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

Question

I need to set up a cron job that runs an executable compiled using gcc once every hour.

I logged in as root and typed crontab -e

Then I entered the following and saved the file.

0 * * * *  /path_to_executable 

However, the cron job does not work.

I see that when I type /...path_to_executable I get a segmentation fault. I can only execute the executable from the folder it is located in. Is there a way I can solve this problem?

Answer 1

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

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