To change job scheduling policy in Linux.

To change job scheduling policy (job scheduler) in Linux, we can use "chrt" to achieve our goal.

Scheduling policies: 

-b | --batch set policy to SCHED_BATCH
-f | --fifo set policy to SCHED_FIFO
-i | --idle set policy to SCHED_IDLE
-o | --other set policy to SCHED_OTHER
-r | --rr set policy to SCHED_RR (default)

chrt --rr <priority between 1-99> <command>

chrt --rr 99 ls
