PR: Priority level of processes
NI: Priority level value of the process
VIRT: Virtual memory value occupied by processes
RES: The physical memory value occupied by the process
SHR: Shared memory value used by processes
S: The state of the process, where S represents sleep, R represents running, Z represents dead state, and N represents a
negative priority value for the process
%CPU: The CPU usage rate occupied by the process
%MEM: The percentage of physical memory and total memory occupied by the process
TIME+: The total CPU time occupied by the process after startup
COMMAND: The name of the startup command used to start the process
