How to run an application using sudo without a password?

I've made a script that preforms various system tasks, that I run regularly, but I have to use sudo to run the script, despite the fact that I own it because it runs root privileged commands. How can I add make sudo let me run this one file without having to enter my password every time I run it?

I know that there are questions regarding running commands without a password, but I wasn't able to find one on running a file without a password.

I am aware of the security risks, but I'm at home on a computer that I trust.

I added john ALL = NOPASSWD: /home/john/.script/hibernate.sh to my /etc/sudoers but when running the command sudo sh /home/john/.script/hibernate.sh it still prompts me for my password...

Use visudo for a safe editing environment to edit the sudoers file. This script is a wrapper around vi that also does syntax checking when you save the file and won't let you overwrite a valid sudoers file with an invalid one.

Add a line like this:

username ALL= NOPASSWD: /path/to/your/script

The "ALL=" bears some elaboration, it specifies that the permission is granted when the user in question is logged in from any location, locally (console or terminal) or remotely (ssh, etc).
