Questions tagged [nice]

nice is a UNIX kernel call and the name of a utility employed to lower or raise a process' CPU priority.

nice is a program found on Unix and Unix-like operating systems such as Linux.

It directly maps to a kernel call of the same name. nice is used to invoke a utility or shell script with a particular priority, thus giving the process more or less CPU time than other processes. A niceness of −20 is the highest priority and 19 or 20 is the lowest priority. The default niceness for processes is inherited from its parent process, usually 0.
