[SOLVED] Is `*/1 * * * *` and `* * * * *` equivalent in CRON?

Issue

As I have recently seen something like

*/1 * * * * ./script.py

I would like to know if it means the same as

* * * * * ./script.py

Solution

Yes, it does.

*/X means: every X minutes * means: every minute

So all together */1 means exactly the same as *.

From man cron:

Step values can be used in conjunction with ranges. 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''.
