I decided to make autorun through cron. In the terminal after writing crontab -e opens the editor in which i write

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=roma
HOME=/
*/1 * * * * root run-parts  /home/roma/autorun.sh

In the inside to autorun.sh it is written:

#!/bin/sh
cd image
mirage 8475.jpg

This script opens the image in the directory image

Then I save the file. I'm waiting about 1 minute, but nothing happens. What is the problem?

Have you made the script executable? chmod +x /home/roma/autorun.sh – konstructor Mar 08 '18 at 12:23
chmod +x /home/roma/autorun.sh - did not help me. – kek121 Mar 08 '18 at 12:26
Where does the image folder reside? If you run 'mirage /full/path/to/image/8475.jpg' does the command work? – konstructor Mar 08 '18 at 12:34

What is mirage? Programs started from cron are **not** connected to a terminal, so any interactive program should fail for either no DISPLAY if graphic of EOF on stdin if command line – Serge Ballesta Mar 08 '18 at 12:35
mirage /full/path/to/image/8475.jpg - working. – kek121 Mar 08 '18 at 12:51
Then you should look at the comment by @SergeBallesta – konstructor Mar 08 '18 at 12:58
I chack cat /var/log/syslog. I found line " Mar 8 14:52:01 roma CRON[7165]: (roma) CMD (/home/roma/autorun.sh)" – kek121 Mar 08 '18 at 13:02
Mirage is an image viewer. – kek121 Mar 08 '18 at 13:04
What is it you are trying to accomplish by triggering an image viewer once every minute? If you are trying to set an rotating desktop background or something similar, there are other ways to do that. A quick google search might be of help. – konstructor Mar 08 '18 at 13:34
