Sudo means Superuser Do. What is sudo means? In short, it is a utility in Linux operating systems that allows users to execute commands with the privileges of superuser or another user without having to log in as that user. It can be made on VPS and dedicated servers.

Typically, running commands using Sudo requires entering the current user’s password. However, you can configure Sudo to not require a password for certain commands or for a specific user. Here’s how to do it:

Open the Sudo preferences file: First, open the Sudo preferences file in your text editor. This file is usually located in /etc/sudoers or /etc/sudoers.d/. For example, to open a file in the Nano editor, use the following command:

sudo nano /etc/sudoers

Find the Defaults line: In the open file, look for the line starting with Defaults, which may look something like this (also shown in the screenshot)

Defaults env_reset

Add the NOPASSWD option. How to do it? To allow all Sudo commands to run without prompting for a password, add the following line under the Defaults line:

username ALL=(ALL) NOPASSWD:ALL

Replace username with your username. Save changes: After making changes, save the file and close the editor. To save click exit and Y as YES.
