This is a common misunderstanding about permissions and the Unix philosophy about them, which is: It's up to the user, not the system, to say what permissions he wants on new filesystem objects. Modifing the user's umask is not advised, as this is global. *Every* new file or dir then ends up with g+w and you probably don't want that. You need to use Posix ACLs for this, and your file system and kernel must support them; you configure it per directory. It's all in man pages and on google - better start reading. Be warned though: you *will* forget you set this, and *will* wonder in future why g+w is set in various places. "ls" gives precious little clue that an ACL is in place. I find that in real life, a "find -exec chmod" in a cron is a better solution -- alan dot mckinnon at gmail dot com
