Question:Which commands are used to set a processor-intensive job to use less CPU time?

nice command is used for changing priority of the jobs.

Syntax: nice [OPTION] [COMMAND [ARG]…]
Range of priority goes from -20 (highest priority) to 19 (lowest).Priority is given to a job so that the most important job is executed first by the kernel and then the other least important jobs. This takes less CPU times as the jobs are scheduled and are given priorities so the CPU executes fast. The priority is given by numbers like -20 describe the highest priority and 19 describe the least priority.
