NAME
       renice - alter priority of running processes

SYNOPSIS
       /etc/renice [ priority ] [ [ -p ] pid ... ] [ [ -g ] pgrp ... ] [ [
       -u ] user ... ]

       /etc/renice priority pid [ pid ]

   where:
       priority  An integer in the range -20 to +19.  If you supply a number
                 less than -20, renice uses -20 (which puts your process at
                 the highest possible priority).  If you supply a number
                 greater than 19, renice uses 19 (lowest possible priority).
                 In the first syntax given above, you can omit priority and
                 have renice assume 0 as the default.  In the second form of
                 syntax, you must supply a priority value.
       pid       A process identification number.
       pgrp      A process group ID.
       user      A user name.

DESCRIPTION
       Renice resets the scheduling priority of one or more running
       processes.  Users without appropriate privilege can reset the
       priority of processes they own, but only to a higher number (lower
       priority).  A user with appropriate privilege can raise as well as
       lower priorities.  For systems supporting the DG/UX Capability
       Option, appropriate privilege is defined as having one or more
       specific capabilities enabled in the effective capability set of the
       user.  See capdefaults(5) for the default capabilities for this
       command.

       On systems without the DG/UX Capability Option, appropriate privilege
       means that your process has an effective UID of root.  See the
       appropriateprivilege(5) man page for more information.

   Options
       -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:

       19        The affected processes will run only when nothing else in
                 the system wants to.

       0         This is the "base" scheduling priority.

       <0        Lower numbers make processes go faster (the lower limit is
                 -20).

EXAMPLE
            /etc/renice -10 987 -u daemon root -p 32

       Resets to -10 the priority of processes with IDs 987 and 32, and all
       processes owned by users daemon and root.

            /etc/renice -p 12488 12489 12490

       Resets to 0 the priority of processes 12488, 12489, and 12490.

            /etc/renice 19 12488 12489 12490

       Resets to 19 the priority of processes 12488, 12489, and 12490.

FILES
       /dgux
       /etc/passwd    To map user names to user ID numbers

       capdefaults(5).

NOTES
       If you make the priority a very low number (such as -20), you cannot
       interrupt the process.  To regain control, reset the priority to a
       number greater than 0.

       Users without appropriate privilege cannot increase scheduling
       priorities (that is, lower the priority numbers) of their own
       processes, even if they are the ones who originally decreased the
       priorities.
