What are the characteristics of Linux system?
Features of Linux:
1. Open source
Benefits of open source
① Open source software generally has excellent quality when released.
②Open source spirit
③More secure
2. Openness
The system follows world standards specifications, in particular following the Open Systems Interconnection (OSI) international standards.
3. Multi-user
System resources can be used by the same user, and each user has its own resources (for example: files, devices) They have specific permissions and do not affect each other.
4. Multitasking
It is the computer executing multiple programs at the same time, and the operation of each program is independent of each other.
5. Good user interface
Linux provides two interfaces to users: user interface and system call. Linux also provides users with a graphical user interface. It uses facilities such as the mouse, menus, windows, scroll bars, etc. to present users with an intuitive, easy-to-operate, and highly interactive friendly graphical interface.
6. Device independence
The operating system treats all external devices as files. As long as their drivers are installed, any Users can manipulate and use these devices just like files without knowing their specific existence. Linux is a device-independent operating system and its kernel is highly adaptable.
7. Provides rich network functions
The complete built-in network is a major feature of Linux.
8. Reliable security system
Linux has adopted many security technical measures, including read and write control and protected subsystems , audit trails, core authorization, etc., which provide necessary security guarantees for users in network multi-user environments.
9. Good portability
Transfer the operating system from one platform to another so that it can still be used as required. The ability to operate in its own way. Linux is a portable operating system capable of running in any environment and on any platform, from microcomputers to mainframe computers.
Disadvantages
①Linux requires the use of the command line terminal mode for system management. (The maximum limit of popularity)
②No specific supporting manufacturer
③Insufficient support for games
④Insufficient support for professional software

Linux, the full name is GNU/Linux, is a UNIX-like operating system that is free to use and freely disseminated. Its kernel is written by Linus· First released by Benedict Torvalds on October 5, 1991, it is mainly inspired by the ideas of Minix and Unix. It is a POSIX-based multi-user, multi-tasking operating system that supports multi-threading and multi-CPU. It can run major Unix software tools, applications and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance. There are hundreds of different Linux distributions, such as Debian and Archlinux based on community development, and Red Hat Enterprise Linux, SUSE, Oracle Linux, etc. based on commercial development.

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.
