Restricting Permissions

I'm having some odd behavior with some folders that appear to be hidden in finder, but show up when logged into the command line. Sample output:

Code:

Code:
ls -lah
drwxrwxr-x  10 administ  allorion   340B 16 Aug 06:14 *More old folders, work
drwxrwxr-x  20 administ  allorion   680B 30 Mar  2006 *OLD Spring 2004
drwxrwxr-x  10 administ  allorion   340B 16 Aug 06:14 *OLD volume 3
drwxrwxr-x  12 administ  allorion   408B 26 Aug 06:23 .
drwxrwxr-x  27 administ  allorion   918B 27 Aug 08:04 ..
-rwxrwxr-x   1 administ  allorion    15K 22 Sep  2004 .DS_Store
drwxrwxr-x   4 administ  allorion   136B 21 Aug 06:24 G-Fin
drwxrwxr-x  17 administ  allorion   578B 29 Aug 06:32 Jen

The three directories at the top are displaying this odd behavior. From my own research it appears that the “invisibility bit” is set on these directories.

I run a small lab of Mac’s (all running MacOSX) so my users are constantly doing odd things to their shared files. My users aren’t particularly adept with computers, but somehow they’ve been able to set the “invisibility bit” on these files and others.

I’d like to know how I could restrict their permissions so that the process of making files and folders invisible is at best impossible and at worst very hard.
