A single-file interactive reference covering the most important Linux troubleshooting and administration commands, organized into eight sections: Network, CPU & Memory, Security, Storage, Systemd, Kernel & Hardware, Backup & Recovery, and Containers & Virtualization.
Each command card is expandable and includes practical examples with inline comments, difficulty badges (recommended / advanced / deprecated), and a direct link to the official documentation.
