How to learn Linux system

Linux system learning methods: 1. Choose a suitable Linux distribution, such as centos, ubuntu, etc.; 2. Learn basic Linux commands; 3. Master the concepts of the Linux operating system; 4. Learn code specifications and Git service for distributed management code.

Linux is a free and open source Unix-like operating system, which was born on October 5, 1991 (the first time it was officially announced to the outside world) , developed by Finnish student Linus Torvalds and many enthusiasts who joined later. Compared with Windows, open source is its unique feature. This feature allows it to give you more permissions to achieve things that cannot be achieved on Windows. Of course, learning Linux will play a decisive role in helping you enter the IT industry.

How to learn Linux? For many people, it is another headache.

1. Choose a more suitable Linux distribution.

There are many kinds of Linux distributions, some of which are provided for specialized businesses and some for individual users. Fedora is a community version based on RHEL, CentOS, Scientific Linux, and Oracle Linux. Fedora packages significantly more software packages than RHEL. One reason is that a diverse community is involved in building Fedora; it's not just one company. The relationship between SUSE, SUSE Linux Enterprise Server (SLES), and openSUSE is similar to the relationship between Fedora, Red Hat Enterprise Linux, and CentOS. Debian is the upstream for many distributions, including Ubuntu, which in turn is the upstream for Linux Mint and other distributions. Debian is widely used in servers and desktop computers. Debian is a purely open source project and focuses on one key point, stability. It also provides the largest and complete software repository to users. I personally recommend that you learn redhat, because Redhat is reliable and the kernel is relatively stable. I suggest you read "This is How You Should Learn Linux", which is based on Redhat.

2. Learn some basic commands.

What’s special about the Unix & Linux command line is that the design of some options follows tradition. You only need to know one to use similar functions in other commands. Options are usually English abbreviations of related functions, not meaningless English words. In addition to some basic commands, you need to master them. Like ls cd cat more mkdir rmdir vi rm tail ./ or sh. You also need to look at the subsequent parameters.

3. Master some basic concepts of operating systems.

For a senior programmer, they can make good use of the interfaces left by the operating system to perform deep programming. For example, multi-thread programming is to use the resources of the CPU to implement related programs. However, as a As a relatively qualified programmer, you must master these. Things like inter-process communication, file operations, multi-thread programming, sock programming, etc., must be mastered proficiently, so that you can perform the following operations, learn some big data, UI development, etc. However, you will find that after learning this, Learning new things on your own makes it easier to get started.

4. Learn code standards and git service for distributed management code.

A qualified IT industry personnel must be very organized about their coding. This is not only neat and easy to maintain, but you must know that the code of a project has more than tens of thousands of lines. , if it is not adjusted, how about subsequent maintenance and so on. Another point is to learn code management. Git is a good tool that allows you to quickly implement code management.
