  • 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
