Following a range with ‘‘/<number>’’ specifies skips of the number’s value through the range. For example, ‘‘0-23/2’’ can be used in the hours field | to specify command execution every other hour (the alternative in the V7 standard is ‘‘0,2,4,6,8,10,12,14,16,18,20,22’’). Steps are also permitted after an asterisk, so if you want to say ‘‘every two | hours’’, just use ‘‘*/2’’. I would expect that to yield a run every 12 hours by your explanation, 24hr divided by 2 No, I don't know what is correct (I suspect it is every 2 hours) But I haven't used that in a while. Would need to test.
