# taskset
> Get or set a process' CPU affinity or start a new process with a defined CPU affinity.
- Get a running process' CPU affinity by PID:
`taskset --pid --cpu-list {{pid}}`
- Set a running process' CPU affinity by PID:
`taskset --pid --cpu-list {{cpu_id}} {{pid}}`
- Start a new process with affinity for a single CPU:
`taskset --cpu-list {{cpu_id}} {{command}}`
- Start a new process with affinity for multiple non-sequential CPUs:
`taskset --cpu-list {{cpu_id_1}} {{cpu_id_2}} {{cpu_id_3}}`
- Start a new process with affinity for CPUs 1 through 4:
`taskset --cpu-list {{cpu_id_1}},{{cpu_id_4}}`
