chrt

chrt

The chrt command in Linux can be used to change the scheduling policy of a process. The scheduling policy is the way that the processor time is allocated to a process.

To use the chrt command, you use the following syntax:

chrt [options] [policy] [priority] [pid]
  • policy is the scheduling policy for the process.

  • priority is the priority of the process.

  • pid is the process ID.

policy has the following options:

  • BE : Background priority

  • RT : Real-time priority

  • FIFO : First-in, first-out priority

  • RR : Round-robin priority

priority can be a value from 0 to 99. The higher the value, the higher the priority of the process.

pid is the process ID. You can find the process ID using the ps command.

For example, to change the scheduling policy of the firefox process with PID 1234 to background priority, you would use the following command:

chrt -p BE 1234

To change the priority of the firefox process with PID 1234 to 10, you would use the following command:

chrt -p 10 1234

The chrt command can be used to change the scheduling policy of a process to improve the performance of the process.
