I am attempting to enable cron to run this python script on reboot.

I have already tried both the GUI and script file version of cron, and neither will run the script, while if I run it in terminal, it works. I have also tried to put it into some start up scripts as well, but had no luck.

(OnReboot.py) Python code, located in the home folder

import subprocess
firefox_path = '/usr/bin/iceweasel'
cmdline = [firefox_path]
with open('url_list.txt', 'r') as url_file:
 for url in url_file:
 cmdline.append(url)
subprocess.Popen(cmdline)

Cron code

@reboot python ./OnReboot.py

I expect that when the Pi restarts, the python code will be ran automatically.

python ubuntu cron raspberry-pi

You're asking about @reboot, but you aren't using it!

If you want your script to run on reboot, specify @reboot instead of a time specification in your crontab, e.g.

@reboot python ./OnReboot.py

Additionally, a relative path like ./OnReboot.py may not work correctly in a cronjob, as cron's working directory may not be what you expect. Use an absolute path (e.g. /path/to/OnReboot.py) for best results.

  Sorry for the confusion, in cron, I have it typed as @reboot and it still does not work, I just mistyped it in the question.
