Create a user with the "Useradd" or "adduser" command using the shell command "Useradd" and "AddUser" are the same. 　　We'll use the Useradd command to demonstrate how to create a new user. The use of this is the case.

For a computer user, you store, move, and delete files on disk day after day. Of course you care about disk space usage. There is a Shell in Linux that allows users to have a clear picture of how disk space is being used anytime, anywhere. It is the "DF" command. We tried to enter DF in the terminal to see what it would show. Gosh, there's a lot of stuff.

The command format for deleting a group is very simple, and you can enter the name of the group after the Groupdel command. Please try to enter the command in the terminal: Groupdel hello ...

Let's open the system terminal and directly enter LS in the directory to see what it outputs? The original LS command lists all the files and directories in the terminal's current directory. The names we see in blue are directories. Of course, all of these directories may also have subdirectories and files.

It can make the files and directories within the directory show only one per line, I ...

In the figure above, we use the Red line to show the size of each file and directory that occupies the hard drive. The position of the green coil is relative to the name of each file and directory. And the position of the blue circle is the order of the current eye ...

In Linux we already have a very sophisticated graphical interface. However, in many cases, the use of command-control systems is very practical.
