Linux for Beginners: Linux Processes, ps, top, and kill | Lesson 6

▶ Linux for Beginners Playlist:    • Linux. Begginer course.   In this lesson, we learned how processes work in Linux and how to monitor the system in real time. We covered PID, parent and child processes, the difference between a process and a service, and commands like ps, top, htop, kill, nice, renice, bg, and fg. We also checked memory, system load, and logs with free -h, vmstat, uptime, dmesg, systemctl status, and journalctl. This lesson gives you a practical foundation for understanding what is happening in Linux right now. Commands used in this lesson: ps aux — shows the list of running processes ps aux | grep bash — finds specific processes in the process list systemctl status service_name — shows the current status of a service top — shows live system activity and running processes in real time htop — a more user-friendly interactive process viewer kill PID — sends the default TERM signal to a process kill -15 PID — sends the TERM signal for a normal stop kill -9 PID — forcefully stops a process with the KILL signal kill -l — shows the list of available signals nice -n 10 command — starts a command with lower CPU priority renice 10 -p PID — changes the priority of an already running process bg — continues a paused process in the background fg — brings a background process back to the foreground free -h — shows memory usage in a human-readable format vmstat — shows a short summary of system state vmstat 1 — refreshes system statistics every second df -h — shows disk space usage on file systems du -sh some_directory — shows the size of a specific directory uptime — shows system uptime and load average dmesg — shows kernel messages dmesg | tail — shows the latest kernel messages journalctl -xe — shows the system journal with useful troubleshooting details journalctl -u service_name — shows logs for a specific service #Linux #Ubuntu #DevOps
