Some top, P ordered by CPU usage, in the footprint of the M in the sorting, c can see detailed command, and then, after you ordering, can according to the first column of the pid, use the ps command to view the process information,
And top - H - p processes, threads can see the process;
Process of lsof -p process, we can see open what file and so on
