How do I make a script run upon startup of the Ubuntu machine?

Question

I want to run /home/myuser/go.py

How do I make that run in the background, everytime my linux machine boots up?

Answer 1

Simple way

You can add this script into /etc/rc.local file (before exit line), e.g.

/home/myuser/go.py &

Where & at the end will run the script in the background.

Make sure that you've execution flags. To test it, simple run from the terminal:

sh /etc/rc.local

Answer 2

You can put a script in the /etc/init.d/ directory (eg: /etc/init.d/go.py) for anything you want to run at bootup time.

Answer 3

There are many ways to do this (depending on which distribution of linux you are using there are different tools that are offered).

The easiest way is simply adding the script to /etc/init.d and then running the command

chmod +x go.py
update-rc.d go.py defaults

If you already set up the service, you may also do so via the chkconfig command (that is if the command is available).

In that case, this command should work:

chkconfig --level 35 go.py on

cron has a special @reboot option that allows for this. Nice and simple.

A normal cron task might be:

* * * * * /path/to/app

A @reboot cron task might be:

@reboot /path/to/app
