Synopsis

renice [priority] [options] [target]

Controls the scheduling priority of various processes as they run. May be applied to a process, process group, or user (target). A privileged user may alter the priority of other users' processes. priority must, for ordinary users, lie between 0 and the environment variable PRIO_MAX (normally 20), with a higher number indicating increased niceness. A privileged user may set a negative priority, as low as PRIO_MIN, to speed up processes.

- num

Specify number by which to decrease current priority of process, rather than an absolute priority number.
