NAME
renice -- alter priority of running processes
SYNOPSIS
renice priority [[-p] pid ...] [[-g] pgrp ...] [[-u] user ...]
renice -n increment [[-p] pid ...] [[-g] pgrp ...] [[-u] user ...]
DESCRIPTION
The renice utility alters the scheduling priority of one or more running
processes. The following who parameters are interpreted as process ID's,
process group ID's, user ID's or user names. The renice'ing of a process
group causes all processes in the process group to have their scheduling
priority altered. The renice'ing of a user causes all processes owned by
the user to have their scheduling priority altered. By default, the pro-
cesses to be affected are specified by their process ID's.
The following options are available:
-g Force who parameters to be interpreted as process group ID's.
-n Instead of changing the specified processes to the given prior-
ity, interpret the following argument as an increment to be
applied to the current priority of each process.
-u Force the who parameters to be interpreted as user names or user
ID's.
-p Reset the who interpretation to be (the default) process ID's.
For example,
renice +1 987 -u daemon root -p 32
would change the priority of process ID's 987 and 32, and all processes
owned by users daemon and root.
