[How can i run a bash script on boot with Pi 4B /4GB]

[Cubuss]

i need to run a simple .sh script on boot that requires internet,
But it doesnt start when i reboot or boot the pi, i already tried using crontab

Code: Select all

@reboot script.sh

also tried messing around with rc.local with no luck,

Any suggestion or help is appriciated

My scripts wait until there is a valid IP address.
Then they send me an email so I know what it is.
It can take some time before the server on a network assigns it.
30 secs after booting is not unusual.

You shouldn't assume that cron knows where to find your script. It's best to use the full pathname.
If you redirect the script output to a logfile you may get a clue to what went wrong.

Try @reboot /home/pi/script.sh >/home/pi/script.log 2>&1 (or wherever script.sh is).

You could put sleep 10 in the script to see if that gives time for a connection

You could write systemd service to execute it for you once the network is up rather than a sleep line... I assume your distro is using systemd.

For an example, see: https://github.com/graysky2/odroid-auto ... ge.service
