Getting some jobs to run under cron(1) can be confusing and difficult since cron executes tasks in the crontab(5) file with a different underlying environment than a user normally runs in. What works from you login shell command line often won't from a cron job. Here is how to get it back.

What determines cron's environment?

By default, cron runs with the barest environment. You can discover this by running the following in your crontab:

* * * * * (/usr/bin/date ; /usr/bin/env | /usr/bin/sort) >> /tmp/my_cron_env 2>&1

This will run the task every minute, with stdout and stderr sent to the file. You should make sure to remove or comment out this line after a minute or so or you'll build up quite a long file.

WARNING Setter methods don’t return what you might think. When you use the syntactic sugar that lets you make calls to = methods look like assignments, Ruby takes the assignment semantics seriously. Assignments (like x=1) evaluate to whatever’s on their right-hand side. Methods usually return the value of the last expression evaluated during execution. But = method calls behave like assignments: the value of the expression ticket.price = 63.00 is 63.00, even if the ticket= method returns the string “Ha ha!” The idea is to keep the semantics consistent. Under the hood, it’s a method call; but it looks like an assignment and behaves like an assignment with respect to its value as an expression.
