rc.local Ubuntu 18.04

Ubuntu 18.04 does not have a rc.local by default, but does use it if existant.

• vi /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.
    
    # Custom commands
    uptime
    
    exit 0

• chmod 700 /etc/rc.local
