Transpose with two newlines as delimiter
Hi Guys,

I have data in a file as follows:

Code:
 
a 1 2 3
b 4 5 6 
 
 
a 6 7 8 
 
 
a 4 7 9 
b 6 8 5 
c 0 8 7

So the number of rows which have data is variable (2 for the first group, one for the second group and three for the third group), but the delimiters between the groups is always two newlines.

I want something like this:

Code:
a b c 
1 4 0
6 6
4

I tried the following transpose with awk and it is giving me:
Code:
 
a 1 2 3         b 4 5 6          a 6 7 8     a 4 7 9           b 6 8 5         c 0 8 7

There are tabs between different groups. Here is the awk statement I am using:

Code:
 
$ awk ' BEGIN {FS="\n\n"} { for (i=1;i<=NF;i++) { arr[NR,i]=$i; if(nf<= NF) nf=NF; } nr=NR } END { for(i=1;i<=nf;i++) { for(j=1;j<=nr;j++) { printf("%s\t",arr[j,i]); } printf("\n"); } }' try.txt > try1.txt

Any ideas what may be wrong?

Thanks.

locale::codes::langvar

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

NAME

       Locale::Codes::LangVar - standard codes for language variation identification

SYNOPSIS

	  use Locale::Codes::LangVar;

	  $lvar = code2langvar('acm');		       # $lvar gets 'Mesopotamian Arabic'
	  $code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langvar_codes();
	  @names   = all_langvar_names();

DESCRIPTION

       The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, 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 variations. 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:

	  $lvar = code2langvar('en','alpha-2');
	  $lvar = code2langvar('en',LOCALE_CODE_ALPHA_2);

       The codesets currently supported are:

       alpha
	   This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian.

	   This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA".

	   This is the default code set.

ROUTINES

       code2langvar ( CODE [,CODESET] )
       langvar2code ( NAME [,CODESET] )
       langvar_code2code ( CODE ,CODESET ,CODESET2 )
       all_langvar_codes ( [CODESET] )
       all_langvar_names ( [CODESET] )
       Locale::Codes::LangVar::rename_langvar  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangVar::add_langvar  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangVar::delete_langvar  ( CODE [,CODESET] )
       Locale::Codes::LangVar::add_langvar_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangVar::delete_langvar_alias  ( NAME )
       Locale::Codes::LangVar::rename_langvar_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangVar::add_langvar_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangVar::delete_langvar_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
