renice
RENICE(8) BSD System Manager's Manual RENICE(8)
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
renice alters the scheduling priority of one or more running processes. The following who parameters are interpreted as process ID's,
process group ID's, 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. By default, the processes to
be affected are specified by their process ID's.
Options supported by renice:
-g Force who parameters to be interpreted as process group ID's.
-n Instead of changing the specified processes to the given priority, 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.
-p Resets 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.
Users other than the super-user may only alter the priority of processes they own, and can only monotonically increase their ``nice value''
within the range 0 to PRIO_MAX (20). (This prevents overriding administrative fiats.) 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: 0, the ``base'' scheduling priority; 20, the affected processes will run only when nothing at the base priority wants
to; anything negative, the processes will receive a scheduling preference.
FILES
/etc/passwd to map user names to user ID's
SEE ALSO
nice(1), getpriority(2), setpriority(2)
HISTORY
The renice command appeared in 4.0BSD.
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.
