Crontab first value

Hi

On crontab i know that the first value (*) is minutes and it can be set from 0-59

But i don't know what it does if used as:

1) */1
2) /1

---

Can you please let me know what it will do in case 1 and what in case 2 ?

Thank you !

 

Thanks for the link RoldanLT

But i just want to know for those two scenarios only

 

Thanks George so if i add in the first value in minutes this:

*/1

It will run every minute or every fist minute of the hour?

 

yes ok both are the same but does this run every minute?

 

Ok got it thanks
