If the above pipe-line throws an error, let us know what system are you using.
Wow, that is an educating command for me. Smilie
I use Ubuntu 10.10 and this doesn't give an error, but it doesn't work properly either.

First it found nothing in my test directory, which contains one mp3 album and a flac album.
That was expected because all tags were filled. Well not really expected, because there is only tested on id3 tags and my Flac files don't have id3 tags. So with the command above I should expect to show all my flac files. metatag should be used for
But all mp3 tags were filled. So I changed that. I emptied a title from one track, renamed another track to 'track' and another one to 'unknown'.

I would expect to show these 3 files, but when I tried again, he found 2 files. None of those were changed. He found 1 allright mp3 track and 1 allright flac track.

Strange, isn't it?

Ah... I tested some more and it looks like there isn't tested on an empty tag so it's correct that only two tracks are found, but there seems something wrong with the order of the tracks in the stream so I get 2 random files as output.

So to be perfected the command should be extended with the following:
- mp3 files should be tested with id3, flac with metaflac
- empty tracks should be recognised as well, where only spaces count as empty
- if an mp3 file has no id3 tag or a flac has no FLAC Vorbis tag I think it can be counted empty as well. But that is probably to hard to include that restriction in just one commandline. It's a minor.
- and last but not least: the right files should be reported.

And now I'm going to try to understand what you did in that commandline. It looks very interesting. Smilie
Maybe I'll can figure it out now before you do. Who knows.

I like the dirty trick t(itle|rack)|a(rtist|lbum) although it's 2 actually characters more than title|track|artist|album, it is a nice demonstration of the possibilities.

NAME
id3ren - Reads and writes ID3 tags from mp3 files. SYNOPSIS
id3ren [-help] [-song=SONG_NAME] [-artist=ARTIST_NAME] [-album=ALBUM_NAME] [-year=YEAR] [-genre={# | GENRE}] [-comment=COMMENT] [-track=TRACK] [-showgen] [-searchgen={# | GENRE}] [-default=DEFAULT] [-copytagfrom=FILE [-copysong] [-copyartist] [-copyalbum] [-copyyear] [-copygenre] [-copycomment] [-copytrack] [-copyall] ] [-quick] [-noalbum] [-nocomment] [-noyear] [-nogenre] [-notrack] [-tag] [-edit] [-notagprompt | -showtag | -striptag | -tagonly] [-nocfg] [-log] [-quiet] [-verbose] [-defcase | -lower | -upper] [-remchar=CHARS] [-repchar=CHARS] [-space=STRING] [-tagfromfilename | -tagffn] [-tagtemplate=TAGTEMPLATE] [-template=TEMPLATE] [FILE1 FILE2.. | WILDCARDS] COPYRIGHT
id3 Renamer (C) Copyright 1998 by Robert Alto (badcrc@tscnet.com) (C) Copyright 2001 Christophe Bothamy (cbothamy@free.fr) DESCRIPTION
id3ren is used to rename batches of mp3 files by reading the ID3 tag at the end of the file which contains the song name, artist, album, year, and a comment. The secondary function of id3ren is a tagger, which can create, modify, or remove ID3 tags. OPTIONS -album ALBUM_NAME Sets the album name to use when tagging files. All files will be tagged with this album name without prompting. -album=ALBUM_NAME Sets the album name to use when tagging files. All files will be tagged with this album name without prompting. -artist=ARTIST_NAME Sets the artist name to use when tagging files. All files will be tagged with this artist name without prompting. -comment=COMMENT Sets the comment to use when tagging files. All files will be tagged with this comment without prompting. -copyalbum Copies the album field from the source file tag set by -copytagfrom -copyall Copies all the fields from the source file tag set by -copytagfrom -copyartist Copies the artist field from the source file tag set by -copytagfrom -copycomment Copies the comment field from the source file tag set by -copytagfrom -copygenre Copies the genre field from the source file tag set by -copytagfrom -copysong Copies the song field from the source file tag set by -copytagfrom -copytagfrom=FILE Sets the filename to copy tag field from. -copytrack Copies the track field from the source file tag set by -copytagfrom -copyyear Copies the year field from the source file tag set by -copytagfrom -defcase Use the default case of characters from the ID3 tag when renaming files. This is default. -default=DEFAULT Sets the default field to be used only when renaming if a field is blank. Useful when renaming and creating "unknown" subdirecto- ries. Defaults to "unknown". -edit If a file already has a tag and you want to change just one specific field of the tag, use this option in conjunction with -tag and the option for the field you want to change. For example to change just the album name of a file: id3ren -tag -edit -album="New Album Name" sample.mp3 * This option is a toggle. -genre=# | GENRE_NAME Sets the genre to use when tagging files. All files will be tagged with this genre without prompting. To see a list of allowable genres use the -showgen argument. -genre accepts either the number of the genre as displayed with -showgen, or the name of the genre. -help Displays the help screen. -log Log most output to id3ren.log. * This option is a toggle. -lower Convert file names to lowercase characters. -noalbum Don't prompt for the album when adding a tag. * This option is a toggle. -nocfg Don't try reading any config files, even if they exist. * This option is a toggle. -nocomment Don't prompt for a comment when adding a tag. * This option is a toggle. -nogenre Don't prompt for a genre when adding a tag. * This option is a toggle. -notagprompt Never prompt for tag information. Files without tags are skipped. * This option is a toggle. -notrack Don't prompt for the track number when adding a tag. * This option is a toggle. -noyear Don't prompt for the year when adding a tag. * This option is a toggle. -quick Automatically sets -noalbum, -nocomment, and -noyear. -quiet Run quietly, displaying only errors or prompts. * This option is a toggle. -remchar=CHARS CHARS indicates a string of characters that will be removed from the filename if found. -repchar=CHARS CHARS indicates a string of characters, EACH followed by the character to replace it with. For example, to replace all plus '+' signs with a hyphen all '&' with '_', you would use '-repchar +-&_'. -searchgen=# | GENRE Searches the list of genres and displays either the genre name corresponding to #, or shows all substring matches of GENRE. -showgen Displays all the music genres currently in the program. -showtag Display the tags for the specified files. No renaming is performed. -song=SONG_NAME Sets the song name to use when tagging files. All files will be tagged with this song name without prompting. -space=PSTRING Change all spaces in the renamed file to STRING. To remove all spaces, use -striptag Remove the tags for the specified files. * This option is a toggle. -tag Always ask for a tag, even if the file already has one. * This option is a toggle. -tagfromfilename, -tagffn Use informations from the filename when tagging. See tagtemplate. * This option is a toggle. -tagonly Don't rename any files, just ask for tag information. Note that -tagonly only asks for tag information on files that don't have a tag already. To have it ask for a tag on all files, use with -tag. * This option is a toggle. -tagtemplate=TEMPLATE Use TEMPLATE as the basis for tagging files. The default template used is '[%a]-[%s].mp3'. Identifiers that can be used in the template are: %a - Artist name %c - Comment %s - Song name %t - Album title %n - Track Number %y - Year %g - Genre %d - Dummy It is a VERY good idea to have fixed separators between fields. -template=TEMPLATE Use TEMPLATE as the basis for renaming files. The default template used is '[%a]-[%s].mp3'. Identifiers that can be used in the template are: %a - Artist name %c - Comment %s - Song name %t - Album title %n - Track Number %y - Year %g - Genre -track=TRACK Sets the track number to use when tagging files. All files will be tagged with this track number without prompting. TRACK must be an integer between 1 and 99. -upper Convert file names to uppercase characters. -verbose Display more messages than usual. * This option is a toggle. -year=YEAR Sets the year to use when tagging files. All files will be tagged with this year without prompting. And of course the program accepts wildcards for filenames. FILES
