Introduction to Linux
Linux is a free-to-use and freely distributed Unix-like operating system. It is a multi-user, multi-tasking operating system based on POSIX and UNIX that supports multi-threading and multi-CPU. Linux can run major UNIX tools, applications, and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits Unix's network-centric design philosophy and is a stable multi-user network operating system.
This tutorial series will start from the basics of Linux and gradually delve into advanced concepts, including Linux installation and configuration, file system, command line operations, user and permission management, process management, network configuration, system administration, server configuration, security hardening, and more. Through systematic learning, you will master the core concepts and practical skills of Linux, enabling you to proficiently use and manage Linux systems in various scenarios.
