`renice`

Adjust the priorities of running processes (POSIX)

Syntax:

renice prioritylevel [-g pgrp...] 
       [-p pid...] [-u user...]

Runs on:

Neutrino

Options:

-g pgrp: Renice processes in this process group.
-p pid: Renice this process.
-u user: Renice processes owned by this user.
prioritylevel: The amount to adjust the priority by. Positive numbers lower the priority by that many full priority levels, while negative numbers raise the priority.

Description:

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.

Examples:

Lower the priority of process 768 by 2:

renice 2 -p 768

Exit status:

0: Successful completion.
> 0: An error occurred.
