(in a non-sadistic manner) ;-)
Kill 'em all! (at the end of the day) ;-)
Here's how I do it. I have a script called "stop" located in /usr/bin.
It's designed originally to "kill" a single user, but I have taken that
script and made another script that can be launched as a cron job to
"purge" the server. First the "stop" script....
#!/bin/sh
# usage stop username
# stop
# script to logoff a student
#
if [ $1 != "root" ]
then
for i in $(pgrep -u $1)
do
kill -9 $i
done
else
clear
echo "Can't kill the root!!"
fi
Now the script to "stop" them all:
#!/bin/bash
for x in `ls /home`; do
echo "Killing $x ..."
stop ${x}
done
I called this one "stop-all", made it executable (chmod a+x stop-all) and
put it into a cron job. Works pretty slick! :-) YMMV
PS....doesn't matter if /home is local or mounted via NFS (like
Samba/LDAP) it simply reads the directory listing of /home to get
usernames. If your home dirs are in a different location or separated by
YOG or something like that....just add the extra step to call that
directory. Something like:
for x in `ls /home/2007`; do
