Ubuntu how to config sh file bootstart ?

1. Open /etc/rc.local file with this command:

vim /etc/rc.local

1. Add your script that you want to run on boot process there, for example:

sh /home/ivan/iptables.sh echo 'Iptable Configured!'

1. Review the comments included in that file and make sure a exit 0 is at the end.
2. Save the files. And your script will run on boot process.
