Linux is a set of Unix-like operating systems that are free to use and freely disseminated. It is a multi-user, multi-task, multi-threading and multi-CPU based on POSIX and UNIX. operating system.

It can run major UNIX tool software, applications and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance.

The Linux operating system was born on October 5, 1991 (this is the first time the date was officially announced to the outside world). There are many different Linux versions of Linux, but they all use the Linux kernel. Linux can be installed on a variety of computer hardware devices, such as cell phones, tablets, routers, video game consoles, desktop computers, mainframes, and supercomputers.

It is called plain text file because The content can be read directly, such as numbers, letters, etc. Setting files almost always belong to this file type. For example, use the command "cat ~/.bashrc" to see the contents of the file (cat reads the contents of the file).

2. Binary files: The system actually only recognizes and can execute binary files. Executable files in Linux (scripts, text batch files are not counted) are in this format. For example, the command cat is a binary file.

3. Files in data format (data): Some programs will read files in certain formats during operation. Those files in specific formats can be called data files.

For example, when a user logs in, Linux will record the login data in the /var/log/wtmp file. This file is a data file that can be read out through the last command. But when using cat, garbled characters will be read. Because it is a file in a special format.
