What is the purpose of the Linux nice command?

In the Linux system, the nice command is used to adjust the priority of processes. This command allows users to change the priority of processes, enabling them to be taken into consideration more in the system resource allocation. By using the nice command, the priority of a process can be increased or decreased, thus affecting its position in the system resource scheduling.

A lower priority value indicates a higher priority, while a higher priority value indicates a lower priority. When a process has a lower nice value, the system will allocate resources to this process more frequently, making it easier to schedule for execution. Conversely, when a process has a higher nice value, the system will allocate fewer resources to this process, reducing its execution frequency.

By using the nice command, users can adjust the priority of processes according to their needs, allowing for better control over the execution of processes in system resource allocation.
