Thanks,Scrutinizer, Corona, Yoda First 3 worked.. to list all files NOT starting with a :




# Worked well: Seems matching is passed to ls command: " ls -l [!a]bc "
Code:
# ls -l ab[c]
-rw-------   1 useradm    users            0 Mar 27 12:57 abc


# ls -l [!a]bc
-rw-------   1 useradm    users            0 Mar 26 15:27 bbc

# Worked well: Seems matching is passed to shell.
Code:
# echo [!a]bc 
bbc

This is too worked fine, seems matching is done through shell.
Code:
# ls -l !(a)+(bc)
-rw-------   1 useradm    users            0 Mar 26 15:27 bbc
-rw-------   1 useradm    users            0 Mar 26 15:27 bbcabc
-rw-------   1 useradm    users            0 Mar 26 15:27 bbcbbc

Yoda, thanks for the manual page,

Don thanks for pointing out the difference of use when "shell uses filename pattern matching" & when "Regular expression uses pattern matching".
Is there a way we can figure out which is shell doing, and which is doing by regular expressions.


For example with the below example: How to figure out which portion is shell or regex performing the operation:

Code:
# ls -l bbcbbc
-rw-------   1 useradm    users            0 Mar 26 15:27 bbcbbc


# ls -l !([c-z])?[c][b][b][b-d]
-rw-------   1 useradm    users            0 Mar 26 15:27 bbcbbc


echo $SHELL
/usr/bin/ksh
#OS= hp-ux 11.23


Thanks..

locale::codes::langfam5.18

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME

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

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. 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 = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
