What are the commands for managing processes in linux? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

1.ps

'ps' is the most basic command in Linux to browse processes in the system. Can list the processes running in the system, including process number, command, CPU usage, memory usage and so on. The following options can get more useful information.

Ps-a-lists all running / active processes ps-ef | grep-lists the processes that need ps-aux-displays process information, including processes without terminals (x) and for users (u), such as USER, PID,% CPU,% MEM, etc.

2.nice

With the help of the nice command, users can set and change the priority of the process. Raise the priority of a process, and the kernel allocates more CPU time slices to the process. By default, the process starts with a priority of 0. The process priority can be seen through the NI (nice value) column displayed by the top command.

Process priority values range from-20 to 19. The lower the value, the higher the priority.
