I am not sure how to run a cron job at 3 specific hours every day. I want to run it at 1pm, 2 pm and 3pm.
Is it possible, using a single expression?
you may use this:
# m h dom mon dow command 0 13,14,15 * * * /home/user/command
your /home/user/command will be run at 13:00, 14:00 and 15:00
/home/user/command
