How to lowercase the values in a column in awk and include a dynamic counter?
Hi,
I am trying to incorporate 2 functions into my `awk` command.
I want to lower case Column 2 (which is essentially the same information in Col1, except in Col1 I want to maintain the capitalization) and I want to count from 0-N that begins and ends with the start of certain markers that I have.

The data (tab-separated) currently looks like this:

Code:
<s>
He	PRP	-
could	MD	-
tell	VB	-
she	PRP	-
was	VBD	-
teasing	VBG	-
him	PRP	-
.	.	.
</s>
<s>
He	PRP	-
kept	VBD	-
his	PRP$	-
eyes	NNS	-
closed	VBD	-
,	,	-
but	CC	-
he	PRP	-
could	MD	-
feel	VB	-
himself	PRP	-
smiling	VBG	-
.	.	.
</s>

The ideal output would be like this:

Code:
<s>
He	he	PRP	1
could	could	MD	2
tell	tell	VB	3
she		she	PRP	4
was	was	VBD		5
teasing	teasing	VBG	6
him	him	PRP	7
.	.	.	8
</s>
<s>
He	he	PRP	1-
kept	kept	VBD	2
his	his	PRP$	3
eyes	eyes	NNS	4
closed	closed	VBD	5
,	,	,	6
but	but	CC	7
he	he	PRP	8
could	could	MD	9
feel	feel	VB	10
himself		himself	PRP	11
smiling	smiling	VBG	12
.	.	.	13
</s>

The 2-step `awk` that I am trying that does not work is this:

Step 1:
Code:
awk '!NF{$0=x}1' input | awk '{$1=$1; print "<s>\n" $0 "\t.\n</s>"}' RS=  FS='\n' OFS='\t-\n' > output

Here, I do not know how to make the "-" into a counter

and Step 2 (which directly gives me an error):
Code:
awk '{print $1 "\t" '$1 = tolower($1)' "\t" $2 "\t" $3}' input > output

Any suggestions 1. on how to solved the lower and counter and 2. if it is possible to combine these two steps?

Thank you in advance

locale::codes::langfam

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.
