DESCRIPTION

id3
mass tagger is a tool for manipulating id3 and id3v2 tags in multiple files. It can generate tag fields from the filename and other variables, and/or rename files, using an intuitive syntax.

id3 currently supports the old-style ID3 format with track-number extension (ID3 v1.1), as well as the more complicated ID3v2 (ID3 v2.2.0, v2.3.0) format. This also means use is pretty much limited to audio files which use these formats, e.g, MPEG-1 Layer III.

OPTIONS

Order of the options is only important where specified.
filespec ...
specifies the file(s) to be affected by the command.

If you use wildcards, it is STRONGLY recommended to enclose the specification in double quotes (""). id3 has internal shell pattern matching which will not work if your shell also performs this function.

The shell pattern matching can be applied to both file names and directory names.

-h
show commandline help
-V
display version number and copyright
-v
be verbose
-M
preserve last modification time of files operated on
-1
process/add ID3v1 tags (default).
-2
process/add ID3v2 tags.
-3
process/add Lyrics3 tags.

If more than one tag type is specified, they are all written, but only the left-most tag is read from. If no tag type is specified, this is equivalent to `-1 -3E'.

-d
do not re-use existing tag data. If no new tag information is specified in conjunction with this option, all selected tags will be removed.

-t title
-a artist
-l album
-n tracknr
-y year
-g genre
-c comment

add/replace the specified fields in all selected tags with the values given. Field values are scanned for substitution variables, see SUBSTITUTION below. If a field value is a single variable, and its substitution fails, no operation is performed.
Genres can be specified either directly or with their assigned number, regardless of tag format.
-f filename-template
rename files encountered according to filename-template. The argument is scanned for substitution variables. An empty variable will by default get replaced with ``Unknown''. Trying to rename to an already existing file will cause an error.
-q format
for each file encountered, format will get scanned for substitution variables, and written to standard output. Using this option will block any attempt to modify files.
-m
match mode; interpret any variables found in a filespec as a wildcard, and set the tag field corresponding to the matched wildcard. Thus, `-m "%a - %t.mp3"' is equivalent for `-a %1 -t %2 "* - *.mp3"'. This option is merely a shorthand and does not add any intelligence; in particular, any variable interpreted still counts as a wildcard, see SUBSTITUTION below.
-D filename
duplicate and copy the tags of the specified format as found in filename to the target files. The tag in each file is replaced after any variables have been read, but before any fields are updated.

Any original tag values not explicitly copied to the new tag (for example, by using -u) are lost. If filename does not have any tags, this option is identical to the -d option.

-R
searches recursively; Normally, path seperators in filespec do not get matched by `?' or `*' wildcards. With this switch, they are treated as an ordinary character.
--
force the following argument to be interpreted as a filename. Use this for files that start with a `-' (dash). SUBSTITUTION below.

The following options only apply on the tag most recently selected before them, and only have meaning where relevant.

-u
update all standard tag fields by copying them from the source tag. This is similar to writing `-talnygc %t %a %l %n %y %g %c', but only operates on the most recent tag. It is possible for the source and destination tag to be the same.
-E
only write a tag of the selected type if a file already contains it; do not add new ones. If `-3' is not specified, this is the default behaviour for Lyrics3 tags.
-s size
try to write a new tag using exactly size bytes, adding / removing padding as necessary. The resulting tag will have no padding if size is smaller than the actual size necessary.
-rFRAME
remove all occurrences of frames named FRAME from the tag. Consult the format documentation for valid FRAME names.
-wFRAME data
add / update a frame named FRAME with data in the tag. data is scanned for substitution variables. Again, consult the format documentation. See COMPATIBILITY for more information.

Individual options can be stacked in a single argument for more convenience. For example, running


   id3 -2d -alt "Artist" "Album" "Title" *.mp3

is equivalent to:


   id3 -2 -d -a "Artist" -l "Album" -t "Title" *.mp3

SUBSTITUTION

id3 can perform ``printf-like'' substitution on the values prior to writing them to a tag. Note that if you want to use pattern matching, you HAVE TO enclose the wildcard specification on the commandline in double quotes to prevent your shell from expanding any wildcards.
\c
escape sequence. \n, \r, \t, \v, \f, \b, \a, get replaced as in C, any other character will be stripped of any special meaning. E.g., \n becomes the newline character, \\ a single backslash.
%<modifiers>N
where N <- [0..9] replaced with the portion of the file path matching the nth `*' (asterisk) wildcard in the file specification. 0 is taken to mean 10.
%<modifiers>c
where c <- [a..z]
replaced by values according to the following table:
%t title
%a artist
%l album title
%n track number
%y year
%g genre
%c comment field
%f file name (without path)
%p path to filename
%x auto-increasing counter
%X file counter
Values get read (where applicable) from the source tag, which is the left-most tag selected on the command line, and reflect the state of the file before any modifications were made. If the source value is not available, the variable fails. %p%f combines to the full path and file name. The %x value gets increased every time it has been substituted inside the same directory, and is intended for auto-numbering. %X increases for every file processed.
%%
replaced with a single ``%'', equivalent to \%
%|text||alt text||...|?
substituted by the first text that was completely successful, or fails as empty, see fall-backs below. This can be used as an all-or-nothing substitution. A lone ``%?'' always fails.

Available <modifiers> (optional):

+ (plus sign)
Capitalize the substituted value
- (minus sign)
Convert all characters to lowercase
_ (underscore)
Use the raw value of the variable. Normally, substitution replaces any underscores with spaces, and condenses empty whitespace.
* (asterisk)
Split the variable into seperate words by looking at the capitalization.
# (hash or pound sign)
Pad all numeric values within the substituted value, if necessary. Multiple hash signs can be stacked to increase desired width. If there are no numeric values, this modifier has no effect.
|fall-back|
If substitution for a variable fails, attempt fall-back instead. fall-back itself may be empty or contain other variables (including other fall-backs). If fall-back contains variables that fail, the fall-back fails and will not be used. If more than one fall-back is provided, successive fall-backs are tried until one succeeds.

EXAMPLES

Here are some examples of using id3:
id3 -a "Stallman" -t "Free Software Song" fs_song.mp3"
Add a simple tag to a file.
id3 -d *.mp3
Removes all ID3v1 tags from all mp3's.
id3 -2 -1u fs_song.mp3
Copy ID3v2 tag to ID3v1 tag in selected file.
id3 -D source.mp3 -1 -2 dest.mp3
Duplicate ID3v1 and ID3v2 tags of source.mp3
id3 -a "TAFKAT" -n "%1" -t "%+2" "*. *.mp3"
Update tag fields similar to this; 
   -a "TAFKAT" -n "01" -t "My Song"  "01. my_song.mp3"
   -a "TAFKAT" -n "02" -t "Untitled" "02. untitled.mp3"
id3 -2 -f "%a - %t.mp3" blaet.mp3
Rename file to a standard format, using ID3v2 values.
id3 -a %t -t %a "*.mp3"
Swap artist and title fields in all mp3's.
id3 -2 -rAPIC -s 0 *.mp3
Removes embedded images and padding from all mp3's.
id3 -2d -u *.mp3
Rewrite ID3v2 tag while keeping only the basic fields.
id3 -2 -wUSLT "foo, baralala! blaet.mp3
Adds an ID3v2 lyric frame to blaet.mp3.
id3 -v -g alt-rock -alnt "The Author" %1 %2 %3 "Author - */(*) *.mp3"
Process multiple directories at once.
id3 -v -g alt-rock -a "The Author" -m "Author - %l/(%n) %t.mp3"
Shorthand for the previous example.
id3 -2 -c "Was: %_f" -f "%|Nobody|a - %|Untitled (%x)|t.mp3" "*.mp3"
Advanced rename. Saves previous filename in the comment field.
id3 -2 -q "%| %a - %|Untitled|t || %t || %1 |?" "*.mp3"
Generate a playlist.
 

NOTES

The internal pattern matching emulates the normal pattern matching of ``sh''. It supports ?, * and [].

A shell pattern will never match a forward slash (``/'') or a dot (``.'') beginning a filename. Wildcards can be used for directories as well (to arbitrary depths), in which case a search will be performed.

In an ambiguous situation, the pattern matcher will always resolve a ``*'' wildcard to the shortest possible sequence of tokens. This differs from the behavior of regular expressions, however it tends to make sense in the context of filenames.

Do NOT add ID3 tags to files for which it does not make sense, i.e, add them only to MP3 files. In particular, do not add ID3v2 tags to Ogg files, since ID3v2 tags start at the beginning of the file.

COMPATIBILITY

id3 has a built-in genre list of 148 genres. If you pass the -g parameter a string instead of a number when using ID3v1, id3 tries to find the specified genre in this list, and selects the closest possible match (if any). For the genre numbers and exact spelling, see id3v1.c in the source distribution. An empty or invalid genre is assigned the number 0.

id3 automatically writes Unicode tags where necessary. Depending on your system, you may only be able to fully work with all characters if you are using an UTF-8 locale.

id3 will write the ID3v2 tag version that was encountered and does not convert from one version to another. If no existing tag is found, ID3 v2.3 will be written (this may change in a future version).

The -wFRAME parameter only knows the following ID3v2.2 (3 letter)/ID3v2.3 (4 letter) frames: T??/T??? (text), W??/W??? (links), COM/COMM (comment), IPL/IPLS (involved people), ULT/USLT (lyrics), CNT/PCNT (numeric play counter) and USER (tos, v2.3 only). Frames that do not match the tag type encountered are ignored and not converted. It is a no-op for ID3v1.

id3 does not (currently) support ID3v2 v4.0 tags. It also does not support ID3v2 features as compression, encryption, ...
