Adjust the priorities of running processes (POSIX)
renice prioritylevel [-g pgrp...] [-p pid...] [-u user...]
QNX Neutrino
The renice utility adjusts the priority of all the threads in one or more running processes. The specified prioritylevel is subtracted from the current priority of each selected process.
If you enter a: | renice: |
---|---|
Positive value (e.g., 2 or +2) | Lowers the priority of a process, making it nicer to other processes |
Negative value (e.g., -2) | Raises the priority of a process, making it meaner to other processes |
You can adjust the priority as follows:
If you're: | You can change to any priority: |
---|---|
A non-root user | From 1 to 63 |
root | From 1 to 255 |
If you don't have the appropriate privileges, you can renice only the processes you own. You can change the range of privileged priorities with the -P option for procnto.
Lower the priority of process 768 by 2:
renice 2 -p 768
