How to execute a job in cron using sudo?

Question

ubuntu

I do a cron task on my username
crontab -e
0 */3 * * * /home/gray/bbnvp.sh
to execute a file every 3 hours. But inside the commands that need to be executed using sudo , how is it to get everything right?

Answer 1

Give the user the ability to execute these commands with sudo without a password, or immediately run as root.

Answer 2

run visudo
and there at the end:
gray ALL=(ALL) NOPASSWD: bbnvp.sh
