This article mainly explains "how beginners quickly master Linux operation and maintenance". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how beginners quickly master Linux operation and maintenance.

First, start from the command, start from the foundation

Often some friends want to build a website as soon as they come into contact with Linux, but they never think of knowing the foundation of Linux first. This is quite difficult. Although Linux desktop applications are developing rapidly, commands still have a strong vitality in Linux. Linux is an operating system composed of the command line, the essence of which is on the command line. No matter what level the graphical interface develops, the principle will not change. Linux commands have many powerful functions: from simple disk operations, file access, to complex multimedia image and streaming media file production. Here, the author divides the most important and most frequently used commands into several parts according to their role in the system. Through the study of these basic commands, we can further understand the Linux system:

● installation and login commands: login, shutdown, halt, reboot, mount, umount, chsh

● file processing commands: file, mkdir, grep, dd, find, mv, ls, diff, cat, ln

● system management related commands: df, top, free, quota, at, lp, adduser, groupadd kill, crontab, tar, unzip, gunzip, last

● network operation commands: ifconfig, ip, ping, netstat, telnet, ftp, route, rlogin rcp, finger, mail, nslookup

● system security related commands: passwd, su, umask, chgrp, chmod, chown, chattr, sudo, pswho

Choose a good Linux book

In various Linux forums, the most common question we see is often a novice, who starts to ask a specific question in the process of installing or using linux, many of which are repetitive, and many people are not even very clear about the basic problem description. This shows that many beginners of linux have not yet mastered the basic skills. How can we quickly improve the basic skills of linux? The most effective way is to learn the authoritative linux reference books, which are very important to learners. A reference book with misconceptions can lead beginners astray. At present, there are many books about linux in China, but there are not many fine ones. The author strongly recommends reading "Bird Brother's Linux Private Cuisine Foundation", which is now in the third edition. Beginners had better buy a paper book to study carefully and make good study notes. Of course, if you are used to reading e-books, you can also download PDF e-books here.

Get into the habit of working under the command line

Be sure to get into the habit of working on the command line, knowing that X-window is just an application running in command-line mode. Although the progress of learning under the command line is slow at first, after you are familiar with it, your future learning path will increase exponentially. From the network administrator's point of view, the command line is actually a rule, which is always effective and flexible. Even through a slow modem line, it can operate a remote system thousands of kilometers away.

4. Think about Linux with Unix thinking

Because Linux is designed with reference to the idea of Unix, understanding and mastering it must be carried out with the thinking of Unix, not with Windows thinking. There is no denying that a large part of windows's success in the market lies in the uniqueness of technical ideas. However, this innovation is carried out in the face of individual users, and in the face of enterprise-level service applications, it is still somewhat inadequate. For many years, the two have been dominant in the field of computer operating systems: unix in the field of servers and Windows in the field of individual users. Thus it can be seen that the user demand determines the operating system used. Whatever the reason, if you want to learn Linux, you must first drag your mind out of the "this river" of Windows and into the ocean of Unix.

5. Learn shell

For Shell (Chinese name shell), readers who are used to Windows must be very strange, because Windows has only one "Shell" (if it can be said to be Shell), and that is Windows itself. The easy-to-understand explanation in one sentence is that shell is an intermediary between user input commands and system interpretation commands. To put it most intuitively, an Shell has its own set of commands. To give an easy-to-understand example, Linux's standard Shel is Bash Shel;Solaris 's shell and B shell;Linux 's Shell is represented on the command line. Readers may not understand that Windows has "evolved" from the command line to the graphical interface, so isn't it a step backwards for Linux to still use the command line now?

I had this idea when I first met Linux. However, it was later found that if you use a graphical interface, fewer resources are allocated to the application software, and it is very important to be able to achieve the same function with a lower hardware configuration on expensive servers.

The following example shows that a server has 1GB memory, and assuming that 512MB is used to handle the graphical interface, the only way to install a database software that requires 784MB memory is to expand the memory. But if you use the command line, the system may only need 64MB memory, and the rest of the memory will be available for database software. Using the command line, not only memory, but also CPU and hard disk and other resources will be saved a lot. Therefore, using the command line as a server is an advantage rather than a disadvantage. Since Shell has so many advantages, we must learn from it.

At this point, I believe that "beginners how to quickly master Linux operation and maintenance" have a deeper understanding, might as well come to the actual operation of it! Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
