NAME

       vorbiscomment - List or edit comments in Ogg Vorbis files

SYNOPSIS

       vorbiscomment [-l] [-R] [-e] file.ogg
       vorbiscomment -a [ -c commentfile | -t “name=value” ] [-q] [-R] [-e] in.ogg [out.ogg]
       vorbiscomment -w [ -c commentfile | -t “name=value” ] [-q] [-R] [-e] in.ogg [out.ogg]

DESCRIPTION

       vorbiscomment Reads, modifies, and appends Ogg Vorbis audio file metadata tags.

OPTIONS

       -a, --append
              Append comments.

       -c file, --commentfile file
              Take  comments  from a file. The file is the same format as is output by the the -l
              option or given to the -t option: one element per line in  'tag=value'  format.  If
              the file is /dev/null and -w was passed, the existing comments will be removed.

       -h, --help
              Show command help.

       -l, --list
              List the comments in the Ogg Vorbis file.

       -q, --quiet
              Quiet mode.  No messages are displayed.

       -t 'name=value', --tag 'name=value'
              Specify  a  new  tag on the command line. Each tag is given as a single string. The
              part before the '=' is treated as the tag name and the part after as the value.

       -w, --write
              Replace comments with the new set given either on the command line with -t or  from
              a  file  with  -c. If neither -c nor -t is given, the new set will be read from the
              standard input.

       -R, --raw
              Read and write comments in UTF-8, rather than converting to  the  user's  character
              set.

       -e, --escapes
              Quote/unquote  newlines and backslashes in the comments. This ensures every comment
              is exactly one line in the output (or input), allowing  to  filter  and  round-trip
              them.  Without it, you can only write multi-line comments by using -t and you can't
              reliably distinguish them from multiple one-line comments.

              Supported escapes are c-style "\n", "\r", "\\" and "\0". A  backslash  followed  by
              anything else is an error.

              Note:  currently, anything after the first "\0" is thrown away while writing.  This
              is a bug -- the Vorbis format can safely store  null  characters,  but  most  other
              tools wouldn't handle them anyway.

       -V, --version
              Display the version of vorbiscomment.

EXAMPLES

       To just see what comment tags are in a file:

           vorbiscomment -l file.ogg

       To edit those comments:

           vorbiscomment -l file.ogg > file.txt
           [edit the comments in file.txt to your satisfaction]
           vorbiscomment -w -c file.txt file.ogg newfile.ogg

       To simply add a comment:

           vorbiscomment -a -t 'ARTIST=No One You Know' file.ogg newfile.ogg

       To add a set of comments from the standard input:

           vorbiscomment -a file.ogg
           ARTIST=No One You Know
           ALBUM=The Famous Album
           <ctrl-d>
