If you want files to have the same group owner as the directory then you can set the group sticky bit (chmod g+s), if the folder is not world writeable then the user has to be a member of that group (secondary or primary), I can't think how you can allow users to write files into a folder without them having permissions to create subfolders.

If you have a directory /export/foo with a subdirectory called bar:
1. You want users to be able to create files in foo.
2. Only root may create files in bar.
3. Users to be able to only read/list/access files in bar.
4. Files in bar have the only read/execute permissions for non-root users.
then:

Code:

# chown root:groupname /export/foo
# chmod 1770 /export/foo
# chmod g+s /export/foo
# chown root:root /export/foo/bar
# chmod 750 /export/foo/bar
# chmod g+s /export/foo/bar

The umask for the root account will need to be 027 and its primary group should be root or else it should run "newgrp root" before creating files in /export/foo/bar.
I am assuming all your users requiring access to this folder will be in a common group (called groupname in this example ).

sticky bit

as far as i understand, if sticky bit is set on a directory, the files created under tht directory cannot be deleted by ordinary user... but we can do ths by permission itself,,, tht's assign only read permission to tht dirrectory wht 's the difference?
