How To Create a Sudo User on Ubuntu

sudo is a Linux command which provides a mechanism for allowing administrator privileges to a normal user. In this tutorial, you are going to learn how to create sudo user on Ubuntu.
In this guide, we will show you how to create a new user on an Ubuntu machine and give it sudo access. You can then use this user account to execute administrative commands without a need to logging in to your Ubuntu server as a root user.

Creating a New Sudo User in Ubuntu

Follow the steps below to create a new user account and give it sudo access. If you want to configure sudo for an existing user, skip to step 3.

1. Log in to your server

Log in to your system as the root user:

ssh root@server_ip_address

2. Create a new user account

Create a new user account using the adduser command

adduser rasho

You will be prompted to set and confirm the new user password. Make sure that the password for the new account is as strong as possible.
Example output:

Adding user `rasho' ...
Adding new group `rasho' (1001) ...
Adding new user `rasho' (1001) with group `rasho' ...
Creating home directory `/home/username' ...
Copying files from `/etc/skel' ...
New password:
Retype new password:
passwd: password updated successfully

Once you set the password the command will create a home directory for the user, copy several configuration files in the home directory and prompts you to set the new user’s information. If you want to leave all of this information blank just press ENTER to accept the defaults.

Changing the user information for rasho
Enter the new value, or press ENTER for the default
    Full Name []:
    Room Number []:
    Work Phone []:
    Home Phone []:
    Other []:
Is the information correct? [Y/n]

3. Add the new user to the sudo group

By default on Ubuntu systems, members of the group sudo are granted with sudo access. To add the user you created to the sudo group use the usermod command:

usermod -aG sudo rasho

Test the sudo access

Now, test sudo access on a new user account by switching to rasho’s account.

su - rasho

Use the sudo command to run the whoami command:

sudo whoami

If you have sudo access then you will get below output:


How to use sudo

To use sudo, simply prefix the command with sudo and space:

sudo ls -la /root

Now enter the password of the new user to get the list of files:

[sudo] password for username:
