       NAME
             renice - (BSD) alter priority of running processes

       SYNOPSIS
             /usr/ucb/renice priority pid ...
             /usr/ucb/renice priority [-p pid ...] [-g pgrp ...] [-u username ...]

       DESCRIPTION
             The renice command alters the scheduling priority of one or
             more running processes.  By default, the processes to be
             affected are specified by their process IDs.  priority is the
             new priority value.

             The following options are available:

             -p pid ...  Specify a list of process IDs.

             -g pgrp ... Specify a list of process group IDs.  The
                         processes in the specified process groups have
                         their scheduling priority altered.

             -u user ... Specify a list of user IDs or usernames.  All
                         processes owned by each user have their scheduling
                         altered.

             Users other than the privileged user may only alter the
             priority of processes they own, and can only monotonically
             increase their nice value within the range 0 to 20.  This
             prevents overriding administrative fiats.  The privileged user
             may alter the priority of any process and set the priority to
             any value in the range -20 to 20.  Useful priorities are: 19
             (the affected processes will run only when nothing else in the
             system wants to), 0 (the base scheduling priority) and any
             negative value (to make things go very fast).

             If only the priority is specified, the current process
             (alternatively, process group or user) is used.

       FILES
             /etc/passwd         map user names to user ID's

      NOTICES
            If you make the priority very negative, then the process
            cannot be interrupted.

            To regain control you must make the priority greater than
            zero.

            Users other than the privileged user cannot increase
            scheduling priorities of their own processes, even if they
            were the ones that decreased the priorities in the first
            place.

            The priocntl command subsumes the function of renice.
