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.
