I am trying to execute one script at startup on ubuntu 16.04 LTS desktop. I have added my script to /etc/init.d
location. But after restart I am unable to see my script running using
pidof -s pgd
Once I execute this command sudo service run_pgd start
it started with a pid. I want this script to be executed in the background.
I have achieved the same thing by adding the script in rc.local
it was working fine. But I am having issue in /etc/init.d
location This is the script file
#!/bin/bash
###
# Configuration section
#
# Specify full path to directory with pgd executable and config files here:
# For example: PGD_DIR="/usr/local/Neurotechnology/Activation"
PGD_DIR="/opt/Neurotec_Biometric_10_0_SDK/Bin/Linux_x86_64/Activation"
#
# End of Configuration section
###
# If PGD_DIR is not set use the directory of current script
if [ ! "${PGD_DIR}" ]
then
PGD_DIR=`dirname "$0"`
# If we were called through relative path, make absolute one
if [ "${PGD_DIR:0:1}" != "/" ]
then
PGD_DIR="$PWD/$PGD_DIR"
fi
fi
NAME=pgd
PROGRAM="${PGD_DIR}/${NAME}"
if [ "`uname -s`" = "Darwin" ]
then
LOG=/Library/Logs/pgd.log

LOG=/tmp/pgd.log

Is there something wrong with my script ? What are the required changes do I need to make to execute this script at startup ? I want this script to be executed even if the system reboots after crash or any failure.
