Vorbiscomment

Write tags to a file

vorbiscomment -l speech01.ogg > speech01.meta

Same as ..

vorbiscomment -c speech01.meta speech01.ogg

File to tags

To take the contents of a text file (in the same format as the output comment -l)... and update the tags in the audio file, use -c and -w:

vorbiscomment -c speech01.meta -w speech01.ogg

<DANGER!>: without -w the command does the opposite, taking the current tags *from* the ogg file and rewriting the .meta file:

Editing tags in a file

So altogether...

vorbiscomment -l speech01.ogg > speech01.meta
nano speech01.meta
vorbiscomment -c speech01.meta -w speech01.ogg
