UbuntuLinux user management in the operating system

Article Title: UbuntuLinux user management in the operating system. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

As you have noticed, most of the tasks are easily completed during the daily use of ubuntu. However, when you want to expand your applications on ubuntu, such as using new applications to build a home network and add new users, what will happen? This brief guidance article will share with you some tips, including creating and managing other users and using other tips to verify some key differences, and provides some skills related to the root user. Perhaps the most important thing is that these steps can help you enhance your use of ubuntu systems, making it more than just another personal desktop computer.

　　Chapter 1: understanding users in ubuntu

The security and functionality of your ubuntu system depend heavily on how you assign permissions to users and how to use them. It may be more important to understand how the ubuntu GNU/Linux environment processes users than to analyze the complicated details.

First, when you install ubuntu, you will be asked to create a user account. This initial user account will store related user files in the home file directory, this applies to the users created next, but there are some special things for the first user account you created.

Take me as an example. When I installed ubuntu, I created a "mark" user account. This mark is not only my first ubuntu user, but also automatically assigned special and very powerful permissions that are not available to other users. My mark account can create users, change files and file directories, and complete some administrator functions on ubuntu, these functions are usually completed with another important user account "root.

Therefore, in ubuntu, you should understand the following three key users:
* The initial user created when ubuntu is installed. My name is mark
* Root users generally have the highest permissions and are considered administrators.
* For all other users, I mean the basic users who are added after the installation.

The three types of users mentioned above have their own folders, their own special permissions, and, most importantly, their specific roles in your ubuntu system. In the following section, I will explain how to activate and use them. Let's start with basic users.

Note: Now, I assume that you log on to ubuntu as an initial user, because only in this way can you have the permissions required to perform the following tasks.

　　Chapter 2: create and manage Junior users

When you install ubuntu at home or in the office, it is inevitable that someone else will beg you to let them use the system. Some may want to experience one of the very cool applications installed by default in the system, but some may wish to take a look at the power of GNU/Linux. In other words, you need a good way to grant them the login permissions, but you cannot access the key functions of those systems.

Step 1: use tools for users and groups.

With the user and user group tools, you can easily create a basic user. Method? Open your main menu and see whether the system option is available? Select, and then select the user and group.
Note the following information:

This is a very important piece of information, expressed as a feature of ubuntu. In most GNU/Linux systems, privileged users are usually root, and the password is the password corresponding to root. However, in ubuntu, this privileged user is the initial user you created. Therefore, you must enter the password of this user account.
Once you enter the password, you will have permissions to operate on all kinds of Administrator tools. In the "Understanding Super Users" section, I will further elaborate on the causes.

Step 2: Add a new user

Now you should have seen the user and group tools. Now, please select the Add User button on the right. Your selection of the account groups that you have added depends on what type of users you have added, and what operations you want to perform on your ubuntu. If you just want to add a basic user so that others can access your ubuntu system, the default options can meet this requirement.
For example, I will add my son John as the basic user of my ubuntu system so that he can enjoy some great GNU/Linux games on my computer. The following is the user's sample information. Note that I want to give my son a safe and memorable account, so I chose to manually set the password.
