NAME
     renice - alter priority of running processes

SYNOPSIS
     /usr/ucb/renice priority pid ...

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

AVAILABILITY

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.

     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.

OPTIONS
     -ppid...     Specify a list of process IDs.

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

     -uuser...    Specify a list of user IDs or  usernames.   All
                 processes owned by each user have their schedul-
                 ing altered.

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

     priocntl(1)

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 .
