Sadly, setting / comparing with value seems to be an issue for my approach:
Code:
	$AWK '/^#/ { next } ;
	{ 
		bitrate=$3+$4;
		len=( length(bitrates) ); print len
		len = length(bitrates)  ; print len
		ext="kb"; if(len >= 4) ext="mb"; 
		if(len >= 4) bitrates=(substr(bitrates,3));

		split($2, A, "x");
		pixels=A[0] * A[1];
		
		print "\t* "BOLD$1RESET,$2 "   ",pixels,$3,$4,bitrate ext,$5,$6" "$7" "$8" "$9" "$10" "$11" "$12" "$13" "$14" "$15;
		
	}' BOLD="\033[1m" RESET="\033[0m" UNDERLINE="\033[4m" OFS="\t" "$PRESETS"

  1. While i do see now 'kb' for all the bitrates, it neither changes to mb when bitrate is 5120, nor does it cut 3 numbers from the string.
  2. Is there a better way o display the whole comment, rather than " "$7" "$8" "$9" "$10" "$11" "$12" "$13" "$14" "$15 to preseve words?
  3. pixels are still empty, and would require the same 'handling' as the bitrates.

len is always 0, so that is why the check doesnt work, but how to fix that please?

Thank you

ncdt

NcdT(1) 						      General Commands Manual							   NcdT(1)

NAME

       ncdt - directory tree printer with extended capabilities

SYNOPSIS

       ncdt [-db?]  [--dirs] [--bitrate] [--prefix text ] [--help] [ directory [ name ]]

DESCRIPTION

       ncdt is a small utility for printing directory trees. It has some additional features not found in tree(1). Additional capabilities are:

       -      size field for directories displays the summary size of directory subtree instead of the size of the special file (which is somewhat
	      more useful)

       -      sizes are displayed in a more readable format (that's a minor improvement, but it helps a little)

       -      MP3 files are detected; additional info is displayed for them (which is probably the nicest thing about NcdT) The info is  displayed
	      in  a  compact form, like <2:53 v168JR+> where 2:53 is play time, v (if present) means the file is encoded using VBR, 168 is bitrate
	      (average bitrate for VBR files), J describes channel encoding (Mono, Stereo, Joint-Stereo, Dual channel), R (if present)	means  the
	      file  has  a  RIFF header at the beginning, + (if present) means the file has ID3v2 tag attached - (if present) means there's no ID3
	      tag at all (none of these means there's only ID3v1 tag present).

       NcdT is particularily nice for indexing CDs.

OPTIONS

       -d --dirs
	      Print only directories, omit files. This mode is a rough equivalent of du(1).

       -b --bitrate
	      Print bitrate info for directories. Bitrates are displayed both for ordinary files and directories. If all  MP3  files  in  a  given
	      directory subtree have the same bitrate only one number is printed, if they have various bitrates the range is printed.

       --prefix text
	      Prefix listing with given text. This option is not intended for general use.  It might be used by programs using NcdT to index CDsor
	      doing similar operations to record additional information.

       -? --help
	      Display usage summary.

USAGE

       When called without any parameters ncdt displays directory tree for current directory (.).

       When called with one parameter ncdt displays directory tree for specified directory.

       When called with two parameters ncdt displays directory tree for the directory specified as its first parameter.  Second parameter is  used
       as directory label for the top level directory (instead of directory name from parameter 1).

EXAMPLES

       ncdt   prints directory tree for the current directory. It will be labeled .

       ncdt /usr
	      prints directory tree of /usr. It will be labeled /usr

       ncdt /cdrom 'CD #21'
	      prints directory tree of /cdrom. It will be labeled CD #21

       ncdt -db /cdrom
	      lists directory sizes, play times and bitrate ranges

SEE ALSO

       tree(1), du(1)

BUGS

       NcdT uses quite a lot of memory. It's also not very fast, but on a decent CPU it should not be noticeable.

       There are no real bugs I'm aware of. I don't think there are any now.
