This subchapter looks at nice, a UNIX (and Linux) command.
Most of the daily work for a system administrator is making sure that system resources aren’t overloaded so that everythign runs smoothly.
Sometimes a program will hog the CPU. This may be due to an infinite loop, repeatedly forking itself, or other bug, or it may be due to the nature of the processing being done.
In either case, the system administrator can use the nice command to adjust the CPU priority of each runnign process so that the entire system runs smoothly.
Coding example: I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).
