vorbiscomment

VORBISCOMMENT(1)						 Ogg Vorbis Tools						  VORBISCOMMENT(1)

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