Thank you everyone for the help.

I'm one step closer to finishing the script.

---------- Post updated at 11:18 AM ---------- Previous update was at 11:05 AM ----------

Actually sorry, I spoke too soon. I should have explained a little more clear

My source file is more like this
Code:
Time, 9/1/11, 9/2/11 .. 9/30/11
0:00, 1033, 1031, .. 1035
0:10, 1044, 1045, .. 1046
...
23:50, 1050, 1051, .. 1052

How do I make it so the file will be like this?
Code:
9/1/11, 0:00, 1033
9/1/11, 0:10, 1044
...
9/1/11, 23:50, 1050
9/2/11, 0:00, 1031
9/2/11, 0:10, 1045
....
9/2/11, 23:50 1052
..
9/30/11, 00:00, 1050
9/30/11, 00:10, 1045
..
9/30/11, 23:50, 1052

I tried doing something like this,
Code:
i=0
while [ $i -lt ${#TRACK[*]} ]
 do

  for n in {2..144}
   do
    cat $WORKING/${TRACK[i]}.csv |awk -F ',' '{print$1 "," $'$n'}' > tmp00
    awk -F "," 'NR==1{x=$'$n';next} {sub("^",x",")}1' tmp00 
  done

 i=$(( $i + 1 ))
done

I'm getting good results with the first date (sept 1, 11), however once it's sept 2, 11, I get only a blank at the front of the line.
e.g.,
Code:
09/01/11,23:20,1551
09/01/11,23:30,1556
09/01/11,23:40,1506
09/01/11,23:50,1480
,0:00,1455
,0:10,1401
,0:20,1382
,0:30,1309

How do I get the $n variable into awk -F "," 'NR==1{x=$'$n';next} {sub("^",x",")}1' properly?

Any help is appreciated.

Thank you

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.
