I'm using Ubuntu 11.10 and I've to execute a shell commands at the startup.

java -jar selenium....

I tried with this but nothing:

sudo gedit /etc/init.d/ 
sudo chmod a+x /etc/init.d/
sudo update-rc.d defaults

Do you know how I can do this?

Thank you!! Marco

If programs in your script depend on other resources being up and running, you need to specify priorities in your update-rc.d command. – RedGrittyBrick Apr 18 '12 at 14:20

Ubuntu has abandoned SysV init script approach to booting the system.

You're welcome. – bryan Apr 23 '12 at 14:20
I don't understand a thing: if I execute the shell command at the startup it works but selenium gives me an error, if I execute the same command in the terminal all works.. – Mark Design May 2 '12 at 8:09

You could add a line to your crontab:

@reboot command here

That pretty much guarantees it won't happen more than once (like /etc/rc.local or gnome sessions) It also lets you ensure it is run as the correct user very easily.
