We talk about “sudo” privileges, we are talking about the “sudo” command.

The “sudo” command allows users to run any other commands, services, or program with the privileges of another user, and by default, it took the privileges of the root user.

In this tutorial, we will learn how to create a new user with sudo access on Debian Operating System. So, you can use this user to execute an administrative command in the system without login as root user in your Debian machine.

Create a Sudo User

We will create a new user in Debian machine with sudo privileges in simple three steps. If you want to give sudo privileges to an existing user, you can directly go to step 3.

Step 1: Log in to your server

In the first step, you need to login into your system or server with root user, using the following command:

$ ssh [email protected]_ip_address

Step 2: Create a new user account

Now, we will create a new user in this Debian machine by using ‘adduser” command. Please replace the “user_name” with the user name that you want to create:

$ adduser username

Your screen will be prompted to set the password for your new user. Make sure the password of a new user is to follow the secure password guidelines.

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

Once a password is get configured for a new user, the command will create a home directory for the new user. It will copy several files in the home directory and ask you to set new user’s information. If you want to leave all of these information blanks just press “ENTER” and accept configured default values.

Changing the user information for username
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]

Step 3: Add new user to sudo group

In the Debian system if you get a member of the sudo group you will get the sudo access. To add a user into the “sudo” group, use the following usermod command:

$ usermod -aG sudo username

Test the sudo access

To check you have sudo access or not, first go to your account login. To this either you login using your username and password or switch to your account using “su” command, as shown below:

$ su - username

Now, run “whoami” command with sudo:

$ sudo whoami

If the user having sudo access, you will get the output of the “whoami” command is “root”:

Output-
root

How to use sudo

To use the sudo privileges with any command is very simple, prefix the command with “sudo” and space as shown below:

$ sudo ls -l /root

In a session, first-time use of “sudo”, you will get a screen to enter the user password:

Output-
[sudo] password for username:

Conclusion

You have learned how to create a new user in Debian System and assign the sudo access or privileges to a user in Debian machine. Now, you can log in into your Debian system or server with your user access and use “sudo” command to run administrative commands.
