How to do a cron job every 72 minutes

Question

How would I get a cron job to run every 72 minutes? Or some not so pretty number like that?

Answer 1

Use at (man at). Have your app or startup script calculate a startup time 72 minutes in the future and schedule itself to run again before it starts working.

Available on windows xp and vista too.

Here's an example for gnu/linux: at -f command.sh now + 72 minutes
