renice
RENICE(1) User Commands RENICE(1)
NAME
renice - alter priority of running processes
SYNOPSIS
renice [-n] priority [-gpu] 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 priority
Specify 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.
-g, --pgrp pgid...
Force the succeeding arguments to be interpreted as process group IDs.
-u, --user name_or_uid...
Force the succeeding arguments to be interpreted as usernames or UIDs.
-p, --pid pid...
Force the succeeding arguments to be interpreted as process IDs (the default).
-h, --help
Display a help text.
-V, --version
Display version information.
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:
renice +1 987 -u daemon root -p 32
NOTES
Users other than the super-user may only alter the priority of processes they own, and can only monotonically increase their ``nice value''
(for security reasons) within the range 0 to PRIO_MAX (20), unless a nice resource limit is set (Linux 2.6.12 and higher). The super-user
may alter the priority of any process and set the priority to any value in the range PRIO_MIN (-20) to PRIO_MAX. Useful priorities are: 20
(the affected processes will run only when nothing else in the system wants to), 0 (the ``base'' scheduling priority), anything negative
(to make things go very fast).
FILES
/etc/passwd
to map user names to user IDs
SEE ALSO
getpriority(2), setpriority(2)
BUGS
Non super-users can not increase scheduling priorities of their own processes, even if they were the ones that decreased the priorities in
the first place.
The Linux kernel (at least version 2.0.0) and linux libc (at least version 5.2.18) does not agree entirely on what the specifics of the
systemcall interface to set nice values is. Thus causes renice to report bogus previous nice values.
HISTORY
The renice command appeared in 4.0BSD.
AVAILABILITY
The renice command is part of the util-linux package and is available from Linux Kernel Archive <ftp://ftp.kernel.org/pub/linux/utils/util-
linux/>.
