# ncdt(1)

directory tree printer with extended capabilities

## 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)](/tree/1.md). 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)](/du/1.md).

- **-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)](/tree/1.md), [du(1)](/du/1.md)

## 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.
