renice — stdin stdout - file -- opt --help --version
Synopsis
renice [+-N
] [options
]PID
While the nice
command can
invoke a program at a given nice level, renice
changes the nice level of an
already-running process. Here we increase the nice
level (decrease the priority) of
process 28734 by five:
➜ renice +5 -p 28734
Ordinary users can increase the nice level of their own processes, while the superuser can also decrease it (increasing the priority) and can operate on any process. The valid range is −20 to +20, but avoid high negative numbers or you might interfere with vital system processes.
Useful options
| Affect the given
process ID. You can omit the |
| Affect all processes owned by the given user. |
