Highly recommended things!

This is my five-star list. These are my favorite things in all the world.

A few of these works have had an extraordinary effect on my life or way of thinking. They get a sixth star. ★

The most likely reason is that cron runs in a very limited environment and doesn't have access to gsutil or to gsutil's configuration.To fix this you should set your Path variable and the gsutil configuration inside your script like so:


#!/bin/bash
PATH=path/to/gsutil
export BOTO_CONFIG="/path/to/.boto"

#rest of script here
