In Linux we can set guidelines for the CPU to follow when it is looking at all the tasks it has to do. These guidelines are callednicenessornice value. The Linux niceness scale goes from -20 to 19. The lower the number the more priority that task gets. If the niceness value is hi...

renice命令是Linux系统中用于重新设置一个或多个正在运行的进程的调度优先级的工具。通过改变进程的“nice值”,renice能够影响进程的执行优先级,使得系统能够根据需要调整不同进程的资源分配。 2、命令语法 renice priority [ [-p] pid ... ] [ [-g] pgrp ... ] [ [-u] user ... ] ...
Of course, in Linux you can control as much as you want, so, you can also control how much priority something must have in the system when running it. How to check the niceness or priority of a process? If you runthe ps command, you can see what processes are currently running on ...
You can use renice command to change the nice value of a running process.In a nutshell the nice value scheme provides a facility where you run lengthy jobs at a lower priority while processes that are required to be completed in a short time are run at a higher priroty level.# ps -...
