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>

TAG FORMAT

   See http://www.xiph.org/vorbis/doc/v-comment.html for documentation  on
   the  Ogg Vorbis tag format, including a suggested list of canonical tag
   names.
