As far as permissions, I’d do something like this from the /share/flash/data directory:
chown -R admin:everyone mp3
find mp3 -type d exec chmod 2775 {} ;
find mp3 -type f exec chmod 664 {} ;
I tried this and got the following back:
# cd /share/flash/data
# chown -R admin:everyone mp3
find mp3 -type d exec chmod 2775 {} ;
# find mp3 -type d exec chmod 2775 {} ;
find: paths must precede expression
Usage: find [path...] [expression]
# … so not sure what’s missing here, but I’m not too worried – I can now dump files into the /mp3/iTunes Music folder so at least I’m back in business in that respect…
