NAME

       id3 - an ID3 tag editor.

SYNOPSIS

       id3 [-tTaAycg newdata] file1 [file2 [file3...]]
       id3 -l file1 [file2 [file3...]]
       id3 -d file1 [file2 [file3...]]
       id3 -L

DESCRIPTION

       id3 is an ID3 v1.1 tag editor. ID3 tags are traditionally put at the end of compressed streamed audio files to denote information about the
       audio contents. Up to thirty characters of Title, Artist, and Album information can be stored, as well as  a  28-character  comment,  four-
       digit year, track number up to 255, and an enumerated genre.

OPTIONS

       -t title
	      Sets the title tag to the first 28 characters of title.

       -T track
	      Sets the track tag to a number between 0 and 255.

       -a artist
	      Sets the artist tag to the first 28 characters of artist.

       -A album
	      Sets the album tag to the first 28 characters of album.

       -y year
	      Sets the year tag to the first 4 characters of year.

       -c comment
	      Sets the comment tag to the first 28 characters of comment.

       -g genre
	      Sets the genre number tag using a genre number or predefined genre label.

       -l     List/view the ID3 tag.

       -L     List all genre tags.

       -R     Use rfc822-style output for tag printout.

       -d     Delete the ID3 tag.

BUGS

       The  ID3  format has some shortcomings. There is a 1 in 16777216 chance of your mp3 having a certain bit-pattern, causing id3 to write over
       the last 128 bytes of your mp3 upon tag creation. If you add a track number to an ID3 v1.0 tag, the last  two  characters  of  the  comment
       string will be truncated. Any bugs found in id3 should be forwarded to the author, Robert Woodcock <rcw@debian.org>.
