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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages.
