I partially agree with you, but give me nice shellcode to use in
a script with xargs (because of find -print0 | xargs -0) that can
(a) change e.g. the ARTIST value
(b) add a new name=value pair, but not if it already exists.
The only way I was able to do these two is:
(a) for i in `find . -name something`; do
vorbiscomment -l $i | sed -e 's/(ARTIST=).*/\1new_value/' | \
vorbiscomment -w $i
done
(b) for i in `find . -name something`; do
(vorbiscomment -l $i | grep -v NAME; echo NAME=VALUE) | \
vorbiscomment -w $i
done
Neither is xargs usable, and the second even has to spawn a subshell.
With id3, both would be possible in a single xargs-compatible line.
