Etiquette: Running Nice on other desktop machines

When using someone else's machine, it's polite to use the command nice and renice.

Nice changes the priority of a task. When using another machine, you want to set your task to a lower priority as to not interfere with the user's tasks. Priority ranges from -20 (highest) to 20 (lowest).

nice [options] [command]

Example:

nice -19 ~/run.py

UNIX priority levels are counted from negative (highest) to positive. Note that nice -n specifies a priority of n whereas nice --n specifies a priority of -n.

Renice allows you to reset the priority of a process that is already running.

renice [-n] [PID] [options]

Replace [-n] with the desired priority, and [PID] with the process ID number.
