What is the purpose of the linux command? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The linux command is a command that manages the Linux system. For the Linux system, no matter the CPU, memory, disk drive, keyboard, mouse, or users are all files, the commands managed by the Linux system are the core of its normal operation, similar to the previous DOS commands.

There are two types of linux commands on the system: the built-in Shell command and the Linux command.

First of all, we introduce the term "console (console)", which is the man-machine interface that we usually see using character interfaces, such as dos.

When we say console commands, we refer to the commands that can be entered by the operating system through the character interface, such as the dos command. What we need to understand is the basic console commands based on the Linux operating system.

It is important to note that unlike dos commands, Linux commands (including file names, etc.) are case-sensitive, that is, if you enter the wrong command case, the system will not respond as you expect.

Mode switching

1. From graphic to character # logout or init 3

2. From character to graphical interface init 5

3. Quit consolelogout or exit or ctrl+d

4. Log out of Ctrl + Alt + Backspace

5. Power off # poweroff or init 0 or shutdown-h now or halt-p

6. Restart # reboot or init 6 or shutdown-r now

If your English is good enough, you can master linux without anyone, as long as you can use man. Man is actually a help for viewing instruction usage. The most important thing to learn about any kind of UNIX operating system is to learn to use man as an auxiliary command.

Man is an acronym for manual (manual). Its description is very detailed, but because it is all in English, it looks like a headache. It is recommended that you go to see man when you need it. Normally, just remember some basic usage.

This is the answer to the question about the role of the linux command. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
