The main uses of Linux include: 1. Server operating system, 2. Embedded system, 3. Desktop operating system, 4. Development and testing environment. Linux excels in these areas, providing stability, security and efficient development tools.

The Internet does not rely on a single operating system, but Linux plays an important role in it. Linux is widely used in servers and network devices and is popular for its stability, security and scalability.

The core of the Linux operating system is its command line interface, which can perform various operations through the command line. 1. File and directory operations use ls, cd, mkdir, rm and other commands to manage files and directories. 2. User and permission management ensures system security and resource allocation through useradd, passwd, chmod and other commands. 3. Process management uses ps, kill and other commands to monitor and control system processes. 4. Network operations include ping, ifconfig, ssh and other commands to configure and manage network connections. 5. System monitoring and maintenance use commands such as top, df, du to understand the system's operating status and resource usage.

Introduction Linux is a powerful operating system favored by developers, system administrators, and power users due to its flexibility and efficiency. However, frequently using long and complex commands can be tedious and er

Linux is suitable for servers, development environments, and embedded systems. 1. As a server operating system, Linux is stable and efficient, and is often used to deploy high-concurrency applications. 2.
