I. process definition

Linux is a multi-user and multi-task operating system. Multi-user means that multiple users can use the computer at the same time. Multi-task means that linux can execute multiple tasks at the same time. It can execute another task before it has finished. Every time a task is run, the system starts a process, which is an execution activity of a program in its own virtual address space. The reason for creating a process is to enable multiple programs to execute concurrently. So as to improve the resource utilization and throughput of the system.

Second, the method of viewing the process

We can view the progress through the ps command.

Command:

Ps aux

The ps command is used to report the process status of the current system. You can interrupt and delete unnecessary programs at any time with kill instructions.

Ps command 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 take up too much resources, and so on. In short, most of the information can be obtained by executing the command.

3. Parameter introduction:

A: displays all the process information under the current terminal, including the processes of other users.

U: use a user-based format to output process information.

X: displays the progress of the current user under all terminals.
