Script to get checksum of itself

is there a way to get a script to do a checksum on itself?

something like this:

Code:
#!/bin/sh

myexpectedsig=$(cksum $0 | awk '{print $1}')
if [ ${myexpectedsig} -ne 83373373737 ] ; then
     exit
else
   who
   uptime
   date
fi

im looking for something that would always represent the running script, which is why im using "$0" above. but $0 may not be reliable. as in, it may not always refer to the running script file.

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.
