I'm trying without success to execute a Python script using cron on a Debian Jessie Raspberry Pi.

I can execute the script manually, but it fails to execute with cron.

Here's what crontab -l shows:

*/2 * * * *  /usr/bin/python2 home/pi/Documents/get_temperature.py

I guess there's something wrong with paths in the cron context but I cannot manage to find what.

The path to the get_temperature.py file you have given seems like an absolute path but has not started with a / (/home).

Unless you have home/pi/Documents/get_temperature.py in the home directory of the crontab owner, you need to correct the path:

*/2 * * * *  /usr/bin/python2 /home/pi/Documents/get_temperature.py
  • Thanks , it's working now. I have to buy some glasses I guess. 2 hours on that for a single / ! :-) – SadE Nov 26 '15 at 21:17
