VORBISCOMMENT(1)               Ogg Vorbis Tools               VORBISCOMMENT(1)

       vorbiscomment - List or edit comments in Ogg Vorbis files

       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]

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

       -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

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

       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

       the Ogg Vorbis tag format, including a suggested list of canonical tag
