Linux
1. Linux: There are dozens of file system types: ext2, ext3, ext4, xfs , brtfs, zfs (man 5 fs can get an introduction to all file systems)
Different file systems use different methods to manage disk space, each with its own advantages and disadvantages; the file system is specific to the partition, so formatting Targeted at partitions, partition formatting refers to the process of registering and indexing partition space using specified file system types and establishing corresponding management tables.
ext2 has extremely fast speed and minimal CPU usage, and can be used for hard disks and mobile storage devices
ext3 adds log function and can be traced back
ext4 Log style The file system supports 1EB (1024*1024TB), with a maximum single file of 16TB. It supports continuous writing to reduce file fragmentation. The default file system of rhel6
xfs can manage a 500T hard drive. rhel7 default file system
brtfs file system is optimized for solid state disks,
zfs update?
Note: EXT (Extended file system) is an extended file system and extended file system. ext1 was released in April 1992 and was the first file system made for the Linux core.
Format command:
mkfs -t <文件系统类型> <分区设备文件名> mkfs.xfs /dev/sdb1
man 5 fs can obtain a brief introduction to all file systems
Maximum supported files and other information?
windows
FAT16: The disk partition format used by MS-DOS and win95, using a 16-bit file allocation table, only supports 2GB Disk partition, the maximum single file is 2GB, and the disk utilization is low
FAT32: (i.e. Vfat) uses a 32-bit file allocation table, supports a maximum partition of 128GB, a maximum file of 4GB
NTFS: supported The maximum partition is 2TB and the maximum file is 2TB. The security and stability are very good and file fragmentation is not prone to occur.
Others
RAMFS: Memory File System
ISO 9660: Optical Disc
NFS: Network File System
SMBAFS/CIFS: Network file system that supports Samba protocol
Linux swap: swap partition to provide virtual memory.

The 5 Core Components of the Linux Operating SystemMay 08, 2025 am 12:08 AMThe five core components of the Linux operating system are: 1. Kernel, 2. System libraries, 3. System tools, 4. System services, 5. File system. These components work together to ensure the stable and efficient operation of the system, and together form a powerful and flexible operating system.
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.

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),
