Nice! Just as an aside: if you're going to run this sort of script during the boot sequence, do yourself a favor and use the -n option on those ls(1) commands. That will keep it from calling getpwent()/getgrent() to map the UIDs/GIDs to names. Why bother? Well, if your system is configured to use LDAP as its password database and the network ain't up yet, it's kind of not a good idea to map those IDs to names. Can you say "60 second timeout"? :-) And yes, I did find out the hard way when I had a guest that took forever to boot. One really should be using readlink(1) instead of ls for this sort of thing, but unfortunately the powers that be placed readlink in /usr/bin, which is often not available at boot-time. So we're stuck with ls. - MacK. ----- Edmund R.
