script running with cron

hobbit666

having a few issues getting a script to run via cron on Ubuntu Mate on a Rasbpi

The RasbPi runs with a user not root - Display1

the script :-

#!/bin/bash
export PATH=/usr/local/sbin:/sbin:/bin:/usr/sbin:/usr/bin

mkdir /tmp/cron.d
sleep 2
echo "Testing Cron: $(date)" >> /tmp/reboot.log
sleep 2
notify-send Testing
sleep 4
chromium-browser http://bbc.co.uk/news
sleep 3
mkdir /tmp/cron2.d

So this is just a test script. So when it runs I can see the folders being created and the .log file either gets created to appended to with the "testing cron <date>"

But I don't see the notify-send or chromium.

The reboot.sh file is located in /etc/ folder.
If I run the file within /etc/ with ./reboot.sh it runs

permissions on the file at the moment are
-rwxr-xr--x 1 root root reboot.sh

Guessing as its not running the commands it will be something simple, but I have no idea

Add full path to notify-send and chromium-browser binaries and test again. Also your PATH variable is missing / after =

When I do a whereis notify-send I get:-

/usr/bin/notify-send

so just add that to the line?

/usr/bin/notify-send Testing

@hobbit666 yes.

Still no go.
It's Friday 16:50 and i'm off home in 10 minutes so a job for Monday

Still having Cron job issues.

So ignore the script at the top. I've gone to basics:-

This is the script located here /home/display1/chrome.sh
(this has been created with nano chrome.sh NOT sudo)

#!/bin/bash
sleep 5
pkill -o chromium
sleep 10
chromium-browser https://www.bbc.co.uk &
sleep 5
xdotool key F11

ran chmod +x chrome.sh to add execute

if I ./chrome.sh it runs and chrome opens.

Now if I run crontab -e again no sudo (not sure if I should or not as the script will run with the user logged in


15 15 * * * /home/display1/chrome.sh

when that time comes nothing happens.

Add the full path for every command in the script. Use which $command to find any you don't know (I don't remember offhand where all these things live.)

So I've added the following to the cron job

07 16 * * * /home/display1/chrome.sh > /home/display1/chrome.log 2>&1

Also changed the chrome.sh to just 3 lines

#!/bin/bash
sleep 10
/usr/bin/chromium-browser
sleep 5

So when it runs I look at the log file and see this:-
(Chromium-browser:3494): Gtk-WARNING **: 16:07:12.000: cannot open display:

Ah, there we go. The shell it's running as doesn't have a graphical environment setup. I forget offhand how I got around this because I so rarely have to. The only recent cases I've used fed to feed images to a screen.

@travisdh1 Yeah think I may have found the solutions.
Will test and post back

hobbit666

Looks like I needed to put

export DISPLAY=":0"

originally when I was trying it I didn't have the "

Now to test the whole script
