Question

I need a cron statement to run for few hours eg 1-8 then 10-15.
In this case will the following statement work,

0 1-8,10-15 * * * 

If not can anyone help me?

Thanks in advance,
Gnik

Answer 1

You cannot, you can use either multiple values OR a range

0 1,2,3,4,5,6,7,8,10,11,12,13,14,15 * * *

Source:

Time tags are separated by spaces. Do not use spaces within a tag,
this will confuse cron. All five tags must be present. They are a
logical AND of each other. There is another space between the last
time tag and the first command.

A time tag can be a wildcard “*”, which means “all”. It can be one
value, several values, a range, or a fractional range.
