NAME
nice - set program priority
SYNOPSIS
nice(incr)
DESCRIPTION
The scheduling
priority of the process is augmented by
incr.
Positive priorities get less
service than normal.
Priority 10 is recommended to users
who wish to execute long-running programs
without flak from the administration.
Negative increments are ignored except on behalf of
the super-user.
The priority is limited to the range
-20 (most urgent) to 20 (least).
The priority of a process is
passed to a child process by
fork(2).
For a privileged process to return to normal priority
from an unknown state,
nice
should be called successively with arguments
-40 (goes to priority -20 because of truncation),
20 (to get to 0),
then 0 (to maintain compatibility with previous versions
of this call).
