Question

With cron, if I wanted to run a command every 5 mins it would be:

*/5 * * * * command

But what if I wanted to set a list of minutes specifically?

Like at 5 past, 18 mins past and 15 minutes too the hour? I’m guessing this:

5,18,45 * * * *

Answer 1

Yes, the solution you specified is correct.

0,5,55 * * * * command       # run the command at the top of the hour, at
                             # the 5 minute mark and at the 55 minute mark.
