Process & Services

Process and service management: monitoring (ps, top), signals (kill), priorities (nice/renice), service management (systemctl), scheduling (cron), logs (journald).

Content in development

Planned:

ps aux / ps -ef — process snapshot, filtering
top / htop — interactive monitoring, hotkeys
kill / killall / pkill — sending signals; SIGTERM vs SIGKILL
nice / renice — CPU priority (nice -20..19)
systemctl — start/stop/enable/status/mask, unit files
journalctl — filter by unit, time, priority
cron / crontab — syntax, special strings (@reboot, @daily)
at / anacron — one-time tasks
