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 -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. -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
