hi rbatt,

I have tried this below code

Code:
awk '{if($2=$4) print $5="MATCHED" ; else print $5="NOTMATCHED"}' UDC_STG_COMP > UDC_STG_COMP1

But output is not as expected.

Coming to your question.

Is this homework/assignment? There are specific forums for these.

Code:
No homework. Actually i have two big files and i have parse them into one single file using below awk command. But now stuck at this point where i need to match these two column. its part of almost done assignment. with its solution this will done.

Code:
awk '
FNR==NR {a[$1] = $0
          next
         }

         {print $0, a[$1]?a[$1]:"NA"
         }
 ' FS=, STG3_DATA UDC_DATA > UDC_STG_COMP

What have you tried so far?

i have tried this below

Code:
awk '{if($2=$4) print $5="MATCHED" ; else print $5="NOTMATCHED"}' UDC_STG_COMP > UDC_STG_COMP1

What output/errors do you get?

The output is not as desired..

Code:
$ awk '{if($2=$4) print $5="MATCHED" ; else print $5="NOTMATCHED"}' UDC_STG_COMP > UDC_STG_COMP1

eshaqur@IN00106004 ~/MNP_PRE_CUTOVER_AUDIT
$ head -n 10 UDC_STG_COMP1
NOTMATCHED
NOTMATCHED
NOTMATCHED
NOTMATCHED
NOTMATCHED
NOTMATCHED
NOTMATCHED

What OS and version are you using?

Code:
Windows and trying this awk script in linux environment

What are your preferred tools, if not just awk? (C, shell, perl, awk, etc.)

Code:
awk will be good because i am learning same as well.. if not shell,perl will be ok.

thanks for your showing interest and helping me. Looking forward for solution if you can provide me. it will be really greatful

locale::codes::langext5.18

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.
