Is `*/1 * * * *` and `* * * * *` equivalent in CRON?

cron

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''.

Problem

As I have recently seen something like ``` */1 * * * * ./script.py ``` I would like to know if it means the same as ``` * * * * * ./script.py ```
