Crontab Not working appropriate?
 
I created two scripts. One for opening an image with kuickshow, the other for powering off computer.


my_picture script contains:
Code:
#!/bin/bash
# Warning to Shutdown

kuickshow '/home/bdd86/Documents/goodnight.gif'
my_poweroff script contains:
Code:
#!/bin/bash
# Poweroff now

poweroff

Crontab -e
Code:
53 22 * * * '/home/bdd86/Documents/my_picture'
54 22 * * * '/home/bdd86/Documents/my_poweroff'
Nothing happens at 10:53.... my_picture does not run... but a minute later my_poweroff runs perfect.

When I run ./my_picture in konsole it opens fine. but Crontab just doesnt seem to run it at all?

How can I get crontab to open a picture in kuickshow?

THank you!

kuickshow is an X application which crontab cannot handle.

Ok, how can I make a script Open up a Konsole, with pre-written text in it, saying You have 30 Minutes until computer power off?

try adding DISPLAY=:0 to the begining of your crontab file...

No this didn't work, heres my crontab file

Code:
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.6299 installed on Fri Jun 16 00:00:21 2006)
# (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)
DISPLAY=:0
01 01  * * * '/home/bdd86/Documents/my_script'
50 23 * * * '/home/bdd86/Documents/my_poweroff'

Try adding the line directly to crontab using "crontab -e". A script is not required in most cases.

DISPLAY=:0
00 21 * * Mon-Fri kuickshow /home/bdd86/Documents/goodnight.gif

This works fine for me... Test it and see...

Have you considered the shutdown command? It can be scheduled and gives a warning to logged in users one minute in advance.
Needs to be run by the root user...
For example:
Code:
sudo shutdown 00:35

or

su - -c "shutdown 00:35"
More options from man shutdown
