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

       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>

       -a, --append
              Updates 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.

       -d 'name[=value]', --rm 'name[=value]'
              Specify a tag on the command line for removal. 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. If no value is given
              all tags are deleted with the given name. Otherwise only those with matching values are deleted.

       -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.
