renice(1M)              (BSD Compatibility Package)              renice(1M)


   NAME
         renice - 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

   SEE ALSO
         priocntl(1) in the User's Reference Manual.

   NOTES
         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.
