PC speaker 'alert'

[Chuck Gelm <nc8q@gelm.net>]

Howdy, Y'all:

 I'm monitoring my /var/log/messages file and I'd
like to have the PC's speaker beep when there is a new
entry.  I am monitoring 'DENY'ed packets.  I am now
using 'cut' and 'grep' and 'tail' to show the last
11 denied packets.  How can I cause the PC speaker to
beep when the last 11 lines are different the the
previous 11 lines.

Here is what I am using now:

#!/bin/sh
#
grep DENY /var/log/messages > t
cut -f2 -d\= t > u
cut -f2 -d" " u > v
cut -f1 -d: v > w
tail -n 11 w > deny.txt
clear
echo ""
cat deny.txt
echo ""
chmod 777 deny.txt   ; v
chgrp users deny.txt ; so that my other workstations can see

Regards, Chuck
