Simple process management in Linux

Simple process management in Linux =============================== Commands you will be familiar with this tutorial: ps -- It is one of the important utilities for system administration under process monitoring kill -- kill command in Linux is a built-in command which is used to terminate processes manually. Let’s go to how "ps" command is used in day to day monitoring operations 1. List All Processes in Current Shell ps 2. Display every active process on a Linux system ps -Af or ps -ef 3. Display the processes owned by you ps -x 4. Display every processes running with root user privileges ps -U root -u root 5. Display processes owned by a certain group ps -fG apache ps -fG 48 6. Display processes by PID ps -fp 1178 7. Display process by PPID ps -f --ppid 1154 8. Print process Tree ps -e --forest ps -f --forest -C sshd 9. Show custom output format of a specific PID with pid,ppid,fgroup,ni,lstart,etime ps -p 1154 -o pid,ppid,fgroup,ni,lstart,etime 10. Find a process name using its PID. ps -p 1154 -o comm= 11. Find top running processes by highest memory and CPU usage ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%mem | head ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%cpu | head 12. To kill a Linux processes/unresponsive applications or any process that is consuming high CPU time. First, find the PID of the unresponsive process or application. ps -A | grep -i stress kill -9 2583 2584 13. Perform Real-time Process Monitoring Using Watch Utility watch -n 1 'ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%mem | head'
