Being new to the UNIX world I was hoping someone could help me with a file/directory permissions question. I have a folder that I want to give one group (Graphic Artists) full read and write permissions and another group (Copywriters) only read access. Is there a way to do this under OS X Server? I've looked up information in a couple UNIX websites last night but it made it sound like I couldn't do this. I know this is possible under NT/2000. Any help would be greatly appreciated.

I was looking for ways to do the same thing, and have *also* found nothing. Perhaps I am not being creative enough in my thought process...

Let me know if you do happen to find out something..

You can assign privileges in a number of ways under OS X.

The question really is how to organize the privileges. Whoever creates the folder is the owner, the owner has unlimited read/write/execute privileges, unless otherwise inhibited by the system admin. There is also a group associated with every folder or file, most often it is the top-most group to which the owner belongs, but it can be changed or left open, below that is everybody else, for which you can block access entirely or give simple read only permissions. In the case of needing to set two groups with different permissions, the easiest thing to do is create a link. You can then block everyone access for both folders, set the group for the real folder to the one which gets read/write access, then set the group on the link to the one that gets read only access, leaving the owner the same for both.

To do this:

Log on as the admin user.
Open a Terminal session.
Type % <BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>sudo -s</font>[/code]
Enter the admin password
Navigate to the directory level which contains the folder.
Type # <BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>ls -l</font>[/code]
Review the current folder privileges (owner & group)
Type # <BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>ln -s ./name_of_folder/ ./name_of_link_folder/</font>[/code]
The -s attribute creates a symbolic link as opposed to a hard link.
Now type # <BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>chgrp -R -h name_of_read only_group ./name_of_link_folder</font>[/code]
Type # <BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>exit</font>[/code]

That should be it. Now you can use the Privileges tab from the command-I window to set the permissions.
