linux - Screenshot cron job not working

linux cron screenshot

Vilhelm Frändberg

I've been searching all over the internet for an aswer to this but can't seem to find anything that works for me.

I want to run a cron job that automaticly takes a screenshot every minute. The script look like this:

#!/bin/bash
cd /home/ville/Skrivbord/screenshot
import -display :0 -win root screenshot.jpg

The code works fine when manually executed but does not work when i run it as a cron job.

The cron file look like this:

* * * * * /root/bin/screen.bash &> /dev/null
* * * * * /root/bin/syncdata.bash

The other task, syncdata works fine.

Here are some of the things i've tried without success:

Change permissions on /root/bin/screen.bash and /home/ville/Skrivbord/screenshot to 777 and change owner to root.

Change filename to screen.sh (maybe there's no difference between .bash and .sh?)

Change the import line to "import -win root screenshot.jpg" and "import -display :0.0 -win root screenshot.jpg".

Added the code:

# Set display to :0 if it's not already set.
: ${DISPLAY:=:0}
export DISPLAY

One time above the existing code in screen.bash and one time below.

Changed the line in cron to "* * * * * export DISPLAY=:0 && /root/bin/screen.bash".

Nothing works!

Please help me
