I have an .sh file located at '/home/pi/startup.sh' which I want to have running soon after bootup. I have my crontab with the following information.

# m h dom mon dow user        command
17 *        * * *        root    cd / && run-parts --report /etc/cron.hourly
25 6        * * *        root        test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6        * * 7        root        test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6        1 * *        root        test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
0  0        * * *   root        reboot        
@reboot ( /bin/sleep 30; /home/pi/startup.sh > /home/pi/cronjoblog 2>&1)
#

And the .sh is

sudo mount -t cifs -o guest //◘◘◘.◘◘◘.◘◘◘.◘/Public /home/pi/wdmycloud
#
sudo mount -t cifs -o guest //◘◘◘.◘◘◘.◘◘◘.◘/Jared /home/pi/Jared
#
sleep 10
feh -Y -x -q -D 5 -B black -F -Z -z -r /home/pi/wdmycloud/SkyNetPhotos/

What am I doing wrong? The script, should start a picture slide show using picture from the drives. But nothing happened, even hours of letting it sit.

    What am I doing wrong? Nobody knows because you're not telling us what the problem is. What does not work as expected?

  • The script isn't running when system reboots.

  • How do you know the script isn't running?

  • The script shown is to mount 2 disks from a wireless server that's on the network, and start a slideshow from a folder found on one of the drives.

  • How do you know the script is not running? You need to edit your question and include all relevant detail.

You should consider putting your mount actions in /etc/fstab instead of an @reboot facility in your crontab.

Beyond that, some potential issues:

  1. Your mount commands look suspect. Try something like: 
sudo mount //192.168.1.246/whatever /home/pi/somedir -o username=yours,rw,vers=1.0

Refer to man mount for details on the options. And note in particular: 

Mount options for cifs
       See the options section of the mount.cifs(8) man page (cifs-utils package must be installed).

  1. You've cleverly added the stderr redirect, but you haven't shared with us what you found when you looked in your /home/pi/cronjoblog file... do you mind doing that?

  2. I'm guessing here, but your shell script may need either a shebang as the first line, or change your crontab line to make it clear you want it to run under the bash shell: 

@reboot ( /bin/sleep 30; /bin/bash /home/pi/startup.sh > /home/pi/cronjoblog 2>&1)
  1. And if none of that works, try using complete path specs in your .sh script; for example:

instead of: sudo mount ... , use /usr/bin/sudo /bin/mount ...

etc.

  • 1. I've added the line suggested to the fstab and yet nothing happened

  • 2. I've been trying to get this process to spit out a log to the conjoblog, but it still remains empty.

  • 2. I don't know what you mean by "shebang" I added it to the begging before "sudo mount" and it just tells me "shebang:not found. Mount error (16).

  • @user46629: Please use a search engine. If you Google shebang, you'll get answers like this one

  • I feel really stupid now. And also mind blown about the concept of a shebang.

I would suggest you run your .sh script manually before putting it through the cronjob. You should also check the permissions for the file. I would just allow all users to execute the file :

sudo chmod a+x /home/pi/startup.sh

For the crontab file i think you can do it in this way : 

@reboot sleep 10 && /home/pi/startup.sh

  • Script runs perfectly after system has booted up and I execute it via terminal

  • Good. Is the permission correctly set ? Try running the cronjob the way I posted.

  • I did the "sudo chmod a+x /home/pi/startup.sh" and nothing happened. I applied the changes to the crontab that you suggested and after 2mins of waiting, nothing.
