...what an interesting question. 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/
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
[james at 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 at pclmills ~]$ cd COPYME/
[james at pclmills ~/COPYME]$ ls -l
-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
trees (recursively, including their contents) and files.
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
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 ;)
