ps command The following 4 columns of information are displayed by default:
PID: The process number of the running command (CMD)
TTY: The location (terminal) where the command is run
TIME: Running The CPU processing time occupied by the command
CMD: The command run by the process
2. Then check the occupied port through pid
netstat -nap | grep 进程pid

The 5 Essential Elements of Linux: ExplainedMay 07, 2025 am 12:14 AMThe five core elements of Linux are: 1. Kernel, 2. Command line interface, 3. File system, 4. Package management, 5. Community and open source. Together, these elements define the nature and functionality of Linux.
Linux Operations: Security and User ManagementMay 06, 2025 am 12:04 AMLinux user management and security can be achieved through the following steps: 1. Create users and groups, using commands such as sudouseradd-m-gdevelopers-s/bin/bashjohn. 2. Bulkly create users and set password policies, using the for loop and chpasswd commands. 3. Check and fix common errors, home directory and shell settings. 4. Implement best practices such as strong cryptographic policies, regular audits and the principle of minimum authority. 5. Optimize performance, use sudo and adjust PAM module configuration. Through these methods, users can be effectively managed and system security can be improved.
Linux Operations: File System, Processes, and MoreMay 05, 2025 am 12:16 AMThe core operations of Linux file system and process management include file system management and process control. 1) File system operations include creating, deleting, copying and moving files or directories, using commands such as mkdir, rmdir, cp and mv. 2) Process management involves starting, monitoring and killing processes, using commands such as ./my_script.sh&, top and kill.
Linux Operations: Shell Scripting and AutomationMay 04, 2025 am 12:15 AMShell scripts are powerful tools for automated execution of commands in Linux systems. 1) The shell script executes commands line by line through the interpreter to process variable substitution and conditional judgment. 2) The basic usage includes backup operations, such as using the tar command to back up the directory. 3) Advanced usage involves the use of functions and case statements to manage services. 4) Debugging skills include using set-x to enable debugging mode and set-e to exit when the command fails. 5) Performance optimization is recommended to avoid subshells, use arrays and optimization loops.
Linux Operations: Understanding the Core FunctionalityMay 03, 2025 am 12:09 AMLinux is a Unix-based multi-user, multi-tasking operating system that emphasizes simplicity, modularity and openness. Its core functions include: file system: organized in a tree structure, supports multiple file systems such as ext4, XFS, Btrfs, and use df-T to view file system types. Process management: View the process through the ps command, manage the process using PID, involving priority settings and signal processing. Network configuration: Flexible setting of IP addresses and managing network services, and use sudoipaddradd to configure IP. These features are applied in real-life operations through basic commands and advanced script automation, improving efficiency and reducing errors.
Linux: Entering and Exiting Maintenance ModeMay 02, 2025 am 12:01 AMThe methods to enter Linux maintenance mode include: 1. Edit the GRUB configuration file, add "single" or "1" parameters and update the GRUB configuration; 2. Edit the startup parameters in the GRUB menu, add "single" or "1". Exit maintenance mode only requires restarting the system. With these steps, you can quickly enter maintenance mode when needed and exit safely, ensuring system stability and security.
Understanding Linux: The Core Components DefinedMay 01, 2025 am 12:19 AMThe core components of Linux include kernel, shell, file system, process management and memory management. 1) Kernel management system resources, 2) shell provides user interaction interface, 3) file system supports multiple formats, 4) Process management is implemented through system calls such as fork, and 5) memory management uses virtual memory technology.
The Building Blocks of Linux: Key Components ExplainedApr 30, 2025 am 12:26 AMThe core components of the Linux system include the kernel, file system, and user space. 1. The kernel manages hardware resources and provides basic services. 2. The file system is responsible for data storage and organization. 3. Run user programs and services in the user space.

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. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
