Unix Tip #4513- July 20, 2025
DID IT REBOOT?
If you believe your users
like to reboot their systems,
here is a way you will be
able to detect it.
#!/bin/ksh
#
# Boot Notification Script
# /etc/rc2.d/S99notify - Sends e-mail notification to the
administrators
# when the system is booted.
#
#*****************************************************************
PATH=/usr/sbin:/usr/bin
DATE="`date`"
SRVNM=`uname -n`
# The next variable can be set for multiple addresses
# (i.e. jsmith@yahoo.com,jsmith@hotmail.com)
MAILADD=monitor
mail $MAILADD <
From: $0
To: $MAILADD
Subject: Boot of $SRVNM
