Straightforward reference for the Linux sysadmin commands you reach for daily but don't always remember the flags for. Covers system info checks, resource monitoring with tools like top and sar, systemd service management, and quick troubleshooting workflows. The scenarios section is genuinely helpful, like the health check one-liner that runs uptime, free, df, and lists failed services in sequence. Nothing groundbreaking here, just a clean cheatsheet that saves you from googling "iostat syntax" for the hundredth time. Works best as a quick lookup when you're SSH'd into a box and need to figure out why it's dragging.
