NAME
clamz - download MP3 music files from Amazon.com
SYNOPSIS
clamz [
options ]
amz-file ...
DESCRIPTION
clamz is a little command-line program to download MP3 files
from Amazon.com's music store. It is intended to serve as a
substitute for Amazon's official MP3 Downloader, which is not free
software (and therefore is only available in binary form for a limited
set of platforms.)
clamz can be used to download either
individual songs or complete albums that you have purchased from
Amazon.
In order to use clamz, you must first enable the ``MP3 dowloader
mode'' by visiting the following URL:
-
http://www.amazon.com/gp/dmusic/after_download_manager_install.html?AMDVersion=1.0.9
If you are outside the US, replace `amazon.com' with the corresponding
domain for your country (e.g., amazon.co.uk for the UK, or amazon.fr
for France.) Amazon does not allow anyone to purchase MP3 files from
outside their country of residence.
To download the contents of an AMZ file into the current directory,
just run
-
clamz some-file-name.amz
More advanced options are listed below.
OPTIONS
- -o name-format, --output=name-format
-
Set the name of the downloaded file(s). This may contain any of
several variables which are derived from the input AMZ file; see
FORMAT VARIABLES below. Note that the format string should be
enclosed in single quotes, to stop the shell from expanding variables
itself.
- -d directory-format, --output-dir=directory-format
-
Set the directory where the downloaded files should be placed. (If
this directory does not exist, it will be created.) This may also
contain format variables.
- -r, --resume
-
Resume downloading a partially-downloaded album. (By default, if you
are downloading a file named foo.mp3, and the file foo.mp3 already
exists in the destination directory, clamz will rename the new
file to foo.mp3.1 to avoid overwriting the old file. If the -r
option is used, clamz will instead assume that the first part of
the file has already been downloaded, and will resume downloading from
where it left off.)
- -i, --info
-
Rather than downloading anything, just display detailed information
about the given AMZ file(s) to standard output.
- -x, --xml
-
Rather than downloading anything, print the raw, decrypted XML data
from the AMZ file to standard output.
- -v, --verbose
-
Display detailed information while downloading.
- -q, --quiet
-
Turn off the normal progress display; display only error messages.
- --forbid-chars=characters
-
Do not allow the given characters to be used in output
filenames. Note that control characters and slashes may never be used
in filenames.
- --allow-chars=characters
-
Opposite of the above; remove the given characters from the set
of disallowed characters.
- --allow-uppercase
-
Allow uppercase letters in filenames.
- --forbid-uppercase
-
Do not allow uppercase letters in filenames.
- --utf8-filenames
-
Use UTF-8 when writing filenames (the default behavior is to use UTF-8
if the system locale says so, otherwise ASCII.)
- --ascii-filenames
-
Use only ASCII characters in filenames.
- --help
-
Print out a summary of options.
- --version
-
Print out version information.
FORMAT VARIABLES
As part of a
name-format or
directory-format option, you
may include references to environment variables (e.g.,
$HOME) or
to the `xdg-user-dirs' configuration variables (e.g.,
$XDG_MUSIC_DIR or
$XDG_DESKTOP_DIR.)
In addition, the following special variables are defined for each track,
based on the information provided in the AMZ file, and subject to the
above configuration options (--forbid-chars,
--forbid-uppercase, etc.)
- ${title}, ${creator}, ${tracknum}, ${discnum}, ${genre}, ${asin}
-
Title, creator, track number, disc number, genre, and ASIN (Amazon
Standard Identification Number) of each individual track.
- ${album}, ${album_artist}, ${album_asin}
-
Title, primary artist, and ASIN of the album the track comes from.
(This information is available both for single-track and full-album
downloads.)
- ${suffix}
-
Suffix of the output file (currently only `mp3'.)
- ${amz_title}, ${amz_creator}, ${amz_genre}, ${amz_asin}
-
These variables formerly contained metadata for the AMZ file as a
whole; current AMZ files do not contain this information. Using these
variables is not recommended.
Similar to shell variable expansion, you can also use the following
conditional expressions:
- ${var:-string}
-
Expands to the value of variable var if it is defined and
non-empty; otherwise, expands to string (which may itself
contain variable references.)
- ${var:+string}
-
Expands to string if the variable var is defined and
non-empty; otherwise, expands to an empty string.
Note that when you include format variables in a command-line
argument, you will usually need to enclose the argument in single
quotes ('...'), or insert a backslash before the `$', to prevent the
shell from trying to expand the variables itself.
