Linux was written by LinusTorvalds, a student of the University of Finland, using the Minix operating system as the development platform from the end of 1990 to 1991. At present, it is a UNIX-compatible operating system developed and maintained by enthusiasts all over the world, and it is also a free and open source Unix-like operating system. The logo and mascot of Linux is a lovely and friendly penguin named Tux. Now, with the rapid expansion of Linux applications, more and more friends are beginning to come into contact with Linux. Most of us are used to using Windwos. At this time, we often feel at a loss and don't know where to start. Here is an introduction to how I went from being an ignorant rookie to being an old bird in Linux. The most important thing is to choose a good reference book. Please refer to: https://www.linuxprobe.com/chapter-00.html

I. the characteristics of Linux

1. Openness: the system follows the world standards and specifications, especially the open systems interconnection (OSI) international standard.

2. Multi-user: system resources can be owned and used by different users, and each user has his own resources.

3. Multitasking: the computer executes multiple programs at the same time, and each program runs independently of each other.

4. Good user interface: Linux provides users with two kinds of interface: user interface and system call. Linux also provides a graphical user interface for users. It uses mouse, menu, window, scroll bar and other facilities to present users with an intuitive, easy to operate, interactive and friendly graphical interface.

5. Device independence: the operating system treats all external devices as files. As long as their drivers are installed, any user can manipulate and use these devices as if they were files. Without knowing their specific form of existence. Linux is a device-independent operating system. Its kernel is highly adaptable and provides rich network functions. Perfect built-in network is one of the major features of Linux.

6. Reliable security system: Linux adopts many security technical measures, including read and write control, protected subsystem, audit tracking, core authorization, etc., which provides necessary security guarantee for users in the network multi-user environment.

Good portability: the ability to move an operating system from one platform to another so that it can still run in its own way. Linux is a portable operating system that can run in any environment and on any platform, from microcomputers to mainframes.

8. Free software: users can obtain it and its source code without paying any fee, and its source code can continue to spread without restriction and can be modified, enriched and developed. The original intention of developers is to work together to create a perfect, ideal and free operating system.

2. Rookies have to start with the basics

I often see friends ask some questions in Linux forums, but most of them are very basic. These problems are actually very simple, as long as you have a little understanding of the basics of Linux, you should be able to easily solve these problems. And some friends often want to build a website as soon as they come into contact with Linux, but they don't want to know the basis of Linux at all, which is very difficult. First of all, Linux must learn commands. Although Linux desktop applications are developing rapidly, commands still have strong vitality in Linux. Linux is a command-line operating system, no matter what level of graphical interface development, its essence is in the command line, this principle will not change. Linux command has very powerful functions: from simple disk operation, file access, to complex multimedia image and streaming media file production. It is very important to choose a Linux distribution that suits you. At present, there are more than 100 Linux distributions in the world, and more than a dozen common versions can be found in China. As for which one to choose and how to choose according to your own needs and abilities, the network administrator's best choice is Redhat Linux and Debian Linux,Linux command Daquan: https://www.linuxcool.com/ if the English is not very good, it is more suitable to choose the Chinese version of Red Flag Linux and winning bid Linux.

Third, old birds are all out of practice.

To strengthen your Linux skills, you can only achieve it through practice. So find a computer immediately, install a Linux distribution quickly, and start exploring the wonderful world of Linux. Believe that in this way your own Linux skills will certainly have a big rise. In addition, the human brain is not like a computer's hard disk, unless the hard disk is broken or the data is erased by you, the stored data will be remembered in the hard disk forever and immediately. In the curve of human memory, you have to practice over and over again to remember something clearly and thoroughly. Therefore, it is the same when learning Linux. If you can't review and operate frequently, if you haven't learned the latter, the former will be forgotten. After you are familiar with the Linux command, you can start to build your own small Linux network, which is the best practice, without one. In short, you should do more on your own, and don't always wait for others to teach you and help you solve your problems.
