crontab scheduling

[Alextroy]

Hi,

I need to program a cron task, but I need that it execute in some concrete hours...

8:00
9:00
10:30
11:00
12:00
13:30
15:00
16:00
16:30

I think that I´ve a solution spliting it in two commands:

00 8,9,11,12,15,16 * * * sh.....
30 10,13,16 * * * sh...

but my question is... if is possible program it on a single line?

regards
