I write a script and set it as a cron job. But due to a difference of environment variables it doesn't work as it should be.

In that case I change a little bit with crontab -e and set a cron job time closest minute, and wait next minute to come to show the result. I feel this is a totally absurd approach, but I don't know better way to do it.

If there is a way to run a script as if it is called inside cron job, I'm going to use it.

Does anyone know how to do it?
