The 'nice value' is a parameter in Unix-like operating systems that determines the priority of a process. It affects how much CPU time a process receives relative to other processes. The nice value ranges from -20 to 19:
- -20: Highest priority (the process will get more CPU time).
- 0: Default priority.
- 19: Lowest priority (the process will get less CPU time).
A lower nice value means higher priority, while a higher nice value means lower priority. Only the root user can set negative nice values. Adjusting the nice value can help manage system resources and improve performance, especially on busy systems.
