Htop Common Interactive Commands

M: in Memory Sort

P: in CPU Occupation ratio Sort

T: in CPU time-consuming sorting

u: filter only shows processes for selected users:

S: tracks system calls initiated by the selected process;

L: displays files opened by the specified process

T: Show Process tree format

A: binds the selected process to the specified CPU on
