![]() ![]() Typically, these privileges are only accessible to the root user. You may verify the creation of the new user by checking the content of the /home directory or grep on the username in /etc/passwd file. With the sudo command, you can grant certain users special administrative privileges. After confirmation, the user will be created successfully. ![]() You may enter the details if you want to, but it is not mandatory. It also asks for details for name, phone numbers, and others. With the adduser command, the home directory for the user is also created. What you’ll need A running instance of Linux A user with sudo privileges How to create a sudo-able user on Ubuntu Server First, we’ll demonstrate how this is done on Ubuntu Server. Here's a sample screenshot for the creation of a new user named handbook: You may also use Ctrl+U Linux shortcut to delete the entire line and start from the beginning. When you type your password, it will be invisible, but you can also use delete or backspace whenever you like. You can read the difference between adduser and useradd here. You can either adduser or useradd command for adding a new user. This is to ensure that only people who are having rights over the system or in charge of protecting the system are creating new users and nobody else. To create a user, one must be a sudoer or a root. Note: Adding a new user will also create a user group named the same as the user in Ubuntu. You add it to the sudoer list in the next step. Keep in mind that the user will be a regular user when you create it. If the user that you want to grant sudo access doesn't exist, the first step would be to create that user. Please check the users present on your Linux system. As root, create a new sudoers.d directory under /etc/: mkdir -p /etc/sudoers.d/ Create a new file in the /etc/sudoers.d directory: visudo -f /etc/sudoers. Let’s now get started on creating a sudo user or sudoer in Linux command line. However, I am not sure if all Linux distributions have a group named sudo. The commands used here are standard Linux commands and these should be installed on most Linux distributions by default. I am using Ubuntu in this tutorial, but the steps mentioned here should apply to Debian and many other Linux distributions as well. That was too short, right? Don't worry! I explain the steps in detail. I'll just show how you can add a sudo user to Ubuntu or Debian. In Ubuntu and Debian-based Linux systems, sudo is practically synonymous with root but in reality, sudo is much more than that.īut I am not going to go into details on sudo here. You just add sudo before the command to run it with root privilege. You don't need to know the root password or switch to root user. This can be done by logging out and back in again.As a sudo user, you can run commands and access files as root user but with your own password. Once this has been given to the user you will need to reload the group permissions. You will need to replace chewett with the user you want to add sudo privileges to. This user is configured by default to have the sudo privilege. This command requires running as root so you will either need to log in as root or use the pi user. This can be achieved running the following command. You can create a new user with the adduser command as a root user. To allow a user to run sudo on Raspbian OS you can add them to the group sudo group. However if you create a new Linux user on Raspbian you may want to give it sudo access. The default pi user on Raspbian OS will have been given sudo access. This gives both an appropriate level of security and flexibility with running your computer. ![]() This means that any commands you need to run as the superuser, you can prefix with sudo but otherwise you run as your user. Once you have finished running your command with sudo it will return to running as your user. Sudo allows you to run a single or multiple commands as the superuser. Since there will always be times you will want to run something with superuser rights sudo can help. If you accidentally run a malicious script then it will have rights to do anything on your computer unhindered. If you run everything as root then anything you run also has these rights. In addition to accidental issues, there are also malicious programs to consider. This could be you purposely (and wrongly) modifying files or a program you run accidentally changing them. There are a lot of files you will not want to edit or remove as doing so would cause issues for the computer. Running as root will let you change/delete any files on the filesystem. There are a number of reasons for this and the primary one is security. Instead of logging in as the root user and running your commands it is recommended to use sudo. The super user’s username is typically root on Linux machines. Sudo is a command that lets you run a command as the “Super User”. ![]() This blog post describes how you can enable sudo for any user on the Raspberry Pi OS, Raspbian. ![]()
