Master Linux Process Management: Powerful ps Commands and Visual Tips

(1) Show all processes:

ps -ax | less

(2) Show processes of a specific user (e.g., root): ps -u root (3) Filter processes by CPU and memory usage:

ps -aux | less

(4) Sort processes in descending order by CPU or memory, and combine sorts to show the top 10 results:

ps -aux --sort -pcpu | less

ps -aux --sort -pmem | less

ps -aux --sort -pcpu,+pmem | head -n 10

(5) Display processes in a tree view:

ps -axjf

Alternatively, use the dedicated pstree command for a hierarchical process tree.
