Ubuntu 18.04 : how to run start up script

  1. Create a service: 
    sudo vi /etc/systemd/system/rc-local.service
  2. Add your code there: 
    [Unit]
Description=/etc/rc.local Compatibility
ConditionPathExists=/etc/rc.local

[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99

[Install]
WantedBy=multi-user.target
  3. Create and make sure /etc/rc.local is executable and add this code inside it:

    sudo chmod +x /etc/rc.local

    #!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

exit 0
  4. Enable the service: 
    sudo systemctl enable rc-local
  5. Start service and check status: 
    sudo systemctl start rc-local.service
sudo systemctl status rc-local.service
  6. If all goes well you can add your code to the /etc/rc.local file then restart it.
