How to set up a cron job to run an executable every hour?

If you're using Ubuntu, you can put a shell script in one of these directories: /etc/cron.daily, /etc/cron.hourly, /etc/cron.monthly or /etc/cron.weekly.

0 * * * * cd folder_containing_exe && ./exe_name

should work unless there is something else that needs to be setup for the program to run.

You can also use @hourly instant of 0 * * * *

The solution to solve this is to find out why you're getting the segmentation fault, and fix that.
