vorbiscomment - List or edit comments in Ogg Vorbis files
vorbiscomment [-l] [-R] [-e] file.ogg
vorbiscomment Reads, modifies, and appends Ogg Vorbis audio file
-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.
Show command help.
List the comments in the Ogg Vorbis file.
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.
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.
Read and write comments in UTF-8, rather than converting to the
user's character set.
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 "
", "\" and " ". A
backslash followed by anything else is an error.
Note: currently, anything after the first " " 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

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
