Friendly linux System (1)

There are a lotLinuxIn most cases, a lot of "Blunt" commands are pushed to the reader, so that many people are discouraged and pass by without entering the door. So I imagine a smoother way of learning. Before learning linux commands, you should first learn about linux in a pure language. Just like before the game starts, the first thing we need to do is introduce the game rules. Most beginners are new to Linux. There are often some doubts and problems. We will understand Linux from far and near, from macro to micro.Operating SystemStrong and friendly.

Problem 1: Winows has a registry. Why is there no registry in Linux?

The Registry is the core component of Windows. It configures the entire system. Linux uses the entire file system as the "Registry". The tree structure of the Windows registry can roughly correspond to the tree structure of the Linux File System.

The configuration file in Linux is equivalent to the registry key, or the distributed registry used in Linux.

So why is Linux designed like this? Because Linux is a so-called network operating system, a single computer is not the limit of Linux. If it is a system composed of multiple computers, distributed management has a huge advantage.

For example, damage to a disk containing a configuration file does not paralyze the entire system, but may only invalidate some functions.

Question 2: Windows has a complete graphical interface, and Linux wants to learn the command line.

First, the command line is definitely more advanced than the graphic interface. Command Line is the first interface for programmers, while the graphic interface is the first interface for common users.

Maybe many people may have different opinions. In fact, it is clear that we should move forward.

What is the next evolution of the command line? Voice Control is simple, that is, converting human natural language into commands.

What is the next evolution of the graphic interface? It is pose control. For Windows systems, there are only three positions. Click, double-click, and drag and drop. The more advanced IPad is mobile and circled.

Pose control is simple, easy for users to get started, and voice control is complicated, but the control accuracy is very high.

As programmers, we require computers to do more complex work than normal users, so using command lines is very efficient.

In a back step, the graphical interface is essentially a command line, but it just translates the posture into command execution.

The code programmed by programmers is also "command line", just a single command.

In short, as long as the fear of Linux Command lines can be broken, the next thing will be very easy. This command line is definitely not a command line you just imagined, It is very intelligent.

Question 3: How can I remember there are so many directories and so many commands in Linux?

First, the Linux directory is the soul of the Linux system. All hardware can be abstracted as files to achieve network. (The Internet is just a further evolution of Unix/Linux)

So as long as you have mastered the Linux directory rules, it is much easier to remember on the basis of understanding. In addition, the Linux Command Line provides intelligent functions, allowing you to enter less than 95% characters to complete the command.

It's not what you think of as silly as knocking on a bunch of commands. Those who use Linux are very smart. How can they make themselves work hard?
