| 4 | .SH SYNOPSIS |
| 5 | .B renice |
| 6 | pid |
| 7 | [ priority ] |
| 8 | .SH DESCRIPTION |
| 9 | .I Renice |
| 10 | can be used by the super-user to alter the |
| 11 | priority of a running process. |
| 12 | By default, the nice of the process is made ``19'' which means that it |
| 13 | will run only when nothing else in the system wants to. This can be used |
| 14 | to nail long running processes which are interfering with interactive work. |

| 16 | .I Renice |

| 18 | Negative nices can be used to make things go very fast. |
