NAME
renice - alter priority of running processesSYNOPSIS
renice [-n] priority [-g|-p|-u] identifier...DESCRIPTION
renice alters the scheduling priority of one or more running processes. The first argument is the priority value to be used. The other arguments are interpreted as process IDs (by default), process group IDs, user IDs, or user names. renice'ing a process group causes all processes in the process group to have their scheduling priority altered. renice'ing a user causes all processes owned by the user to have their scheduling priority altered.OPTIONS
-n, --priority prioritySpecify the scheduling priority to be
used for the process, process group, or user. Use of the option -n or
--priority is optional, but when used it must be the first
argument.
Interpret the succeeding arguments as process
group IDs.
Interpret the succeeding arguments as process
IDs (the default).
Interpret the succeeding arguments as
usernames or UIDs.
Display help text and exit.
Print version and exit.

NOTES
Users other than the superuser may only alter the priority of processes they own. Furthermore, an unprivileged user can only increase the "nice value" (i.e., choose a lower priority) and such changes are irreversible unless (since Linux 2.6.12) the user has a suitable "nice" resource limit (see ulimit(1p) and getrlimit(2)).HISTORY
The renice command appeared in 4.0BSD.EXAMPLES
The following command would change the priority of the processes with PIDs 987 and 32, plus all processes owned by the users daemon and root:SEE ALSO
