Help needed in some unix commands
Hi,
Solutions may be in ksh or bash
1. i have some files like.
Code:
CAT_CO00102_20100816190955.Z   CAT_CO00102_20100816190955Q.Z  CAT_CO00202_20100825135947A.Z

to find out files ends with A.Z or Q.Z i use following in ksh.
Code:
 
CAT="CAT*[A|Q].Z"
ls $CAT
CAT_CO00102_20100816190955Q.Z  CAT_CO00202_20100825135947A.Z

i want to find out files which don't have A.Z or Q.Z in the end using ls command?

2. i define a function outside the nawk command which trims the leading and trailing spaces like
Code:
  function TrimSpace(x)
  {
    y=gsub(/^[ \t]+|[ \t]+$/,"",x)
    {
      return x
    }
  }

and i want to call this function in nawk commad like.
Code:
nawk '{print TrimSpace($1)}' file

Note: this function works fine if i define it within nawk.You may use your any dumy function for testing.
If it is possible to any outside function in nawk? and if yes,how to accomplish it

3. Sometimes while unziping some files i got an error and the further unziping stopped.might be other files are able to be unzip.i.e
Code:
 
gunzip a.Z b.Z c.Z 
gunzip: a.Z: unexpected end of file

it found an error on a.Z and stopped but b.Z and C.Z might be correct.
why this error comes and is there any possible way to skip the file with error and let the others start to unzip.

Advance thanks

locale::codes::langext

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

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.
