No /etc/rc.local file on Ubuntu 18.04? Here's what to do...
The /etc/rc.local file on Ubuntu and Debian systems are are used to execute commands at system startup. But there's no such file in Ubuntu 18.04.
So what can we do? We can just create the file. Let's do it. Create /etc/rc.local file with nano text editor,
Paste the following lot,
# 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
# By default this script does nothing.
That's the content of Ubuntu 16.04's stock /etc/rc.local file. Now make it executable,
chmod +x /etc/rc.local
That's it. You can now use this file to execute commands at system boot. Just paste your commands above the line that says exit 0
