alter priority of running processes

SYNTAX
/etc/renice priority [ [ -p ] pid ... ] [ [ -g ] pgrp ... ] [ [
-u ] user ... ]
/etc/renice nice pid [ pid ]
DESCRIPTION
Renice alters the scheduling priority of one or more running
processes. In the DG/UX System, users other than superuser can
alter the nice (priority) of processes they own, but only to a
higher number (lower priority).
Arguments are:
priority An integer in the range -20 to +20; 0 is the default.
pid A process identification number.
pgrp A process group ID.
user A user name.
nice An integer in the range 0 to 39; 19 is the default.
Options are:
-p Processes whose process ids are specified; this is the
default.
-g Processes in the specified process group.
-u Processes owned by the specified user.
Useful priorities in DG/UX are:
20 (39) The affected processes will run only when nothing else
in the system wants to.
0 (19) This is the ``base'' scheduling priority.
<0 (<19) Low numbers make processes go very fast.

EXAMPLE
/etc/renice +1 987 -u daemon root -p 32
changes the priority of process ID's 987 and 32, and all
processes owned by users daemon and root.
FILES
/dgux
/etc/passwd To map user names to user id's

BUGS
If you make the nice (priority) a very low number (e.g., -20),
the process cannot be interrupted. To regain control, make the
nice greater than 0.
Non-superusers cannot increase scheduling priorities of their own
processes, even if they were the ones that decreased the
priorities in the first place.
