System Information Viewing: Usage of the Ubuntu uname Command

`uname` is a lightweight and practical system information viewing tool in Ubuntu that requires no additional installation. It can quickly obtain basic information such as kernel version, hostname, and hardware architecture, making it suitable for beginners. Basic usage of `uname`: Executing it directly displays the kernel name (default: `Linux`). Common parameter functions: - `-a` (or `--all`): Displays all system information, including kernel name, hostname, kernel version, hardware architecture, and operating system name (e.g., `Linux my-ubuntu 5.15.0-76-generic x86_64 GNU/Linux`); - `-r` (or `--kernel-release`): Displays the kernel release version; - `-n` (or `--nodename`): Displays the hostname; - `-m` (or `--machine`): Displays the hardware architecture (e.g., `x86_64`); - `-v` (or `--kernel-version`): Displays the detailed kernel version; - `-o` (or `--operating-system`): Displays the operating system name (usually `GNU/Linux`). Application scenarios include quickly checking system information, script automation tasks (e.g., adapting software for different architectures), and comparing kernel versions across multiple devices.
