How to List Running Processes in Linux (ps aux)

ps aux lists every running process on the system along with its resource usage, owner, and process ID.

Key points

• The PID (process ID) column is what you need to target a process with commands like kill
• %CPU and %MEM columns show each process's current resource usage
• Pipe it to grep to find a specific process: ps aux | grep nginx

Example

ps aux | grep node
