crontab/bash issues (Pixel OS)

[FoxJr]

Dear all,

I'm an owner of a Raspberry Pi 3 unit which I'm currently testing for digital signage use. The problem i'm having is with bash commands calling chromium-browser.

startup script
Location: /home/pi/Scripts/startup.sh

Cron -l (in sudo mode)
30 9 * * * /home/pi/Scripts/startup.sh

-----------------------------------------------------------
!#/bin/bash

#Reset OS
#/sbin/shutdown -r now

#Launch Chromium
/usr/bin/chromium-browser

#End
-----------------------------------------------------------

File permissions are set all to anyone

If i run this script from terminal it works fine, however if i can this via crontab at the specified time it never executes, therefore chromium never starts. However if i comment the command to launch chromium and instead remove the comment from the restart OS command it works fine. So i believe that i'm doing something wrong when it comes to launching the application.

Can anyone highlight the issue? as i'm really puzzled.

Hope I provided you with all information needed, thanks in advance for your help!

Why are you wanting to open a browser owned by root? Wouldn't this be better in the user's (pi's) crontab?

Anyway it probably isn't working as root doesn't have the authority to open a window on another user's desktop.

I assume the mistake in the shebang is a typo when copying it to here (you have !# rather than #!).

you really dont want to use cron to run stuff on a desktop and you really really dont want to run a root browser on a desktop
use the lxde startup stuff for this

Chromium will refuse to run as root. You could make a script and add it to the lxde startup script to wait until the right time comes and then start Chromium

Thanks for your prompt reply guys, will check this lxde startup procedure and revert back.

Actually, you don't revert at all. You "report back".

Tried with lxde startup, no success.

Here is what i did:
sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

added the following at the end of the file;
@chromium-browser (1st attempt)
@/usr/bin/chromium-browser (2nd attempt)

Any ideas?

Guys just a few lines to inform you that issue has been fixed.

Here is how:

sudo nano ~/.config/lxsession/LXDE-pi/autostart
@chromium-broswer (or any other application you want to run)

sudo???

[DougieLawson]

sudo nano ~/.config/lxsession/LXDE-pi/autostart

Stop prefixing every command with sudo, you'll break your system or compromise security if you persist in that pernicious practice.
