifying the command so that i get the exact path of my script.

---------- Post updated at 11:35 PM ---------- Previous update was at 07:09 AM ----------

HI

To get the path in linux i tried
Code:
scrname={PWD}/$0

Where $0 will be script name.

My question is if i am using PWD instaed of whence in linux what difference it can cause to my script.

Thanks

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.
