Essential Linux VPS commands: ls -la (list files), htop (monitor CPU/RAM), df -h (disk usage), ufw status (firewall), systemctl status nginx (web server status), docker ps (running containers), pm2 list (Node.js processes). All work on Ubuntu 24.04 — the default OS on best VPS hosting India like GigaNodes.
