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::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.
