Graphical Linux commands: Displaying system processes with the top command

What is a process? Simply put, the system is running the program. What if we want to know which programs are running in the current system? It's easy to use the top command to get what you want. We enter in the terminal: top, see what is displayed?

Wow, so many programs are running in the system (each line represents a program)? What do the above columns mean?

The pid:pid is the number that the system is assigned to per program, or process itself. Because the system has to track it after the program is started, why? Because at least we have to find it and turn it off. Is there a program that is open and not closed? It seems that no software is more wicked than "Trojan Horse". But the advantage of this command is that if the Trojan is running, it will also appear in the top command.

USER: Maybe friends will know what this column means when they look at the name? That's right. This column shows the program, or which user started the process.

Time+: Refers to how long the program or process has been running.

COMMAND: This is simpler. What is the name of the program or process?

Information for all processes is constantly refreshed. Friends are not 211.html "> I think the hacker in the movie is so. Now we have some understanding of the top command. Let's quit. What should I do? Too easy, press the "Q" button on the keyboard, you can.
