I have a bunch of long-running scripts and applications that are storing output results in a directory shared amongst a few users. I would like a way to make sure that every file and directory created under this shared directory automatically had u=rwxg=rwxo=r permissions.

I know that I could use umask 006 at the head off my various scripts, but I don't like that approach as many users write their own scripts and may forget to set the umask themselves.

I really just want the filesystem to set newly created files and directories with a certain permission if it is in a certain folder. Is this at all possible?

Update: I think it can be done with POSIX ACLs, using the Default ACL functionality, but it's all a bit over my head at the moment. If anybody can explain how to use Default ACLs it would probably answer this question nicely.

What is "umask" and how does it work?

I believe that umask is something that controls file permissions, but do not fully understand it. After running umask 0644 in a terminal, I cannot read the files I create with the command-line text editor nano.
