The reason for mastering Linux operations is its wide range of application scenarios and powerful functions. 1) Linux is suitable for developers, system administrators and technology enthusiasts, and is used in server management, embedded systems and containerization technologies. 2) Learning Linux can start with file system structure, shell usage, user permission management and process management. 3) The Linux command line is its core tool, which executes commands through the shell, such as ls, mkdir, cd, etc., and supports redirection and pipeline operations. 4) Advanced usage includes writing automated scripts, such as backup scripts, using tar commands and conditional judgments. 5) Common errors include permissions, paths and syntax issues, which can be debugged through echo, set-x and $?. 6) Performance optimization suggestions

The five pillars of the Linux system are: 1. Kernel, 2. System library, 3. Shell, 4. File system, 5. System tools. The kernel manages hardware resources and provides basic services; the system library provides precompiled functions for applications; the shell is the interface for users to interact with the system; the file system organizes and stores data; and system tools are used for system management and maintenance.

In Linux systems, maintenance mode can be entered by pressing a specific key at startup or using a command such as "sudosystemctlrescue". Maintenance mode allows administrators to perform system maintenance and troubleshooting without interference, such as repairing file systems, resetting passwords, patching security vulnerabilities, etc.

Linux beginners should master basic operations such as file management, user management and network configuration. 1) File management: Use mkdir, touch, ls, rm, mv, and CP commands. 2) User management: Use useradd, passwd, userdel, and usermod commands. 3) Network configuration: Use ifconfig, echo, and ufw commands. These operations are the basis of Linux system management, and mastering them can effectively manage the system.
