I wish for the following script to run once when I login or when the computer starts up. The above script is located in /home/karl/.scripts/startup/sensei-raw-startup.sh.

I DO NOT wish to use the GUI to add the script. I wish to learn a bit more about how to do it manually.

What files do I need to create, what must be in them and where should they be located to be able to run my script which is located in the said directory.

Solution

1. Using /etc/profile.d

You can run the script on login by placing the script in /etc/profile.d/

These files are executed upon login.

To create a symbolic link to the file you want to execute, use

sudo ln -s /home/karl/.scripts/startup/sensei-raw-startup.sh /etc/profile.d/myscript.sh

2. Using upstart

Another possibility is to use upstart

start on desktop-session-start

and place your script there.

Here they explain how to run an script at boot as root (in /etc/init) as user (/home/user/.config/upstart) or even with a "@reboot" task in cron: askubuntu.com/questions/814/how-to-run-scripts-on-start-up

[mchid]

Either rclocal or systemd on a newer system as seen in the posted link.

@Julen creating a cronjob is not the right solution, as @reboot starts the script when the system is started, not when the user logs in. help.ubuntu.com/community/CronHowto

How does this handle sudo commands?

[mcantsin]

@KarlMorrison personally I think you should use the upstart solution, as /etc/profile.d is not really meant to be used like this. My suggestion is more a "hack". I you still want to try, just add the echo "password" in front of the | sudo -S part, whereafter sudo won't ask for the password any more.

Indeed I've tried: askubuntu.com/questions/704815/upstart-not-running-sh-script perhaps you could see whats wrong? :/

[mcantsin]

@KarlMorrison I think the error is with the part start on runlevel [2345]. Use the solution I suggest: start on desktop-session-start which I think is what you want: starting when the desktop session starts. - no? (Regarding upstart I will respond in your other ticket)

[Karl Morrison]

Just tried with what you suggested, still no effect :( I need the script to be loaded when the login screen appears (as the mouse can be used there). So basically before logging into the user.
