The top command is a commonly used performance analysis tool under Linux, which can display the resource usage of each process in the system in real time , similar to Windows Task Manager.

Usage format:

top [-] [d] [p] [q] [c] [C] [S] [s] [n]

Parameter description:

d: Specify the time interval between every two screen information refreshes. Of course, users can use the s interactive command to change it.

p: Only monitor the status of a certain process by specifying the monitoring process ID.

q: This option will cause top to be refreshed without any delay. If the calling program has superuser privileges, top will run with the highest possible priority.

S: Specify the accumulation mode.

s: Make the top command run in safe mode. This will remove the potential dangers posed by interactive commands.

i: Make top not display any idle or zombie processes.

c: Display the entire command line instead of just the command name.
