Let me check. Okay, a couple of things. First, for the copy command, make sure that you don't include a trailing slash for the source directory, otherwise it copies the contents of the directory and not the directory itself. So: pclmills# cp -r COPYME ~james/ NOT: pclmills# cp -r COPYME/ ~james/ This will set the group permission correctly, not the user, and the permissions are in accordance with umask. So the result of the above copy is: [james@pclmills ~]$ ls -l | grep COPYME drwxr-xr-x 2 root james 512 Oct 28 11:03 COPYME And the file inside the directory gets: [james@pclmills ~]$ cd COPYME/ [james@pclmills ~/COPYME]$ ls -l total 0 -rw-r--r-- 1 root james 0 Oct 28 11:03 file As you've got configuration scripts, if your umask is the same as mine then this should be fine. It's reasonably trivial, of course, to add a line to the copy script to use chmod and chown to change the permissions as you want them to be changed. the $dir variable in the above for loop contains the name of the home directory. If this is the same name as the UID/GID (which it is by default) then even though it looks weird something like: chown -R $dir:$dir /usr/home/$dir/$maildir will get you close. Of course, remember this warning from man chown: -R Change the user ID and/or the group ID of the specified directory trees (recursively, including their contents) and files. Beware of unintentionally matching the ``..'' hard link to the parent directory when using wildcards like ``.*''. How I do something like this is to build the script one line at a time using test directories that I set up. Do that first and everything should be tickety boo. I put the mailing list's address back in the cc line of this email; use "reply all", not reply, to hit the whole mailing list and have people who are *far* better scripters than me chime in with helpful hints ;) James
