What's the difference between 30 * * * * python ~/scripts/temp.py
and */30 * * * * python ~/scripts/temp.py
?
My crontabs always had */30
to define "every 30th..."

30
means "at minute 30", so it only runs once every hour, while */30
means "on every 30 minutes", running twice every hour, at minutes 0 and 30.
Thank you very much.
Worked like a charm !
