@(#)nice.1 6.3 (Berkeley) 05/20/89

C 4 nice - run a command at low priority (sh only) nice [ - number ] command [ arguments ] Nice executes command with low scheduling priority. If the number argument is present, the priority is incremented (higher numbers mean lower priorities) by that amount up to a limit of 20. The default number is 10.

The super-user may run commands with priority higher than normal by using a negative priority, e.g. `--10'.

csh(1), nice(1), setpriority(2), renice(8) Nice returns the exit status of the subject command. Nice is particular to sh (1). If you use csh (1), then commands executed with ``&'' are automatically immune to hangup signals while in the background.

Nice is built into csh (1) with a slightly different syntax than described here. The form ``nice +10'' nices to positive nice, and ``nice -10'' can be used by the super-user to give a process more of the processor.
