Linux Processes System in Linux
Processes are running programs. ps lists processes; ps aux shows all processes with detailed info (user, CPU, memory). top displays live resource usage—CPU, memory, running processes—updated in real time (q to quit). kill terminates a process: kill PID (gracefully) or kill -9 PID (forcefully). df shows disk space usage, du estimates directory sizes. Understanding process management is critical for system administration.
ps aux | grep name finds specific processes. kill %1 terminates job 1. bg and fg control background/foreground jobs. A process consuming too much memory or CPU can be identified via top and stopped with kill. df -h shows human-readable sizes (KB, MB, GB). These tools help troubleshoot performance issues and manage system resources efficiently.
