NAME
nice, renice, nohup - run commands at low priority or immune
to hangup
SYNOPSIS
nice [ -number ] command [ argument ... ]
/etc/renice [ -number ] pid ...
nohup command [ argument ... ]
DESCRIPTION
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 19. The default number is 10.
The super-user may run commands with priority higher than
normal by using a negative number, e.g. `--10'.
Renice increments the scheduling priority of the processes
with the named process-ids by number. The default number is
19, making the process least likely to run.
Only the owner of the process or the super-user may change
the priority. Only the super-user may use negative incre-
ments.
Nohup executes command immune to hangup and terminate sig-
nals from the controlling terminal. The priority is incre-
mented by 5.
Any output not explicitly redirected is appended to the file
in the current directory.

BUGS
Quoted arguments don't work right in all cases. The diffi-
culty may be avoided by quoting the command, with arguments
