how can i get a file or directory to be owned by two people? (have read/write permissions) i understand this involves groups, so i added user
www-data to group
user, then did
chown www-data:user dir
but i am not getting the effect i want.
more details: all my web projects are rooted in drop box. i work in a windows environment, change files, and 10s later they're updated on the linux machine via dropbox. for directories/files that need write access, i do:
chown www-data:www-data dir
BUT then dropbox loses the ability to update that file, i think it's because
user is no longer an owner of that file.
