  1. I've written a silly little script that starts an xterm session. I'd like this script to be run as soon as I log in. Where do I add the script to make this possible?
  2. I'm trying to incorporate a status check on any/all NFS mounts on my system into a script. Is there a simple command that does this? I tried Google-ing up an answer but found nothing helpful. I suck. Anyone have any ideas?
  3. What's the best way to disable terminal and modem logins in an emergency panic situation? I know you can set the file /etc/securetty to contain only the local console device, or just comment the rest of the contents, but what are the other options?
  4. .. much appreciated. These commands can be really intimidating for noobs.
  5. Hi all. I'm doing a Crontab assignment and I can't make out what the syntax for one of the questions is implying. Here it is: 1 2 * * * [ -x /usr/sbin/rtc ] && /usr/sbin/rtc -c > /dev/null 2>&1 From my textbook, I can make out the first 5 fields, but I have no idea what that command means. Does anyone know what that madness means?
  6. Great, thanks for the replies. I'll look into some of those suggestions a little further on my own. Thanks again!
  7. Hi all. I'm looking for some help with a homework question that I was unable to complete. Question: A user calls and says all of his windows are hung. He can't do anything. Describe what steps you'd take. My answer was to ssh into the box and start killing processes. However, I only received 1/3 for my answer. My instructor's reply was: this is OK as far as it goes, but what about the mid-range / mainframe scenario (multiple users on the same box) ? Does anyone know what the appropriate approach is here?
