System OS and Architecture Detection

This document provides commands to check the operating system and CPU architecture on Linux

Linux Commands

Open a terminal and run the following commands:

Check OS Name and Version

uname -s   # Shows the OS name (e.g., Linux)
uname -r   # Displays the kernel version
cat /etc/os-release  # Provides detailed OS information

Example Output:

Linux
5.15.0-84-generic
PRETTY_NAME="Ubuntu 22.04 LTS"

Check CPU Architecture

uname -m    # Shows the machine hardware name (e.g., x86_64, aarch64)
lscpu | grep "Architecture"  # More detailed CPU info

Example Output:

Architecture: x86_64

Common Architecture Outputs

Architecture	Description
x86_64 / amd64	64-bit Intel/AMD CPU (most desktops, servers)
aarch64 / arm64	64-bit ARM CPU (Raspberry Pi, Apple M1/M2, some servers)
armv7l / armhf / arm	32-bit ARM CPU (older Raspberry Pi, embedded devices)

Use these commands to determine your system's OS and architecture type. 🚀
