Run cron job every 10 minutes, from 4:40 to 0:15

Question

I need to run a cron job every 10 minutes, only between 4:40 and 0:15. I've managed to schedule the cron job to run from 4 to 0 o'clock, but can't figure out how to schedule it further. This is what I came out with: */10 4-23,0 * * * script

Answer 1

Sometimes you just have to break out the ugly, and duplicate entries to get selection logic like that. It should work and be pretty apparent with what it's doing without uber cron-fu knowledge.

40,50 4 * * * script
*/10 5-23 * * * script
0,10 0 * * * script

Oh, and a helpful site for generating these: http://www.openjs.com/scripts/jslibrary/demos/crontab.php
