run cron every minute during a specific hour?

Question

Running a cron job every minute is easy, running it at specific minutes past the hour is easy.

But is it possible to say "only between 1300 and 1400 run every 1 minute"?

	That will (or would, since it has now been edited) run every minute between 1pm and 3pm – David Dorward Sep 25 '11 at 7:07
	I know - Too quick on the post button. Corrected it though. – Ed Heal Sep 25 '11 at 7:08

Just use a * for the minute specifier.

*      13       *       *       *      foo.sh

	Quentin, you say @Ed Heal's answer will run every minute 1pm - 3pm, but your answer is the same. Am I missing something? – Steve Sep 25 '11 at 7:10
	@Steve — That it has been edited since my comment (and within the "no history" grace period). – David Dorward Sep 25 '11 at 7:11
	;o) no problems – Steve Sep 25 '11 at 7:13
