NAME
renice — set priorities of running processes
SYNOPSIS
renice [–n increment][–g–p –u] ID ...
renice priority [–p] pid ... [–g pgrp ...] [–p pid ...] [–u user ...]
renice priority –g pgrp ... [–g pgrp ...] [–p pid ...] [–u user ...]
renice priority –u user ... [–g pgrp ...] [–p pid ...] [–u user ...]
DESCRIPTION
Note: The
MPE/iX implementation of this utility does not function exactly as this man page
describes. For details, see the MPE/iX NOTES section at the end of this man page.
renice changes the priority of one or more running processes. Normal users can only
change the priority of processes that have the same real or effective user
ID as the real or
effective user ID of the process that calls renice. Privileged users can set the priority of any
process.
You can specify the new priority as a decimal integer, with lower values indicating more
urgent priority. The range of priorities is site-specific, and you may require appropriate privi-
leges for some priority values.
When you change the priority of a process group, this changes the priority of all processes in
that group.
If the string –– appears in the arguments, renice does not interpret it as the end of com-
mand line arguments. This is an exception to the usual
POSIX syntax rules.
Options
renice accepts the following options:
–g treats all following IDs (or just pgrps in the obsolescent versions) as process
group IDs.
–n increment adjusts the system scheduling priority of the specified processes by incre-
ment. Positive increments lower the priority while negative increments
result in a higher priority.
Note: Negative increments may require appropriate privileges.
–p treats all following IDs (or just pids in the obsolescent versions) as process
IDs.
–u treats all following IDs (or just users in the obsolescent versions) as either
user names or numeric user IDs.
