> Here is what I have:

> 
> /home/compsci/user1
> /home/compsci/user2
> /home/compsci/user3

> Now this worked for me last year, and as equiv to root I

> each folder to mark.  But it took some time to go into each folder 
> individually, looking for assignments

> Here is what I would like:

> directory structure like so   
> 
> /homework/compsci
> /homework/saps
> /homework/7a
> 
> one directory for each class, but no individual user folders inside.

> I want to give the kids responsibility to "hand-in" their assignments 
> into the appropriate folders.  BUT:

> I don't want other classes to be able to mess with their files.  so 
> compsci kids can't mess with saps files, etc.  But I wanted

> further and say that the compsci kids could hand in their 
> finished work 
> into the /homework/compsci folder, but not delete or change the file 
> once it is there
> 
> in other words I want the class homework folders to have write once 
> access/no read access/and no delete access.  So they can 
> save/drop the 
> file into the directory, but not change it or delete it once there
> 
> So after that long preamble, what rights do I set on a folder to 
> acomplish this?  You should know that each class has a 
> distinct gid so I 
> can set rights using that, I think

> I am thinking, if the rights can be set like I want, that

> their completed assignments into the appropriate homework 
> "dropbox" and 
> they are done, and can't cheat off of, or trash, other 
> classmate's files
