.SH DESCRIPTION
.I Nice
executes
.I command
with low scheduling priority.
If the
.I number
argument is present, the priority is incremented (higher
numbers mean lower priorities) by that amount up to a limit of 19.
The default
.I number
is 10.
.PP
The super-user may run commands with
priority higher than normal
by using a negative
.I number,
e.g.
.LR --10 .
.PP
.I Renice
increments the scheduling priority
of the processes with the named
.I process-ids
by
.IR number .
The default
.IR number
is 19,
making the process least likely to run.
.PP
Only the owner of the process
or the super-user may change the priority.
Only the super-user may use negative increments.
.PP
.I Nohup
executes
.I command
immune to hangup and terminate signals from the controlling terminal.
The priority is incremented by 5.
.PP
Any output not explicitly redirected is appended to
the file
.F nohup.out
in the current directory.

.SH BUGS
Quoted
.I arguments
don't work right in all cases.
The difficulty may be avoided by quoting the
.I command,
with arguments in inner quotes.
