Slackware(64) 15.0 - /etc/rc.d/rc.local is not working

Hi there, for unknow reasons this is not working during boot. the current content /etc/rc.d/rc.local file are the follow :

Code:#!/bin/bash
#
# /etc/rc.d/rc.local: Local system initialization script.
#
# Put any local startup commands in here. Also, if you have
# anything that needs to be run at shutdown time you can
# make an /etc/rc.d/rc.local_shutdown script and put those
# commands in there.

echo 'Ejecutando : /etc/rc.d/rc.local'

# Sincronizar Hora al Iniciar el Sistema :
echo 'Sincronizar Hora'
ntpdate=$(whereis -B "/usr/sbin" "/usr/local/sbin" "/sbin" "/usr/bin" "/usr/local/bin" "/bin" -b ntpdate | grep -i "ntpdate" | cut -d " " -f02 | cut -c11-20)
service=$(whereis -B "/usr/sbin" "/usr/local/sbin" "/sbin" "/usr/bin" "/usr/local/bin" "/bin" -b service | grep -i "service" | cut -d " " -f02 | cut -c11-20)
rcntpd="/etc/rc.d/rc.ntpd"

if [ -z "$ntpdate" ]; then
echo
echo "ntpdate no esta instalado en tu sistema operativo GNU"
echo "Por favor, primero instale : ntpdate"
echo
exit 0
fi

if [ -d "/etc/rc.d" ];then
if [ -f "$rcntpd" ]; then
chmod +x "$rcntpd"

if [ -x /etc/rc.d/rc.qemu-ga ]; then
# Start QEMU Guest Agent:
echo "Starting QEMU Guest Agent: /etc/rc.d/rc.qemu-ga start"
/etc/rc.d/rc.qemu-ga start
fiAfter i write all things i want inside that file i use the follow commands :

su -c "chmod 755 /etc/rc.d/rc.local ; chmod +x /etc/rc.d/rc.local" root
- Ask for the password, i put and press enter
- i restart the system, and is not working.

The current Desktop Env i am using is : KDE Plasma.

What i am doing wrong ?
