LIUNX Study Notes (1)

As a Linux beginner, limited by the ability and knowledge, there may be many errors or incomplete content in the next writing. These are just my LINUX study notes, for criticism and correction. This is also the first time I have written such an article on technical content. To tell the truth, I don't know where to start, and the related content is very weak.

This is also the first time I wrote such an article on technical content. To tell the truth, I don't know where to start, and the related content is very weak. Although I had a LINUX course for a year before, I didn't pay much attention to it at that time, I just looked at it, But I vaguely remember a few.Command. At this stage, the learning starts completely from scratch. Here, we will sort out the relevant knowledge points based on our understanding based on what the teacher says. As the instructor talked about the large internal capacity and mostly some basic commands, in order not to turn the article into a Linux Command manual, I will summarize some of the common sense, commands, and knowledge points that I think are important.

Linux is a general term for a class of Unix computer operating systems. The Linux kernel is also named "Linux ". There are many different versions of linux pronunciation. Some people combine their pronunciation on the Internet and linux, and summarize several reading methods that they think are the most appropriate and common: /li \ 'n' ^ ks/("renax") or/\ 'li: n э ks/("renax") or/li \ 'nju: ks/("Li neks "). Everyone can understand these issues. Which one is more authentic? Of course, it is the original voice of linux. But in fact, there seem to be a few users who use linux reading methods.

Linux is an open-source software that can obtain its source code for free. Common users generally do not have the ability and conditions to use the source code. Therefore, a special company or organization is required to compile the source code, generate programs available for users. This is the release version of Linux. A typical Linux release includes: Linux core, some GNU libraries and tools, command line shell, graphic interface X Window System and corresponding desktop environments, such as KDE or GNOME, it also contains thousands of applications from office packages, compilers, text editors, and scientific tools. Mainstream releases include ubuntu, debain, and F.EdOra, Gentoo, PCLinuxOS, Slackware, SUSE, CentOS, and Red Hat.

Linux philosophy:

1. Everything is a file

2. Short and single-purpose Program Composition

3. concatenate multiple applets to complete complex tasks

4. Try to avoid capturing user interfaces

5. Saving software configuration information through text files
