Audiotag

REQUIREMENTS To use Audiotag, you must have:

1. Perl >= 5.6
2. At least one of...
   - id3tag and id3info (from id3lib, id3lib.sourceforge.net) in $PATH
   - vorbiscomment (from vorbis-tools, xiph.org/ogg/vorbis) in $PATH
   - metaflac (from flac, flac.sourceforge.net) in $PATH

INSTALL Just copy `audiotag' to /usr/local/bin (or somewhere in your $PATH)

USAGE % audiotag [OPTION]... [FILE]...

tip: Always use the -p option before running it for real!

Examples:

Set GENRE to "Metal"
% audiotag -g Metal *.mp3 *.ogg

Guess and set TRACKNUM - guess track uses the simple pattern '(\d\d)'
% audiotag -G *.mp3 *.ogg

Set TITLE based on a pattern match of the filename - This example would
work for files with a name in the form "Mudvayne - 01. Shadow of a Man.ogg"
% audiotag --title-pattern '.*?\d\d\. (.*?)\.ogg' *.ogg

Same as above, but don't really do anything, just see what it WOULD do
% audiotag --pretend --title-pattern '.*?\d\d\. (.*?)\.ogg' *.ogg

Rename files based on their meta-data, so the filenames are in the form:
"TRACKNUM. Artist (Album Name) Song Title.ogg"
eg. "02. Tool (Undertow) Prison Sex.ogg"
% audiotag --rename-files --rename-pattern '%t. %a (%A) %s' *.ogg

BUGS - comment field support isn't fully functional for MP3s, because, for some reason, comment fields in MP3s are key/value pairs... which doesn't translate to ogg and flac. And id3tag doesn't support MP3 comment fields very well to begin with either.

- the --rename-files option will fail(ungracefully) if illegal filename
  characters are in a track's meta-data, eg. '/' on *nix(and most other
  systems), or '\' on 'doze(but who cares?).
