Today, what the editor shares with you is the command of Linux to view the process. I believe many people do not know much about it. In order to let you know more about the command of Linux to view the process, I have summarized the following contents for you. Let's look down together. I'm sure you'll get something.

In order to detect and control the process, we must first understand the current process, that is, we need to see the current process running status. On the Linux system, we can use the ps command to view the progress.

Introduction to ps command

The ps (process status) command is the most commonly used process viewing tool under Linux, which can be used to determine which processes are running and running status, whether the process ends, whether the process has zombies, which processes take up too many resources, and so on.

Note: the ps command tool shows the instantaneous status of the process, not the dynamic continuous display. If you want to monitor the process status in real time, you should use the top command.

Ps command options:

-a, view all

-u, displayed in user (user) format

-x, displaying background process running parameters

-ef, which displays all the process information in full format, including the parent process Pid, creator, creation time, and process number. Wait

In a general project, we first need to query a process and delete it with a command

Ps-a | grep helloworld or

Ps-ef | grep helloworld or other

The above is the sharing of Linux's command to view the process, of course, the detailed use of the above differences still have to be used by everyone to understand. If you want to know more, welcome to follow the industry information channel!
