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.
