NAWK conversion of hexadecimal input to decimal output via printf, I am close I can feel it
I have searched and the answers I have found thus far have led me to this point, so I feel I am just about there.

I am trying to convert a column of hexadecimal to decimal values so that I can filter out via grep just the data I want. I was able to pull my original 3 character hex value and append 0x to the front but the printf statement seems not to work to convert it to decimal. I dumped my output to a file and have been trying to get it to convert so I can proceed on.

Here are the last lines snipped from my file, as it it large:


Code:
0x0C0,###0,33,6291
0x011,###1,59,0
0x009,###0,59,362147
0x011,###2,59,260
0x00E,###2,59,1051
0x008,###1,33,0
0x034,###2,59,0
0x001,###3,59,208
0x00E,###2,33,52
0x034,###2,33,0
0x00F,###1,59,0
0x009,###0,33,33022

From the shell prompt I tried:

Code:
printf  "%d\n" 0x03E

and get the proper output:

62

If I type:

Code:
cat <file>|nawk -F, '{printf "%d\n" , $1}'

I get nothing but zeroes as output:


Code:
0
0
0
0
0
0
0
0
0


I tested via:

Code:
cat <file>|nawk -F, '{$1,"     ""%d\n",$1}'

and my output has the correct output from $1, but "%d\n" won't output the decimal equivalent:


Code:
0x0C0     0
0x011     0
0x009     0
0x011     0
0x00E     0
0x008     0
0x034     0
0x001     0
0x00E     0
0x034     0
0x00F     0
0x009     0



So what am I missing? I have had it suggested that printf is different in awk than in the shell but that seemed wrong from what I read.

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.
