Where can I set environment variables that crontab will use?

Question

I have a crontab running every hour. The user running it has environment variabless in the .bash_profile that work when the user runs the job from the terminal,

Answer 1

Unfortunately, crontabs have a very limited environment variables scope, thus you need to export them every time the corntab runs.

An easy approach would be the following example, suppose you've your env vars in a file called env, then:

* * * * * . ./env && /path/to_your/command

this part . ./env will export them and then they're used within the same scope of your command
