ps aux is the X-ray vision command. Every program, every script, every background daemon — laid out in one big table. The first move when 'something feels slow' or 'something's eating memory'.
In this lesson:
🎯 ps aux — list ALL processes from ALL users
🎯 Reading the columns: USER, PID, %CPU, %MEM, COMMAND
🎯 ps aux | grep nginx — find specific processes (Stage 09 preview!)
🎯 ps --sort=-%cpu | head -10 — top 10 CPU eaters
🎯 ps vs top: snapshot vs live view
