How to Run Scripts on Start up in Ubuntu

There are two ways to run scripts on start up in Ubuntu – using rc.local file and using crontab.

$ sudo vi /etc/rc.local

Let us say you want to run a script at /home/ubuntu/ on startup. Then add the following line to rc.local file.

$ sudo /home/ubuntu/ &

Please note, you need to provide the full path of the command or script that you want to run on startup. Save and exit the file.
