Linux Learning (1) Add new users under unbuntu, linuxunbuntu

I recently installed a dual-system and started to work with unbuntu. Linux is a multi-user operating system. Many operations require administrator permissions. All administrator permissions are very important, for beginners, we 'd better use the permissions of a general user. Compared with beginners, we do not know much about many things. If we use an administrator privilege, it is likely to cause many irreversible effects. Then, we added a standard user to meet our general needs for learning.

Step 1: Go to system settings and find the user account options:

Step 2: Unlock the current user:

Step 3: after unlocking, we can add new users:

Step 4: Create a new user;

Here, we can create a new user. Switch the user and use the new user. This user is only a standard user. We still need to obtain permissions for some operations.

Linux is not a language. linux is the most strict type of operating system kernel, rather than an operating system. Of course, linux is now collectively referred to as an operating system with linux as the kernel. Ubuntu is an operating system with linux as the kernel. Linux is very different from windows. If you take the first step, I think you should first learn to use this operating system, as you are familiar with windows, linux involves many terminal operations. Although the so-called terminal seems to be similar to the command interpreter cmd in windows, it is essentially different, linux terminals can be called external interfaces of the kernel, while windows cmd only simulates dos. You can use the terminal to almost control the entire ubuntu system, but in windows, cmd can only do some very limited operations. More importantly, all linux Kernel Operating Systems have almost the same terminal operations.
You will certainly encounter many problems when using ubuntu. You should first learn to solve these problems and then think more deeply about things and use more terminal operations.
