This article mainly introduces how to view the system process in linux, which has a certain reference value and can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

Linux View system processes can be viewed through ps: ps is the most basic but also very powerful process view command, which can be used to determine which processes are running and running status, whether the process ends, whether the process is dead, which processes occupy too much resources, and so on.

Common parameters of the ps command:

A show all processes

-a displays all programs under the same terminal

-A displays all processes c displays the real name of the process

-N reverse selection

-e equals "- A"

E display environment variables

F shows the relationship between programs

-H shows the tree structure

R displays the progress of the current terminal

T displays all the programs of the current terminal

U specify all processes of the user

You can view all the processes of the system with the command "ps-eFH", where the parameters mean:

UID: process owner ID

PID: process ID

PPID: parent process ID

SZ: the page size of the core image of the process

C:cpu scheduling situation

RSS: actual amount of memory consumed by the process (in 1KB)

PSR: the logical processor number of the processor that binds the kernel thread

STIME: the start time of the process

TTY: on which terminal the process runs

TIME: the total amount of time taken up by the process in CPU

CMD: the command to start the process

View all the processes of the system through the command "ps aux", where the parameters mean:

USER: process owner

PID:pid

% CPU: occupied cpu utilization

% MEM: memory usage occupied

VSZ: virtual memory set

RSS: resident memory set

TTY: whether the program is executed for login (tty1-tty6, local login, remote login if pts or?)

STAT: status of the process

START: program start time

TIME: the time for the program to run

COMMAND: the instruction executed.

Thank you for reading this article carefully. I hope it is helpful for everyone to share how to view the process of the system in linux. At the same time, I also hope that you can support us, pay attention to the industry information channel, and find out if you encounter problems. Detailed solutions are waiting for you to learn!
