I need help with creating a simple bash script

Issues & Assistance Unsupported Software (AUR & Other)
1

My goal is to create a script, when executed creates 2 files, a systemd service and another script, and that service should execute that script on startup. Here is the script:

#!/bin/bash
touch  /etc/systemd/system/youtube.service
echo ' [Unit]
After=network.target
Description=youtube.

[Service]
Type=simple
ExecStart=/bin/bash /home/youtube.sh
Restart=on-failure
RestartSec=10

[Install]
WantedBy=multi-user.target ' > /etc/systemd/system/youtube.service

chmod 644 /etc/systemd/system/youtube.service
systemctl enable youtube.service
systemctl start youtube.service
touch /home/youtube.sh
chmod +x /home/youtube.sh
echo ' #!/bin/bash
xdg-open youtube.com ' > /home/youtube.sh

The problem i have that on startup nothing happens. Both files are correctly created, and when i execute the youtube script, youtube opens.
so there should be something wrong with the service file.

You may need to call systemctl daemon-reload after you change the files on disk.

More importantly, what you are trying to won't work.

What is the actual goal here?

Like i said above, my goal is to create a bash script that creates 2 Files, one systemd service and another bash script. And that systemd service has to execute the bash script that was created on PC startup.

That isn’t what you are trying to accomplish. That is the implementation you have chosen.

Why are you doing that? What do you want to happen?

What you are doing is trying to run xdg-open as root before you even have a graphical environment available.

so what you are saying im missing some sort of sleep variable, so that the xdg open only happens after the enviroment is active. Thanks
I will try that

No, I am saying your plan, whatever it is, is completely and fundamentally flawed.

Normally, I would help you, but since you refuse to answer my question, I guess I can’t.

I answered it 2 times. I guess i dont know what you mean with your question then. I said what i want to happen, and you ask me what i want to happen..

Writing a script that creates a service isn’t what you want to happen.

You are writing that script for a reason, correct? You are trying to open youtube in some circumstance.

What is the reason, what is the result you want?

I want a script that i can give to someone, like a friend that he only has to execute and then everytime the PC is restarted an action, in this case youtube opens, happens.

11

Just put the script in the autostart.

That way it will run as the user after the DE is available.

You don't need a systemd service for that.

So, it's possible that there's some way to do this with the implementation you've chosen. I do not think a sleep variable alone is going to do what you want, though.

If all you're trying to achieve is starting YouTube after you log in, there are much better ways to do this. What I would recommend is putting a modified yourbrowser.desktop file, or even just a custom youtube.desktop file in ~/.config/autostart/. This will work on any DE/WM that implements XDG Autostart which should be the case if xdg-open is working.

Okey, i will try that. But i hate this trend that the help is to show an other way, even if it is easier than what i wanted... I want my thing to work cause i think it should work like this too but then someone wants to force an other way on me.

If you cannot solve the problem, then detach yourself from the problem.

This is because you’re creating a system service that runs an action that requires an active user session - it won’t work.

To echo SonarMonkey, if you want to run something on login for all users then put a .desktop file into /etc/xdg/autostart/; for a single user then into ~/.config/autostart/ .
