How to view the TOP Command-Linux progress

Running the TOP Command in Linux took a long time. I went to this topic and collected it for urgent use!
Tasks: 29 total process count
1. Number of Running Processes of Running
28 sleeping sleep Processes
0 stopped process count
0 zombie botnets
CPU (s): 0.3% us CPU usage
1.0% Sy CPU usage in kernel space
0.0% percentage of CPU used by processes that have changed their priorities in Ni user process space
98.7% ID idle CPU percentage
0.0% wa CPU time percentage waiting for Input and Output
0.0% hi
0.0% Si

Mem: 191272 k total physical memory
Total physical memory used by 173656 K used
17616 K free Free Memory Total
Memory usage of 22052 K buffers as kernel Cache
Swap: 192772 k total number of swap Areas
Total number of swap areas used by 0 K used
192772 K free swap zone total
The total number of swap areas of the 123988 K cached buffer.
The content in the memory is swapped out to the swap zone and then into the memory, but the used swap zone has not been overwritten,
This value indicates the size of the SWAp zone where the content already exists in the memory.
When the corresponding memory is swapped out again, you do not have to write data to the swap zone.

Detailed information about each process is displayed at the bottom of the process information area. First, let's take a look at the meaning of each column.
Serial Number Column name meaning
A pid process ID
B ppid parent process ID
C ruser real User Name
D uid: User ID of the process owner
E User: User Name of the process owner
Group name of the owner of the F group process
The terminal name of the G tty startup process. Processes not started from the terminal are displayed?
H PR priority
I ni nice value. A negative value indicates a high priority, and a positive value indicates a low priority.
The final CPU used by j p is only meaningful in multiple CPU Environments
K % percentage of CPU time used since the last CPU update to the present
L total CPU time used by the time process, in seconds
M Time + the total CPU time used by the process, in the unit of 1/100 seconds
N % mem percentage of physical memory used by the Process
O total virtual memory used by the virt process, in KB. Virt = swap + Res
The swap size in the virtual memory used by the P SWAp process, in KB.
The size of the physical memory used by the Q res process, Not swapped out, in KB. Res = code + Data
R code executableCodePhysical memory occupied, in KB
Physical memory occupied by other parts (Data Segment + stack) except the executable code of S data, in KB
T SHR shared memory size, in KB
U nflt page error count
The number of modified pages that the last write to the present by V.
W s Process status.
D = uninterrupted sleep
R = run
S = sleep
T = tracking/stopping
Z = zombie Process
X command name/command line
Y wchan: if the process is sleep, the system function name in sleep is displayed.
Z flags task flag, refer to sched. h

Unfortunately, there is no explanation for hi and Si.
