Process & Resource Monitoring (Top/Htop/Ps/Systemd)

Pinpoint Memory Hogs with ps Sort

🧩 The Challenge

Identifying which specific processes are consuming the most resident set size (RAM) without the overhead of an interactive terminal UI.

💡 The Fix

Use the ps command with custom sorting flags to extract and rank processes based on their memory footprint.

ps aux --sort=-rss | head -n 11

⚙️ Why It Works

The –sort flag allows for dynamic reordering of the process table, and the negative sign indicates a descending order, effectively bubbling the most memory-intensive processes to the top of the list.

🚀 Pro-Tip: Use –sort=-%cpu to perform the same ranking operation based on processor utilization instead of memory.
