cron

* */1 * * * sh foo.sh

I found this setting on one production machine. And foo.sh was executed every one minute.

I am guessing that the original author of this setting wants it to be executed every one hour.

And I cannot find the official meaning of this setting in the crontab man page. Hence please help.

UPDATE:

I extracted these logs from that machine, however I cannot find the law out of them.
