You should specify the shell on the 1st line of the script.

Also it's not wise to put scripts directly into /etc/rc3.d
you are better off putting a chkconfig compatable script into /etc/rc.d/init.d and using chkconfig to create the required sym links

Try this scrip, save it as /etc/rc.d/init.d/stnotify

Code:

#!/bin/sh
#
# stnotify        Notify sysadmin system startup
#
# chkconfig: 2345 87 03
# description: Send SMS to sysadmin when system starts.
#
 
. /opt/scripts/function.sh
PATH=/usr/bin                            
EMAIL_ADD=<email address>      
 
#-------------------------------------------------------------------------------
 
case "$1" in
    start)
        echo "$WT_SYSTEM is rebooted" | mailx -s "SYSTEM is rebooted" $EMAIL_ADD
        Func_SMS " SYSTEM is rebooted"
     ;;
     stop) ;;
     *) echo "Usage: $0 {start|stop}"
        exit 1
esac

Then use chkconfig --add stnotify to install your script (it will create symbolic links for the start and stop version of the script at the required run levels).

Note the same script could be enhanced to notify you if the system is restarted, shutdown or put into single user mode.

SERVICE(8)						      System Manager's Manual							SERVICE(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service	runs  a System V init script or systemd unit in as predictable an environment as possible, removing most environment variables and
       with the current working directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT, or the name of a systemd unit.  The  existence  of  a
       systemd unit of the same name as a script in /etc/init.d will cause the unit to take precedence over the init.d script.	The supported val-
       ues of COMMAND depend on the invoked script. service passes COMMAND  and OPTIONS to the init script unmodified. For systemd  units,  start,
       stop, status, and reload are passed through to their systemctl/initctl equivalents.

       All scripts should support at least the start and stop commands.  As a special case, if COMMAND is --full-restart, the script is run twice,
       first with the stop command, then with the start command.

       service --status-all runs all init scripts, in alphabetical order, with the status command. The status is [ + ] for running services, [ - ]
       for stopped services and [ ? ] for services without a status command.  This option only calls status for sysvinit jobs.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

       /{lib,run,etc}/systemd/system
	      The directories containing systemd units.

ENVIRONMENT

       LANG,  LANGUAGE,  LC_CTYPE, LC_NUMERIC, LC_TIME, LC_COLLATE, LC_MONETARY, LC_MESSAGES, LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEA-
       SUREMENT, LC_IDENTIFICATION, LC_ALL, TERM, PATH
	      The only environment variables passed to the init scripts.
