How to Check System Information in Linux (uname)

uname prints information about the current system, including the kernel name, version, and machine architecture.

Key points

• uname -a prints all available system information in one line
• uname -r prints just the kernel release version, often needed when installing kernel-specific packages
• uname -m prints the machine hardware architecture, like x86_64 or aarch64

Example

uname -a
