Brief Introduction to the Process status of the Linux operating system

Article Title: describes the process status of a Linux operating system. Linux is a technology channel of the IT lab in China. Some basic classification processes, such as desktop applications, Linux system management, kernel research, embedded systems, and open source, will change the state according to the environment during execution. The Linux Process has the following statuses:

Running

The process is running (it is the current process of the system) or ready to run (it is waiting for the system to allocate CPU to it ).

Waiting

A process is waiting for an event or resource. In Linux, the waiting process is divided into two types: resumable and non-disruptive. A process that can be interrupted by signals. A process that can be interrupted can be waited directly under hardware conditions and cannot be interrupted under any circumstances.

Stopped

The process is stopped, usually by receiving a signal. The process being debugged may be stopped.

Zombie (defunct)

This is a process terminated due to the death of the parent process, but the task_struct structure is retained in the task data.
