|
|
||
|
|
> Get or set program I/O scheduling class and priority.
|
||
|
|
> Scheduling classes: 1 (realtime), 2 (best-effort), 3 (idle).
|
||
|
|
> Priority levels: 0 (the highest) - 7 (the lowest).
|
||
|
|
> More information: <https://manned.org/ionice>.
|
||
|
|
|
||
|
|
- Run a command with the given scheduling class and priority:
|
||
|
|
|
||
|
|
`ionice -c {{scheduling_class}} -n {{priority}} {{command}}`
|
||
|
|
|
||
|
|
- Set I/O scheduling [c]lass of a running process with a specific [p]id, [P]gid or [u]id:
|
||
|
|
|
||
|
|
`ionice -c {{scheduling_class}} -{{p|P|u}} {{id}}`
|
||
|
|
|
||
|
|
- Run a command with custom I/O scheduling [c]lass and priority:
|
||
|
|
|
||
|
|
`ionice -c {{scheduling_class}} -n {{priority}} {{command}}`
|
||
|
|
|
||
|
|
- Ignore failure to set the requested priority:
|
||
|
|
|
||
|
|
`ionice -t -n {{priority}} -p {{pid}}`
|
||
|
|
|
||
|
|
- Run the command even in case it was not possible to set the desired priority (this can happen due to insufficient privileges or an old kernel version):
|
||
|
|
|
||
|
|
`ionice -t -n {{priority}} -p {{pid}}`
|
||
|
|
|
||
|
|
- Print the I/O scheduling class and priority of a running process:
|
||
|
|
|
||
|
|
`ionice -p {{pid}}`
|
