1. We run this script from cron every ten minutes, killing off idle sessions that are older than 30 minutes.
   Note the list of exempt users. We wouldn’t want to kill the CEO’s session.

   #########################
   #! /usr/bin/awk -f
   
   BEGIN {
   system("who -u | sort +5 > /tmp/loginfile");
   system("echo User Sessions Killed > /tmp/killedlogins");
   system("echo `date` >> /tmp/killedlogins");
   while (getline = 1) || (timearray[2] >= 30)) &&
   # list of exempt users below
   ($1 != "root") &&
   ($1 != "legacy") &&
   #($1 != "ceo") &&
   #($1 != "cio") &&
   #
    { {
   system("ps -ef | grep " $1 " | awk '{print $2}' | xargs kill -KILL");
   print $1, "[Idle " $6 "] Session terminated from " $8 >> "/tmp/killedlogins";
   };
   };
   }
   system("rm /tmp/loginfile");
   system("chmod 644 /tmp/killedlogins");
   }
   

2. Note that the tcsh example should be

   set autologout=5

   for consistency – here the time is expressed in minutes, not seconds.

3. Hi,

   Is there any way to do this for plain Bourne-Style-Shell (sh).

   Thanks.

4. echo “to logout all ideal user ” | sed ‘s/ideal/idle/g’
